General
When a plant's use is governed by national fire reaction regulations, its fire performance is determined by the properties of its components This performance must be classified according to EN 13501-1 into one of the following categories: a) Class A1, which does not require testing if it meets the criteria outlined in section 4.7.2, or b) Classes A1 to E, which are defined based on the testing results of the plant's constituent materials as specified in section 4.7.3 of the standard.
Plants classified as Class A1 without the need for testing
The fire performance classification of a plant can be declared as Class A1 without testing if its constituent materials contain no more than 1% of uniformly distributed organic material by mass or volume, whichever is more stringent Additionally, any external coatings applied to the plant's surface must consist of inorganic materials that are also classified as Class A1.
1) See Decision of the Commission 96/603/EC of 1996-10-04 (see OJEU L 267 of 1996-10-19), as twice amended by 2000/605/EC of 2000-09-26 (see OJEU L 258 of 2000-10-12) and by 2003/424/EC of 2003-06-06 (see OJEU L 144 of 2003-06-12).
Plants classified according to test results
To assess the fire performance of a plant, all constituent materials, including any surface coatings, must be classified according to EN 13501-1 Only the lowest classification among these materials will be declared The classification for each material is determined through specific test methods outlined in the relevant standards.
A constituent material of a plant is defined as one that can significantly influence the fire performance of that plant As outlined in EN 13501–1, this definition applies in various scenarios.
— a homogeneous plant, its material, or
A non-homogeneous plant is defined by its substantial components, which are materials that make up a significant portion of the plant Specifically, a layer is classified as a substantial component if it has a mass per unit area of at least 1.0 kg/m² or a thickness of 1.0 mm or greater.
Test specimens used for the test methods applicable for this classification shall be prepared according to
EN 13501-1 and to the relevant standards referred therein
In addition, with regard to the SBI test according to EN 13823, when applied, the test specimen shall be prepared and mounted as specified in 4.7.3.2
4.7.3.2 Sizes and mounting of the test specimen
The test specimen of each constituent material shall be in accordance with EN 13823 in a flat-sheet form of the following sizes:
Noise level
The manufacturer must report the A-weighted emission sound pressure level measured at a distance of 1 meter from the plant, following the guidelines of EN ISO 20361 It is essential that the pump operates at its best efficiency point during this measurement.
If an A-weighted emission sound pressure level is above 80 dB, the sound power level shall be determined according to EN ISO 20361 and shall be declared
Where the manufacturer declares that the A-weighted emission sound pressure level is equal to 70 dB, although it might be smaller, the manufacturer may state “70 dB(A)”
If a manufacturer states a sound pressure level below 70 dB(A), the facility must be assessed in accordance with EN ISO 20361, and the relevant test results must be reported.
Durability
General
Lifting plants designed for faecal-free wastewater are reliable products with proven performance tailored for specific applications, backed by extensive experience over time Their durability is guaranteed by adhering to established standards that reflect the latest advancements in the field.

Dangerous substances
National regulations regarding hazardous substances may necessitate verification and declaration upon release, as well as content disclosure, when construction products governed by this standard enter specific markets In the absence of European harmonized testing methods, such verification and declaration should adhere to the national regulations applicable in the location of use.
Need for a stand-by pumping device (twin lifting plant)
In situations where halting the inflow to the lifting plant during regular operations is unfeasible, it is essential to install a standby pumping device with equivalent capacity at the duty point of the lifting plant, which will automatically activate when required.
Preparation
General requirements
Testing will be conducted on a plant that meets the specified shape, dimensions, and materials outlined in the testing documentation The purpose of the test is to confirm compliance with the relevant standards Tightness testing will utilize water, with the water temperature not exceeding 35 °C unless otherwise specified.
Testing for hydraulic performance
The hydraulic and electrical characteristics must be verified in accordance with EN ISO 9906:2012, grade 3, including the specified minus tolerances Prior to testing, the pumping device should operate continuously for a minimum of 5 minutes, with the testing duration set between 10 to 15 minutes Compliance with the minimum flow velocity outlined in section 4.3.4 will be assessed based on the hydraulic characteristics obtained from testing Performance data should be gathered without the non-return valve, which is also applicable for pumps under 1 kW, using tolerances for motor power consumption between 1 kW and 10 kW If the unit includes an integrated non-return valve, the values obtained with it installed may be utilized.
