When required and subject to regulatory requirements, the deflection under load shall be determined in accordance to the test method described in 5.7. The calculation of the modulus of elasticity is given in 5.7. 4.2 Fire behaviour 4.2.1 Reaction to fire When the intended use of gypsum fibre boards is for exposed situations in building construction works, the reaction to fire of gypsum fibre boards shall be classified in accordance with EN 13501-1. Testing of the gypsum fibre boards in the EN 13823 test requires the product to be mounted in a manner which is representative of end use applications. The method for mounting and fixing is given in Annex B. 4.2.2 Resistance to fire Resistance to fire is a property of an assembled system and not of the product in isolation. When required and subject to regulatory requirements, the fire resistance of a system including gypsum fibre boards shall be classified in accordance with EN 13501-2.

The difference between individual thickness measurements on any individual board shall not exceed 0,4 mm. For C2 boards: Tolerances for boards of nominal thickness below 15 mm are ± 0,5 mm. For boards of nominal thickness equal or greater than 15 mm, the tolerance is ± (0,05 × thickness) in mm. The difference between individual thickness measurements on any individual board shall not exceed 1,0 mm for a nominal thickness below 15 mm and shall not exceed (0,1 × thickness) for boards of nominal thickness equal or greater than 15 mm, 4.7.4 Squareness The deviation from squareness measured as described in 5.5 shall not exceed 2,5 mm per metre of width. 4.8 Additional requirements for gypsum fibre boards with reduced surface water absorption types GF-W1 and GF-W2 The surface water absorption of the water exposed sides of boards, determined by the method described in 5.8 shall not be greater than 300 g/m2 for Type GF-W1 and not greater than 1 500 g/m2 for Type GF-W2. 4.9 Additional requirements for gypsum fibre boards with reduced water absorption rate type GF-H The total water absorption of boards, determined by the method described in 5.9, shall not be greater than 5 %. 4.10 Additional requirements for gypsum fibre boards with enhanced density type GF-D The density of boards, determined by the method described in 5.10, shall be at least 1,4 × 103 kg/m3. 4.11 Additional requirements for gypsum fibre boards with enhanced surface hardness type GF-I The surface hardness of board is characterised by the diameter of the depression produced in the surface according to the test method described in 5.11. The diameter of the depression shall not be more than 15 mm. 4.12 Impact resistance NOTE Impact resistance is a characteristic dependent on an assembled system and not of the product in isolation. When required and subject to regulatory requirements, the impact resistance of a system including gypsum fibre board shall be determined in accordance with ISO 7892. 5 Test methods These methods shall be followed completely. Where they cannot be followed for practical reasons, deviation from the standard method shall be recorded with the results. 5.1 Sampling Testing requires three boards of each type and thickness on which tests 5.2 to 5.5 are carried out.

1) to the nearest mm, one near each end and one near the middle of the board.
Figure 1 — Determination of width 5.2.4 Expression of results Each measured value expressed in millimetres is recorded. 5.3 Determination of length 5.3.1 Principle The length is measured at three points. 5.3.2 Apparatus A metal rule or tape with reading to 1 mm divisions.

Figure 2 — Determination of length 5.3.3 Procedure Take three measurements between the extremities of the board (see Figure 2) to the nearest millimetre, one near each edge and one near the middle. 5.3.4 Expression of results Each measured value expressed in millimetres in recorded and compared to the nominal length of the board. 5.4 Determination of thickness 5.4.1 Principle The thickness of the board is measured at six points near to one end of the board. 5.4.2 Apparatus A micrometer, dial gauge, or callipers with an anvil diameter not less than 10 mm and permitting a reading to 0,05 mm. 5.4.3 Procedure Take six measurements (see Figure 3) to the nearest 0,05 mm across one end at approximately equal intervals across the width and at least 25 mm from the end and 100 mm from the edges. For boards of nominal width not greater than 600 mm, three measurements are sufficient.

Figure 3 — Determination of thickness 5.4.4 Expression of results Record each individual measurement. Record to the nearest 0,1 mm the thickness as the average of the values obtained for each board. 5.5 Determination of squareness 5.5.1 Principle Method a: Two boards are compared with each other and the squareness is measured. Method b: The two diagonals of a board are measured. 5.5.2 Apparatus A metal rule or tape with 1 mm divisions.

Figure 4 — Determination of squareness Method a: Place one board on top of another so that they coincide along one edge and at one corner (circled in Figure 4). Measure to the nearest 1 mm the distance ∆1 (see Figure 4) between the ends of the opposite edges. Turn the top board over so that the same ends coincide as for the first measurement and ensure that the corner of the top board coincides with that corner of the lower board used in the first measurement (circled in Figure 4). Measure the new distance ∆2 between the ends of the opposite edges. Method b: Measure the length (l) of the board and the lengths of the two diagonals d1 and d2 to the nearest millimetre. 5.5.4 Expression of results Method a: The squareness is characterised for one of the boards by the half sum w221∆∆+ and for other by the half difference w212∆∆+ expressed in millimetres per metre.

1) Constant mass is defined as two successive weightings 24 h apart, differing by less than 0,1 %.
