EN 12467:2012 (E) 4 Foreword This document (EN 12467:2012) has been prepared by Technical Committee CEN/TC 128 “Roof covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2013, and conflicting national standards shall be withdrawn at the latest by March 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12467:2004. In comparison with the previous edition, the following sections have been changed or added: 3.9, 3.10, 4, 5.1.1, 5.4.3, 5.4.4, Table 7, Table 8, 7.3.2, 7.3.2.4.2, 7.3.3.3, 7.3.3.4, 7.3.7, 7.5.2.2 and Annex C. Annex ZB concerning the EC Directive 76/769/EEC has been deleted. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. A distinction has been made between product appraisal (type tests) and factory production control requirements (acceptance tests).

5.1 General
5.1.1 Composition Sheets shall consist essentially of cement or a calcium silicate formed by a chemical reaction of a siliceous and a calcareous material, reinforced by fibres. The cement shall comply with EN 197-1 or with technical specifications relevant in the country of use. This European Standard covers fibre-reinforced cement flat sheets of type NT. The reinforcing fibres shall be one or more of the following forms: discrete elements randomly dispersed; continuous strands or tapes; nets or webs. Process aids, fillers, aggregates and pigments may be added. 5.1.2 Appearance and finish The exposed face of the sheets can be with or without texture. The sheets can be coloured or left in their natural colour. The sheets can also receive adherent coloured or uncoloured coatings on their surface. Variations of the surface appearance which do not impair the fitness for purpose of the sheets are permitted. The sheets may be supplied with holes for fixing and/or cut to size. 5.2 Classification 5.2.1 General Sheets covered by this document are divided into: four categories in accordance with their weather resistance (see 5.2.2 to 5.2.5); five classes in accordance with their bending strength (see 5.4.3); two groups of sizes in accordance with their method of installation (see 5.2.6); two levels in accordance with their dimensional tolerances (see 5.3.4). Type tests for each category are specified in Table 7. SIST EN 12467:2013
EN 12467:2012 (E) 9 5.2.2 Category A Sheets which are intended for applications where they may be subjected to heat, high moisture and severe frost. 5.2.3 Category B Sheets which are intended for applications where they may be subjected to heat, moisture and occasional frost, e.g. where they are either protected from or not subjected to severe weathering conditions. 5.2.4 Category C Sheets which are intended for internal applications, where they may be subjected to heat and moisture, but not to frost. 5.2.5 Category D Sheets for rigid underlayer applications.
5.2.6 Groups of sizes 5.2.6.1 Small size sheets Sheets for which the method of installation includes horizontal overlap. Their dimensions are generally such that their area is < 0,4 m² and have a length/width relation ≤ 3. 5.2.6.2 Large size sheets Sheets which do not correspond to indicators for small size sheets. Large sheets may be declared as "small size sheets" provided tolerances for small size sheets apply and are specified in the manufacturer's literature. 5.3 Dimensions and tolerances 5.3.1 General There are two levels of tolerances for length, width, straightness and squareness of edges. Sheets shall comply with the requirements of the same level for the four sets of tolerances. 5.3.2 Nominal length and width The manufacturer shall specify the nominal length and width of the sheets. NOTE Sheets are normally available in nominal lengths up to 3 000 mm and nominal width up to 1 250 mm. Greater nominal lengths and widths can be supplied. 5.3.3 Thickness The manufacturer shall specify the nominal thickness of the sheets. For non-textured sheets, the nominal thickness refers to the average thickness. For textured sheets, the nominal thickness refers to the maximum thickness. NOTE 1 The nominal thickness of textured sheets cannot be used for the calculation of mechanical performance. Sheets are normally available in thickness from 3 mm to 30 mm. NOTE 2 Thicker sheets can be supplied. SIST EN 12467:2013
EN 12467:2012 (E) 10 5.3.4 Tolerances on nominal dimensions1)
5.3.4.1 Tolerances on length and width Tolerances on length and width shall be in accordance with Table 1, for the appropriate level. Table 1 — Tolerances on nominal dimensions in accordance with value and level Nominal dimension aa Level I Level II a ≤ 600 mm ± 3 mm ± 4 mm 600 mm < a ≤ 1 000 mm ± 3 mm ± 5 mm 1 000 mm < a ≤ 1 600 mm ± 0,3% a ± 0,5% a 1 600 mm < a ± 5 mm ± 8 mm a a is the nominal width or length.
These tolerances are not applicable to oversize sheets. The method of measurement is given in 7.2.3.1. 5.3.4.2 Tolerances on thickness For non-textured sheets, tolerances shall be in accordance with Table 2. Table 2 — Tolerances on thickness for non-textured sheets e ≤ 6 mm ± 0,6 mm 6 mm < e ≤ 20 mm ± 10 % e e > 20 mm ± 2 mm
For sheets without texture, the maximum difference between extreme values of the thickness measurements