Tightness testing
Watertightness
During the test, water at a maximum temperature of 20 °C is filled to the upper edge of the collection tank, with the pump remaining inactive For on-site constructed tanks, watertightness must be verified in accordance with EN 12566-4 after installation, ensuring that no leaks are detected over a 10-minute period.
Connection to the discharge pipe
The connection to the discharge pipe shall be tested for a period of 10 min at 1,5 times the maximum operating pressure of the lifting device No leakage shall be observed.
Hot water test
If the manufacturer specifies an inflow temperature exceeding 35 °C, a hot water tightness test without overpressure must be conducted for a specified duration and/or volume.
For collection tanks with a useful volume exceeding 10 liters, fill the tank with water at a temperature of (35 ± 2) °C up to the switch-off level Then, add either 20% of the useful volume or a minimum of 10 liters of water at the declared temperature, ensuring it does not exceed the switch-on level Maintain the resulting water temperature within a tolerance of ± 5 °C.
For collection tanks with a capacity of less than 10 liters, it is essential to fill the tank to the switch-on level using water maintained at a declared temperature within ± 2 °C Additionally, the water temperature must remain stable, with a tolerance of ± 5 °C.
During the hot water test, the plant must operate continuously at the specified flow rate and rated power consumption without any malfunctions, and there should be no leakage observed throughout the 10-minute duration.

6 Assessment and verification of constancy of performance - AVCP
General
Lifting plants for wastewater must comply with established standards and the performance specifications outlined by the manufacturer in the declaration of performance (DoP).
— determination of the product-type on the basis of type testing;
— factory production control by the manufacturer, including product assessment
The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s).
Type testing
General
Manufacturers must determine all performance characteristics outlined in this standard, except for the essential ones, when declaring their respective performances However, if the standard allows, these declarations can be made without conducting tests, such as by utilizing existing data, CWFT, or conventionally accepted performance metrics.
Previous assessments conducted in line with this standard may be considered valid if they were executed using the same or a more stringent testing method, under the same AVCP system, and pertain to the same product or products with similar design, construction, and functionality, ensuring that the results are relevant to the product in question.
NOTE 1 Same AVCP system means testing by an independent third party
For assessment purposes, products from the manufacturer can be categorized into families, where the characteristics of one or more products are deemed representative of those same characteristics across all products within the family.
NOTE 2 Products may be grouped in different families for different characteristics
Reference to the assessment method standards should be made to allow the selection of a suitable representative sample
In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or modified lifting plant for wastewater (unless a member of the same product range); or
— at the beginning of a new or modified method of production (where this may affect the stated properties); or
Whenever there is a change in the design of the lifting plant, the raw materials, the component suppliers, or the production methods—provided these changes significantly impact one or more characteristics—appropriate characteristics must be reassessed and repeated as necessary.
When components are utilized with predefined characteristics established by the manufacturer through assessments based on other product standards, there is no need for re-evaluation of these characteristics It is essential to document the specifications of these components.
Products with regulatory markings that comply with relevant harmonized European standards are assumed to meet the performance claims stated in the Declaration of Performance (DoP) However, this assumption does not absolve the lifting plant manufacturer from the responsibility of ensuring that the entire lifting plant is properly manufactured and that its components possess the declared performance values.
Test samples, testing and compliance criteria
Type testing shall be carried out on one sample of the wastewater lifting plant with the lowest rated performance from each series (e.g hydraulic type, collection tank size) See Table 2
For on-site constructed tanks, watertightness is not included in the type testing; however, it must be verified according to section 5.2.1 Additionally, for wastewater lifting plants with on-site tanks, noise emission testing is not mandatory during type testing.
Table 2 — Number of samples to be tested and compliance criteria
Characteristic Requirement Assessment method No of samples Compliance criteria
Reaction to fire 4.7 EN 13501 one 4.7
— Pipe connections 4.3.2 and 4.3.6 5.2.2 one 4.3.2 and 4.3.6
— Load bearing capacity of collection tank 4.2.1 5.1.1 one 4.2.1
— structural stability of collection tank 4.2.1 5.1.1 one 4.2.1
Noise level 4.8 EN ISO 20361 one 4.8
For the type test the following documentation shall be provided:
— drawings, including information on materials used;
— operating and maintenance instructions (acceptable in manuscript form).
