6 Assessment and verification of constancy of performance - AVCP
General
The compliance of radiators and convectors with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by:
— 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 performances.
Type testing
General
Manufacturers must determine all performance characteristics outlined in this standard when declaring their respective performances, unless the standard allows for declarations based on existing data, classification without additional testing (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 identical design, construction, and functionality, ensuring that the results are relevant to the product in question.
NOTE Same AVCP system means testing by an independent third party, under the responsibility of a notified product certification body, when relevant
For assessment purposes, products from the manufacturer can be categorized into families, where the characteristics of one or more products are deemed representative of the same characteristics across all products within that family.
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 radiator and convector (unless it is a member of the same type of radiator or convector), 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 radiators and convectors, the raw materials, suppliers of components, or production methods, it is essential to repeat the appropriate tests for the relevant characteristics This is particularly important if such changes significantly impact one or more characteristics Notably, the thermal output must not decrease by more than 4% compared to the results of the original type-test.
When components, such as coatings, have 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.
It is recommended that the manufacturers of radiators and convectors request the documented specifications from suppliers of raw materials and components (i.e coating paints, steel, aluminium, etc.)
Products marked in compliance with relevant European standards are assumed to meet the performance claims stated in the Declaration of Performance (DoP) However, manufacturers of radiators and convectors remain responsible for ensuring that both the complete units and their individual components are manufactured correctly and achieve the declared performance values.
The number of samples of radiators and convectors to be tested/assessed shall be in accordance with Table 1

ZA.2.2 Declaration of performance (DoP)
The manufacturer draws up the DoP and affixes the CE marking on the basis of the different AVPC systems set out in Annex V of the Regulation (EU) No 305/2011:
In case of products under system 1
— the factory production control and further testing of samples taken at the factory according to the prescribed test plan, carried out by the manufacturer; and
The certificate of constancy of performance is issued by a notified product certification body, based on the determination of product type through type testing, sampling, type calculation, and descriptive documentation This process includes an initial inspection of the manufacturing plant, evaluation of factory production control, and ongoing surveillance and assessment of production practices.
In case of products under system 3
— the factory production control carried out by the manufacturer; and
The product type is determined through type testing conducted by a notified testing laboratory, which is based on samples provided by the manufacturer, type calculations, tabulated values, or descriptive documentation of the product.
In case of products under system 4
— the factory production control carried out by the manufacturer;
— the determination by the manufacturer of the product-type on the basis of type testing, type calculation, tabulated values or descriptive documentation of the product
