23、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.
24、 1 Scope This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from Zinc-copper-titanium 1)alloy sheet with or without additional coatings. The standard establishes the general characteristics, definitions, labelling and quality c
25、ontrol 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 ma
26、de 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
27、 lengths to comply with normal service conditions. NOTEThe standard deals partly with flat products, partly with formed (prefabricated) products. Valuable information regarding preformed products is found in prEN506. Figure 1 Framework of standards 1) zinc alloyed with copper and titanium.EN501:1994

35、, 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 prEN988.
36、 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.
37、 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 p
38、roducts either in an industrial process or by an on-site process. 4.2.2 Chemical composition The chemical composition is specified in prEN988. 4.2.3 Physical and mechanical properties The physical and mechanical properties are specified in prEN988. 4.2.4 Organic coatings or chemical treatments on zi
39、nc 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) c
40、oating 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
41、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 i
42、n prEN988. 4.3.2 Dimensions and tolerances Dimensions and tolerances of sheet and coil are specified in prEN988. The minimum nominal thickness allowed for fully supported roofing products is0,6mm. 4.3.3 Shape and tolerances for formed (prefabricated) products Formed (prefabricated) products are divi
43、ded 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 preweat
44、hered surface by chemical treatmentEN501:1994 BSI 12-1999 7 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 mach
45、ines 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
46、in Table 1 have to be met (measured without load, continuously supported, at a sample temperature of20 C 2 C). Table 1 Dimensional tolerances on products without on site folded joints Definitions of geometrical shapes are given in3.2. Measurements are made at200mm from the ends of the product, see3.
47、2. 4.3.4 Safety in case of fire The requirements regarding fire are specified in EN . (CEN/TC127) and in national regulations. National regulations specify the requirements regarding spread of flame for organic coatings. NOTEAll products referred to in this standard are non-combustible and resistant
48、 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 hand
49、s 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. 5 Sampling and test methods 5.1 Flat products The sampl