Test reports
Test reports documenting the product type must be retained by the manufacturer for a minimum of 10 years following the last production date of the lifting plant for faecal-free wastewater.
Shared other party results
A manufacturer can leverage product type determination results obtained from another source, such as another manufacturer or a product developer, to support their own performance declaration for a product that shares the same design, dimensions, raw materials, constituents, and manufacturing methods, as long as certain conditions are met.
— the results are known to be valid for products with the same essential characteristics relevant for the product performance;
The other party responsible for determining the product type must provide the manufacturer with the test results and report, which are essential for confirming the product's performance related to specific characteristics Additionally, they must share information about the production facilities and the production control process relevant for Factory Production Control (FPC).
— the manufacturer using other party results accepts to remain responsible for the product having the declared performances and he also:
The product must maintain identical performance characteristics as the one evaluated for product type determination, ensuring no significant differences in production facilities or the production control process compared to the original product.
A copy of the product type determination report is maintained, which includes essential information for verifying that the product is manufactured in accordance with the same design, using identical raw materials, constituents, and manufacturing methods.
Cascading determination of the product type results
Certain construction products are supplied by companies that provide some or all components to an assembler, who then manufactures the final product in their factory based on an agreement.
A supplier legally engaged in manufacturing or assembling products may be responsible for determining the product type based on essential characteristics of an end product, which is later manufactured or assembled by other firms In this process, the supplier must provide an assembled product using components from itself or other sources, along with a product type determination report for the assemblers, who are the actual manufacturers To address this scenario, the concept of cascading determination of the product type can be included in the technical specifications, particularly for characteristics involving a notified product certification body or a notified test laboratory.
The supplier's product type report, obtained from tests conducted by a notified body, can be utilized for regulatory marking by assemblers without needing to engage a notified body again for the determination of essential characteristics that have already been tested, as long as certain conditions are met.
The assembler produces a product using the same combination of components and assembly methods as specified in the supplier's product type report If the report is based on a component combination that does not accurately represent the final market product or if the assembly deviates from the supplier's instructions, the assembler must submit the finished product for a new product type determination.
2) The formulation of such an agreement can be done by licence, contract, or any other type of written consent
3) This can be, for instance, a contract, license or whatever kind of written agreement, which should also contain clear provisions with regard to responsibility and liability of the component producer (supplier, on the one hand, and the assembler of the finished product, on the other hand)
— the supplier has notified to the manufacturer the instructions for manufacturing/assembling the product and installation guidance;
The assembler is responsible for ensuring the product is assembled correctly, following the manufacturing and assembly instructions provided by the supplier.
The manufacturing and assembly instructions, along with installation guidance provided by the supplier, are essential components of the assembler's factory production control system and play a crucial role in determining the product type report.
The assembler must maintain documented evidence that the components used and the manufacturing process align with the specifications outlined in the supplier's product type report, for which a copy must be retained.
The assembler is responsible for ensuring that the product meets the declared performance standards, including its design and manufacturing, regardless of any agreements with the supplier regarding liability This responsibility is affirmed when the assembler affixes the regulatory marking to the product.
Factory production control (FPC)
General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market comply with the declared performance of the essential characteristics
The FPC system will include procedures, regular inspections, tests, and assessments to manage raw materials, components, equipment, the production process, and the final product All elements and requirements established by the manufacturer will be systematically documented through written policies and procedures.
This factory production control system documentation aims to establish a shared understanding of performance evaluation, ensuring that product performance requirements are met and the production control system operates effectively It integrates operational techniques and measures necessary for maintaining and verifying that the product complies with the declared performance of its essential characteristics.
In case the manufacturer has used shared or cascading product type results, the FPC shall also include the appropriate documentation as foreseen in 6.2.4 and 6.2.5.
Requirements
The manufacturer must ensure the effective implementation of the FPC system according to the product standard It is essential to document the tasks and responsibilities within the production control organization and maintain this documentation regularly.
The roles and responsibilities of personnel involved in managing, executing, or verifying work that impacts product consistency must be clearly defined This is especially crucial for those tasked with initiating preventive measures against product inconsistencies, addressing issues when they arise, and identifying and documenting problems related to product consistency.
