National foreword
This British Standard has been prepared under the direction of the Technical Committee B/542, Roofing and cladding products for discontinuous laying, and is
the English language version of EN 501:1994 Roofing products from metal
sheet — Specification for fully supported roofing products of zinc sheet, published
by the European Committee for Standardization (CEN)
EN 501 was produced as a result of international discussions in which the UK took an active part
A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application
Compliance with a British Standard does not of itself confer immunity from legal obligations.

0 Introduction
Figure 1 indicates the position of this standard in the CEN framework of standards
In this standard the performance of the product has been defined as far as possible in terms of a number
of type tests
The performance of a roof constructed with these products depends not only on the properties of the product
as it is required by this standard, but also on the design, construction and performance of the roof as a whole in relation to the environment and conditions of use
1 Scope
This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from Zinc-copper-titanium1) alloy sheet with or without additional coatings
The standard establishes the general characteristics, definitions, labelling and quality control for the products Products can be prefabricated or semiformed products (e.g interlocking tiles, slates, flashings)
as well as strip, coil, sheet for on-site-formed applications (e.g standing seam roofs, roll cap)
The standard applies to all discontinuously laid and fully supported roofing made of Zinc-copper-titanium alloy (Zn-Cu-Ti) No requirements for application (e.g methods of fixing, supporting construction, design
of roof system, execution of connections and flashings) are included It defines the requirements for roofing products made from zinc sheets, slit coils, coils and cut lengths to comply with normal service conditions NOTE The standard deals partly with flat products, partly with formed (prefabricated) products Valuable information regarding preformed products is found in prEN 506.

4 Requirements
4.1 General
Elements made of sheets, cut lengths, coils and slit coils can be cut, bent, seamed, formed and soldered without difficulty within the given limits of the properties listed in the respective material specifications The product properties depend upon its shape and the material used Requirements for materials are specified in prEN 988
The material tests (metal sheet, paint, surface treatment, etc.) are the responsibility of the material manufacturer and will be supplied on request by the product manufacturer
In this standard account is taken as far as possible of the essential requirements in the Construction Products Directive
4.2 Material requirements
4.2.1 General
The Zinc-copper-titanium alloy can be either cast in slabs or continuously cast These shall be rolled into coils The sheets and cut lengths are cut from coils or slit coils
Zinc-copper-titanium alloy is suitable for fabrication of fully supported roofing products either in an industrial process or by an on-site process
4.2.2 Chemical composition
The chemical composition is specified in prEN 988
4.2.3 Physical and mechanical properties
The physical and mechanical properties are specified in prEN 988
4.2.4 Organic coatings or chemical treatments on zinc sheet
Coatings shall be selected depending on processing and service conditions
Within this standard, specified organic coatings are acrylic paint coating (AY), polyester (SP) or
silicon-polyester (SP-SI) paint coating, polyvinylidene fluoride paint coating (PVDF),
polyvinylchloride(plastisol) coating [PVC(P)] Chemical treatment may be used to provide a preweathered surface (PW)
4.2.5 Surface appearance of zinc without additional organic coating
The surface of the product shall be smooth; i.e free from large blisters Superficial striations, small blisters and rolling marks are acceptable insofar as they do not hamper fabrication
Surface flaws such as white rust, grease or oil marks are acceptable since they fade, as the weathering patina forms, without undermining the properties of the metal
4.3 Product requirements
4.3.1 Mechanical properties
Mechanical properties are specified in prEN 988
4.3.2 Dimensions and tolerances
Dimensions and tolerances of sheet and coil are specified in prEN 988 The minimum nominal thickness allowed for fully supported roofing products is 0,6 mm
4.3.3 Shape and tolerances for formed (prefabricated) products
Formed (prefabricated) products are divided into two categories:
a) those to be joined by on-site folding processes
b) those to be joined without on-site folding processes
SP-SI silicon-polyester paint coating
PVDF polyvinylidene fluoride paint coating
PVC(P) polyvinylchloride(plastisol) coating, applied by coil coating process
PW preweathered surface by chemical treatment
Trang 11EN 501:1994
4.3.3.1 Products with on-site folded joints
The shape and the tolerances are to be agreed by purchaser and customer according to the application They depend especially on the technical and architectural requirements and on the folding machines and other equipment used
4.3.3.2 Products without on-site folded joints
Depending on dimensional requirements for the product, matching requirements and fabrication, values may be agreed at the time of ordering
However, if no dimensional tolerances are specified, the minimum tolerances given in Table 1 have to be met (measured without load, continuously supported, at a sample temperature of 20 °C ± 2 °C)
Table 1 — Dimensional tolerances on
products without on site folded joints
Definitions of geometrical shapes are given in 3.2 Measurements are made at 200 mm from the ends of the product, see 3.2.
4.3.4 Safety in case of fire
The requirements regarding fire are specified in EN (CEN/TC 127) and in national regulations National regulations specify the requirements regarding spread of flame for organic coatings
NOTE All products referred to in this standard are non-combustible and resistant against sparks and heat radiation.
4.3.5 Safety in use, hygiene, health and the environment
Reasonable care, in accordance with appropriate national regulations, should be taken to ensure that sheets cannot fall from the building during erection and handling, nor cause injury to the operatives hands from sharp edges No special precautions need to be taken in the handling and fixing of coated metal roof sheets
4.4 Fasteners
Fasteners shall be made from materials that give sufficient mechanical strength and have good durability Accepted materials are:
— Zinc-copper-titanium
— galvanized steel
— stainless steel (Cr-Ni)
— aluminium
— tin-plated copper
Their qualities and dimensions are determined by national Codes of Practice and/or regulations
