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

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

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 within one sheet shall not exceed 10 % of the maximum measured value. For textured sheets, tolerances shall be in accordance with Table 3. Table 3 — Tolerances on thickness for textured sheets e ≤ 6 mm - 0,6 mm + 0,9 mm 6 mm < e ≤ 20 mm - 10 % e + 15 % e e > 20 mm - 2 mm + 3 mm
For textured sheets, the maximum difference between extreme values of the eight thickness measurements within one sheet shall not exceed 15 % of the maximum measured value. The method of measurement is given in 7.2.3.2.
1) For certain applications, tighter tolerances could be demanded. SIST EN 12467:2013

5.3.5.1 Straightness of edges Tolerances are applicable only to large size sheets. The tolerances on the straightness of edges are defined as a percentage of the length of the edge of the relevant dimensions (length or width), and shall be in accordance with Table 4 for the appropriate level. Table 4 — Tolerances on straightness of edges Level I Level II 0,1 % 0,3 %
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

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. MOR in the ambient laboratory conditions MPa Classes 1 2 3 4 5 Category A & B 4 7 13 18 24 Classes 1 2 3 4 5 Category C & D 4 7 10 16 22 Where manufacturers state minimum product MOR this should be at the 4 % acceptable quality level (AQL).
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 µ shall be determined according to 7.3.4 and shall be specified in the manufacturer's literature. SIST EN 12467:2013

When tested in accordance with 7.4.1, after 100 freeze-thaw cycles for Category A and 25 cycles for Category B and D, the ratio RL as defined in 7.4.1.4 shall be not less than 0,75. 5.5.3 Heat-rain for Categories A and B When tested in accordance with 7.4.2, after 50 heat-rain cycles for Category A and 25 cycles for Category B, any visible cracks, delamination, warping and bowing or other defects in the sheets shall not be of such a degree as to affect their performance in use. a) Water tightness is tested according to 5.4.4. b) Warping and bowing are visually assessed. 5.5.4 Warm water for Categories A, B, C and D When tested in accordance with 7.3.5, after 56 days at 60 °C, the ratio RL as defined in 7.3.5.4 shall be not less than 0,75. 5.5.5 Soak-dry for Categories A, B , C and D When tested in accordance with 7.3.6, after 50 soak-dry cycles for Category A and 25 cycles for Categories B, C and D the ratio RL as defined in 7.3.6.4 shall be not less than 0,75.
5.6 Fire and safety 5.6.1 Reaction to fire When subject to regulatory requirements, the reaction to fire of the sheets shall be declared in accordance with 7.5.
5.6.2 Release of dangerous substances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination.

Testing of mechanical characteristics is normally carried out with the upper face in compression. If required to establish a relationship between upper and under face testing where significant differences are expected or if required for design purposes, the load shall be applied on the under face. Results obtained for under face testing are not relevant for classification. Initial type testing shall be performed to demonstrate conformity to this document. Tests previously performed in accordance with the provisions of this document (same product, same characteristic(s), test method, sampling procedure, same attestation of conformity, etc.) may be taken into account. In addition, initial type testing shall be performed for the approval of a new product, a fundamental change in formulation or method of manufacture the effects of which cannot be predicted on the basis of previous experience. The results of all type tests shall be recorded and held by the manufacturer for at least five years after production of products covered by the type test has ceased. Whenever a change occurs in the fibre-cement sheet design, the raw material or supplier of components, or the production process, which would change significantly one or more of the characteristics, the type test shall be performed for the appropriate characteristic(s).

6.3 Factory production control (FPC) 6.3.1 General The manufacturer shall establish, document and maintain a FPC system to ensure that the products placed on the market conform to the stated performance characteristics. The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product. A manufacturer who has established a Quality management system according to EN ISO 9001 and made specific to the requirements of this standard, is considered to satisfy the above requirements. The results of inspections, tests or assessments requiring action shall be recorded, as shall the action(s) being taken. 6.3.2 Acceptance tests The specifications of acceptance tests apply to the product as delivered, but may be carried out at an earlier stage of maturity.