Personnel involved in tasks that impact product performance must possess the necessary education, training, skills, and experience, with proper records maintained to ensure their competence.
In each factory the manufacturer may delegate the action to a person having the necessary authority to:
— identify procedures to demonstrate constancy of performance of the product at appropriate stages;
— identify and record any instance of non-constancy;
— identify procedures to correct instances of non-constancy
The manufacturer must create and maintain up-to-date documentation for factory production control (FPC) that aligns with the product and manufacturing process The FPC system should instill confidence in the product's consistent performance, which requires: a) developing documented procedures and instructions for FPC operations based on technical specifications; b) effectively implementing these procedures; c) recording operations and their outcomes; and d) utilizing these results to address deviations, rectify non-conformities, and, if necessary, revise the FPC to eliminate the causes of performance inconsistency.
In subcontracting scenarios, the manufacturer must maintain overall control of the product and ensure access to all necessary information to meet their responsibilities as outlined by this European Standard.
When a manufacturer outsources aspects of a product's design, manufacturing, assembly, packing, processing, or labeling to subcontractors, the subcontractor's Factory Production Control (FPC) may be considered relevant for the specific product.
The manufacturer who subcontracts all of his activities may in no circumstances pass the above responsibilities on to a subcontractor
Manufacturers with a Factory Production Control (FPC) system that meets EN ISO 9001 standards and adheres to the provisions of the current European Standard are deemed to fulfill the FPC requirements outlined in Regulation (EU) No 305/2011.
All weighing, measuring and testing equipment shall be calibrated and regularly inspected according to documented procedures, frequencies and criteria
Regular inspection and maintenance of all manufacturing equipment are essential to prevent inconsistencies in the production process due to use, wear, or failure These inspections and maintenance activities must follow the manufacturer's written procedures, with records retained for the duration specified in the manufacturer's FPC guidelines.
All incoming raw materials and components must have documented specifications, along with an inspection scheme to ensure compliance When using supplied kit components, their performance consistency must align with the relevant harmonized technical specifications.
Individual faecal-free lifting plants must be identifiable and traceable to their production origin Manufacturers are required to implement written procedures that ensure regular inspections of processes related to the application of traceability codes and markings.
The manufacturer shall plan and carry out production under controlled conditions
The manufacturer shall establish procedures to ensure that the stated values of the characteristics he declares are maintained The characteristics, and the means of control, are given in Table 3
Table 3 — Product testing of finished products

Noise level 4.8 EN ISO 20361 Every 5 years
The frequency and extent of sampling dangerous substances are influenced by the production program, scale of production, and manufacturing processes at each factory It is essential to conduct checks on at least one plant per 100 or per production month and type Additionally, if the characteristics have been established by the components supplier, retesting by the lifting plant manufacturer is not required.
The manufacturer must establish documented procedures for handling non-compliant products All incidents of non-compliance should be recorded as they happen, and these records must be maintained for the duration specified in the manufacturer's written procedures.
If a product does not meet the acceptance criteria, the regulations for non-compliant products will be enforced Immediate corrective actions must be implemented, and any non-compliant products or batches should be isolated and clearly identified.
Once the fault has been corrected, the test or verification in question shall be repeated
All control and test results must be accurately documented, including the product description, manufacturing date, adopted test method, test results, and acceptance criteria, all signed by the responsible individual.
Any control results that do not comply with this European Standard must have documented corrective measures taken to address the issue, such as conducting additional tests, modifying the manufacturing process, or discarding or rectifying the product.
The manufacturer shall have documented procedures that instigate action to eliminate the cause of non- conformities in order to prevent recurrence
The manufacturer shall have procedures providing methods of product handling and shall provide suitable storage areas preventing damage or deterioration.
Product specific requirements
The FPC system shall address this European Standard and ensure that the products placed on the market comply with the declaration of performance
The FPC system must incorporate a product-specific FPC that outlines procedures for demonstrating product compliance at various stages This includes controls and tests to be conducted before and during manufacturing, as specified in the FPC test plan, as well as verifications and tests on finished products, also following the frequency established in the FPC test plan.
