23、s of a number of type tests. The performance of a building element made with these products depends not only on the properties of the product as it is required by this standard, but also on the design and quality of the fabrication of the building element and on the design, construction and behaviou
24、r of the part of the building concerned in relation to the environment and conditions of use. The lead sheet supplied should be specified and used according to the National Code of Practice, depending on service conditions such as exposure to direct sunlight and the area of the piece of lead to be f
25、ixed. 1 Scope This European Standard specifies the designation, the requirements for chemical composition, surface condition and dimensional tolerances for rolled lead sheet. Lead sheet covered by this standard is made by the roll deformation process and is intended for roofs, flashings, weatherings
26、, claddings, pre-formed panels, damp-proof courses and similar building work. No requirements for supporting construction, design of roof or cladding systems and methods of joining are included. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from
27、 other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendmen
28、t or revision. For undated references the latest edition of the publication referred to applies. ISO 11014-1, Safety data sheet for chemical products Part 1: Content and order of sections. 3 Terms and definitions For the purposes of this European Standard, the following definition applies. 3.1 rolle
29、d lead sheet flat product made of lead of rectangular cross-section with uniform thickness and width supplied in coiled or flat form 4 Designation 4.1 Material number The material is designated by number (see 6.1). This material number designation is in accordance with the system given in annex A (n
30、ormative). 4.2 Product The product designation for products to this standard shall consist of: denomination (lead sheet); number of this European Standard (EN 12588); nominal thickness in millimetres. NOTEThe material number is not a part of the product designation because this standard contains onl
31、y one material. The derivation of a product designation is shown in the following example. EXAMPLE Lead sheetEN 125881,25 Denomination Number of this European Standard Nominal thickness in millimetres 5 Ordering information In order to facilitate the enquiry, order and confirmation of order procedur
32、es between the purchaser and the supplier, the purchaser shall state on his enquiry and/or order the following information: a) quantity of product required (number of pieces); b) product designation (according to 4.2); c) nominal width in millimetres; d) nominal length in metres; e) form of delivery
33、 (coiled or flat). In addition, the purchaser shall also state on the enquiry and/or order if any of the following is required: f) a declaration of conformity (see clause 8); g) special packaging; h) any other requirements.

37、ing 6 mm; width: from 100 mm up to and including 2 500 mm; length: up to and including 12 m in the coiled form. 6.2.2 Tolerances 6.2.2.1 Thickness The maximum deviation from the ordered nominal thickness, when measured in accordance with 7.1.2, shall not exceed5 %. 6.2.2.2 Width The maximum deviatio
38、n from the ordered nominal width shall not exceed5 mm. 6.2.2.3 Length The maximum deviation from the ordered nominal length shall not exceedmm. 0 +50 6.3 Surface condition The surface of the lead sheet shall be smooth, free from holes, cracks, dross inclusions and laminations. NOTELead sheet sourced
39、 from different suppliers can present a different surface appearance. 7 Test methods 7.1 Thickness 7.1.1 Apparatus Care shall be taken when measuring the thickness of lead sheet because of the softness of the material. For this reason a micrometer with a thimble ratchet and flat faced anvils of 6 mm
40、 diameter shall be used to prevent indentation into the surface of the lead. 7.1.2 Procedure The procedure shall be used to carry out measurements on flat undamaged areas, at each end of the coil or slit coil, at least 20 mm away from the edges to avoid any burrs, physical marks and creases. Three e
41、venly spaced measurements shall be carried out across the sheet and five along the sheet at 100 mm intervals. 7.2 Analysis 7.2.1 Sampling When analysis tests are required a representative sample shall be taken from the consignment and prepared into a form which is suitable for the method of analysis
42、 to be used. 7.2.2 Method The method of analysis shall be at the discretion of the supplier. In cases of dispute the method of analysis shall be agreed between the purchaser and the supplier. 8 Declaration of conformity When requested by the purchaser as an ordering requirement see 5f), the supplier
43、 shall issue a declaration of conformity to confirm that the lead sheet complies with the requirements of this standard. The form of the declaration of conformity shall be agreed between the purchaser and the supplier. 9 Marking, labelling and packaging 9.1 Marking and labelling 9.1.1 General Unless
44、 otherwise agreed at the time of ordering the following minimum requirements shall apply. Every roll and/or pack of flat sheet shall be provided with a label or print showing the following information: manufacturers name or trade mark; number of this European Standard (EN 12588); nominal dimensions
45、(length, width, thickness); identification code; mass in kilograms. Any instructions regarding handling and storage shall be clearly visible on the package.

The packaging shall never impair the quality of the product. 10 Transport, stora
48、ge and handling The products shall be dispatched and stored in conditions which protect them from humidity and condensation and shall be handled with care to maintain their quality. The products shall be stored under cover and separated from the ground by wedging which allows enough space for good v
49、entilation. Care shall be taken to avoid permanent deformation of the products during handling and storage. NOTEMoisture, in particular condensation inside the packaging can lead to the formation of stains. If there is a lengthy contact with moisture there can be further aesthetic damage to the products, particularly the formation of white staining. If this should occur advice for the removal of the stains should be sought from the supplier. 11 Safety Any risks involved in handling and use of lead are detaile
