Figure — 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 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 1) zinc alloyed with copper and titanium ©

polyvinylchloride(plastisol) coating, applied by coil coating process preweathered surface by chemical treatment 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 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 © BSI 12-1999 EN 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 have to be met (measured without load, continuously supported, at a sample temperature of 20 °C ± °C) Table — Dimensional tolerances on products without on site folded joints Geometrical characteristics length (L) straightness (fs) cover width (B) depth (H) Tolerances 0/+ 10 mm mm/m length – mm/+ mm – mm/+ 1,5 mm 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
