t 16,8 ⋅ t 43 ⋅ t GM-R t 24 ⋅ t 58 ⋅ t Additionally, no individual result shall be more than 10 % below these values. 4.1.2 Deflection under load When required and subject to regulatory requirements, the deflection under load shall be determined in accordance to the test method described in 5.7. 4.1.3 Shear strength (strength of bond/substructure connection) When the intended use of gypsum boards with mat reinforcement is stiffening building assemblies (i.e. walls, partitions, roof truss structures) the conventional shear strength of the boards shall be determined in accordance with the test method given in EN 520. NOTE This test does not measure the actual shear strength of the board but rather the strength of the board/substructure connection that is the relevant property for this application. 4.2 Fire behaviour 4.2.1 Reaction to fire When the intended use of gypsum boards with mat reinforcement is for exposed situations in building construction works, gypsum boards with mat reinforcement shall be classified in accordance with EN 13501-1. When testing the gypsum boards with mat reinforcement in the EN 13823 test according to the provisions of EN 13501-1 is required, the product shall be mounted in a manner which is representative of end use applications. The method for mounting shall be as Annex B. 4.2.2 Resistance to fire Resistance to fire is a property of an assembled system and not of a product in isolation. When required and subject to regulatory requirement, the fire resistance of a system including gypsum boards with mat reinforcement shall be classified in accordance with EN 13501-2.

When required and subject to regulatory requirement, the boards shall be tested in accordance with the method for water vapour resistance given in EN ISO 12572. 4.5 Thermal resistance (expressed as thermal conductivity) When the intended use of boards is to contribute to thermal resistance in building construction works (walls, partitions, ceilings), the tabulated values of thermal conductivity for gypsum products given in EN 12524 shall be used. When required and subject to regulatory requirement, thermal resistance shall be determined in accordance with the test method given in EN 12664. 4.6 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. 4.7 Dimensions and tolerances 4.7.1 Width NOTE Common nominal widths are: 900 mm, 1 200 mm and 1 250 mm. Other widths are also possible. The width shall be measured as described in 5.2 and compared to the nominal width. The tolerance shall be +0/ - 4 mm. 4.7.2 Length The length shall be measured as described in 5.3 and compared to the nominal length.

The thickness shall be measured as described in 5.4 and compared to the nominal thickness. Tolerances for thickness below 18 mm shall be ± 0,7 mm. For boards of thickness equal to or greater than 18 mm, the tolerance shall be ± (0,04 x thickness) (in mm). The difference between individual thickness measurements on any individual board shall not exceed 0,8 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. 4.7.5 Edge and end profiles The edge and end profiles may vary widely depending upon the jointing system and decorative and aesthetic considerations. The exception is the tapered edge and the half-rounded tapered edge profile. When measured as described in 5.6 of EN 520:2004, each individual reading shall be between the following limits:  depth of taper: between 0,6 mm and 2,5 mm;  width of taper: between 40 mm and 80 mm. 4.8 Additional requirements for gypsum boards with mat reinforcement with reduced water absorption rate Type H1 and H2 The total water absorption of boards, determined by the method described in 5.8, shall not be greater than 5 %. for type H1 and 10 % for type H2. 4.9 Additional requirements for gypsum boards with mat reinforcement with enhanced surface hardness Type 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 5.9. The diameter of the depression shall not be more than 15 mm. 4.10 Additional requirements for gypsum boards with mat reinforcement with improved core cohesion at high temperature Type F When a type F board (or combined) is subjected to the test described in 5.10 of EN 520:2004, none of the six specimens shall break.

Figure 1 — Determination of width

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 is 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 measured. Method b: The two diagonals of a board are measured. 5.5.2 Apparatus A metal rule or tape with 1 mm divisions. 5.5.3 Procedure 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.

Figure 4 — Determination of squareness of ends Method b: Measure the length (l) and the width (w) of the board and the lengths of the two diagonals d1 and d2 to the nearest mm. 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. Method b: The squareness S is expressed by the result of the expression: wlddddS.4)21(.)21(−+= (1) For the calculations, the width (w) shall be expressed in metres, all other parameters in millimetres.

5.6.1 Principle The flexural strength of boards is characterised by the flexural breaking load. Specimens 400 mm x 300 mm cut off the boards are subjected to a known load which is increased at a controlled rate until failure occurs. 5.6.2 Apparatus A loading machine capable of being read to 2 % and capable of applying the necessary load with a rate of 250 N/min ± 125 N/min. 5.6.3 Procedure 5.6.3.1 Preparation of specimens Cut two specimens from each board with all edges square (as shown in Figure 5). One specimen is taken in the longitudinal direction (designated L) and the other in the transverse direction (designated T) (see Figure 5). Cut the specimens at least 100 mm from the ends and edges of the board, except in the case of boards of less than 600 mm width where the distanc