When a manufacturer relies solely on finished products, the processes outlined in section b) will ensure that the product meets compliance standards equivalent to those achieved through Factory Production Control (FPC) during production.
When a manufacturer conducts certain production processes in-house, it can lead to a reduction in operations categorized under b), which may be partially substituted with those under a) Typically, the greater the extent of production handled by the manufacturer, the more operations under b) can be replaced by those under a).
In any case the operation shall lead to an equivalent level of compliance of the product as if FPC had been carried out during the production
NOTE Depending on the specific case, it can be necessary to carry out the operations referred to under a) and b), only the operations under a) or only those under b)
The operations mentioned in section a) pertain to the intermediate states of products during manufacturing, including adjustments to machines and measuring equipment The selection of controls and tests, along with their frequency, should be determined by factors such as the product type and composition, the complexity of the manufacturing process, and the sensitivity of product features to variations in manufacturing parameters.
The manufacturer must create and keep records that demonstrate the sampling and testing of production These records should clearly indicate whether the production meets the specified acceptance criteria and must be retained for a minimum of three years.
Initial inspection of factory and of FPC [only for products covered by AVCP system 1]
The initial inspection of the factory and the Factory Production Control (FPC) is conducted once the production process is complete and operational This assessment includes a review of the factory and FPC documentation to ensure compliance with the requirements outlined in sections 6.3.2 and 6.3.3.
During the inspection, it is essential to confirm that all necessary resources for achieving the product characteristics outlined in this European Standard are properly implemented Additionally, it must be ensured that the FPC procedures align with the FPC documentation and are effectively followed Lastly, the product must be verified to comply with the product type samples, ensuring that its performance meets the Declaration of Performance (DoP) requirements.
All sites conducting final assembly or testing of the product must be evaluated to ensure compliance with specified conditions If the FPC system encompasses multiple products, production lines, or processes, and the general requirements are confirmed for one, there is no need to reassess these requirements for others.
All assessments and their results shall be documented in the initial inspection report.
Continuous surveillance of FPC [only for products covered by AVCP system 1]
Annual surveillance of the FPC will involve a comprehensive review of the FPC test plans and production processes for each product This assessment aims to identify any changes made since the previous evaluation, with a focus on determining the significance of those changes.
Checks shall be made to ensure that the test plans are still correctly implemented and that the production equipment is still correctly maintained and calibrated at appropriate time intervals
Records of tests and measurements conducted during production and on finished products must be reviewed to confirm that the obtained values align with those of the samples used for product type determination, ensuring appropriate actions are taken for any non-compliant products.
Procedure for modifications
Any changes to the product, production process, or FPC system that may impact the declared product characteristics must lead to a reassessment of all affected performance characteristics This reassessment should follow the product type determination process outlined in section 6.2.1.
Where relevant, a re-assessment of the factory and of the FPC system shall be performed for those aspects, which may be affected by the modification
All assessments and their results shall be documented in a report.
One-off products, pre-production products (e.g prototypes) and products produced in
The lifting plant produced as a one-off, as prototypes assessed before full production is established, and as products produced in very low quantities shall be assessed as follows
For type assessment, the provisions of 6.2.1, 3rd paragraph apply, together with the following additional provisions:
— in case of prototypes, the test samples shall be representative of the intended future production and shall be selected by the manufacturer;
— on request of the manufacturer, the results of the assessment of prototype samples may be included in a certificate or in test reports issued by the involved third party
The FPC system for one-off products and those produced in minimal quantities must guarantee adequate raw materials and components for production Relevant provisions regarding these materials will be enforced as necessary Additionally, manufacturers are required to keep records that enable product traceability.
For prototypes intended for series production, it is essential to conduct an initial inspection of the factory and the FPC prior to the commencement of production or the implementation of the FPC This assessment will evaluate key factors to ensure readiness for mass manufacturing.
During the initial assessment of the factory and Factory Production Control (FPC), it is essential to verify that all necessary resources for achieving the product characteristics outlined in the European Standard are available Additionally, it must be confirmed that the FPC procedures, as per the FPC documentation, are effectively implemented and followed Furthermore, procedures should be established to demonstrate that the factory's production processes can consistently produce a product that meets the requirements of the European Standard, ensuring that the final product is identical to the samples used for product type determination and compliance verification.
