5 Requirements 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. 5.2.2 Category A Sheets which are intended for applications where they may be subjected to heat, high moisture and severe frost. SIST EN 12467:2013+A1:2016

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+A1:2016

(E) 11 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

The method of measurement is given in 7.2.3.3. These tolerances are not applicable for oversize sheets. 5.3.5.2 Squareness of edges The tolerances on squareness of sheets shall be in accordance with Table 5 for the appropriate level. Table 5 — Tolerances on squareness of edges Level I Level II 2 mm/m 4 mm/m
The method of measurement is given in 7.2.3.4. These tolerances are not applicable for oversize sheets. 5.4 Physical requirements and characteristics 5.4.1 General Mechanical and material properties are normally determined on sheets as delivered. The results shall be identified as applying to coated or uncoated material. NOTE See Annex B for statistic interpretation. 5.4.2 Apparent density The manufacturer shall specify in his literature the minimum apparent density for each category and each class of sheet. When tested in accordance with the method specified in 7.3.1, the density shall be not less than this value. 5.4.3 Moisture movement The manufacturer's literature shall state the percentage value of linear sheet moisture movement measured when the sheet is exposed to a relative humidity change from 30 % to 90 %. The stated value shall be determined in accordance with 7.3.7 using the test method given in Annex C.
2) For certain applications, tighter tolerances are demanded and should be agreed on between the manufacturer and the purchaser. SIST EN 12467:2013+A1:2016

(E) 13 5.4.4 Mechanical characteristics – Bending strength (MOR) – Modulus of elasticity (MOE) When tested as specified in 7.3.2, the minimum modulus of rupture of the sheets, expressed in megapascals, shall be as specified in Table 6. The MOR shall be the average of the values obtained from testing the samples in both directions. NOTE For non-homogeneous e.g. coated sheets, Table 6 refers to the apparent MOR. Category A and B sheet strengths are specified in the wet condition (see Table 10). Category C and D sheet strengths are specified in the ambient condition (see Table 10). The manufacturer shall specify the characteristic value for mechanical strength. Characteristic values of bending strength are based on statistical data on results of tests in ambient conditions. The statistical interpretation of test results is based on the procedure prescribed in EN 1990:2002, Eurocode — Basis of structural design, Table D.1, Vx, unknown). If a correlation has been established (see Annex B) between the MOR from production control and the MOR from products as delivered, the k-value of V x,known can be used. The minimum modulus of rupture of the sheets in the weaker direction shall be not less than 70 % of the specified value in Table 6 for the average of the two directions. This requirement does not apply to textured sheets. The modulus of elasticity of the sheets, expressed in Giga- or Megapascals, shall be specified on test results of tests in ambient conditions. The MOE shall be the average of the values obtained from testing the sampling in both directions with indication of the standard deviation. It is up to the manufacturer to determine the MOE for information purposes, i.e. with type testing. Table 6 — Minimum modulus of rupture (MOR) min. MOR in the wet condition MPa min.

NOTE For textured sheets, the MOR cannot be used for calculating mechanical performance.
5.4.5 Water impermeability for Categories A, B and D When tested in accordance with 7.3.3, traces of moisture may appear on the under face of the sheet, but in no instance shall there be any formation of drops of water. 5.4.6 Water vapour permeability for Category D For flat sheets used as rigid underlays, the water vapour resistance value
shall be determined according to 7.3.4 and shall be specified in the manufacturer's literature. The
value obtained from the test shall not be higher than the value specified by the manufacturer. SIST EN 12467:2013+A1:2016

(E) 15 5.7 Product information The manufacturer shall include the following in his literature: a) designation of the sheet: 1) type of product: NT (see 5.1.1); 2) name of the sheet; 3) category; 4) class; 5) level of tolerances. b) nominal values for: 1) thickness; 2) length and width. c) minimum apparent density; d) instructions relevant to the handling and installation. 6 !Assessment and verification of constancy of performance — AVCP 6.1 General The compliance of fibre-cement flat sheets with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by: — determination of the product type; — factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s). 6.2 Type testing 6.2.1 General Type tests shall be carried out on products as delivered. If several formats or sizes of the same category and class are being produced from the same composition and by the same production method, type tests only need to be carried out on maximum and minimum thickness. If the ratio of the maximum to minimum thickness is greater than three then an additional intermediate thickness shall be tested. All characteristics listed in Table 8 shall be subject to product type determination, except reaction to fire Class A1 without testing. The type tests relevant for each category are listed in Table 7. Product type determination shall be performed to demonstrate conformity to this standard. Tests previously performed in accordance with the provisions of this standard (same product, same characteristic(s), test method, sampling procedure, same attestation of conformity, etc.) may be taken into account. In addition, product type determination shall be performed for the approval of a new SIST EN 12467:2013+A1:2016
