If the jointing compound materials contain 1 % or more by weight or by volume (whichever is the more onerous) of organic material, they shall be tested and then classified in accordance with EN 13501-1. Jointing materials tested according to EN 13823 (SBI test) shall be mounted and fixed in accordance with Annex C or, when the manufacturer wishes to claim performance for a specific intended use, the mounting and fixing shall be representative of that intended use. Where subject to regulatory requirements, the air drying jointing compounds of types 1A, 2A and 3A and paper jointing tape shall either be classified without further testing according to the provisions of Annex B or it shall be tested and classified according to EN 13501-1. 4.2 Flexural strength (expressed as breaking load) Breaking load shall be measured according to test method 5.8.2 for types 1, 2 and 3 and according to test method 5.8.1 for types 4A and 4B (tapeless jointing compound). 4.3 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonized test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use.

Key 1 gypsum plasterboard 2 wedge Figure 2 — Wedge for testing type 4 compounds 5.3.3 Procedure — For testing type 1, 2 or 3 compounds: Prepare approximately 200 g of mixed compound in accordance with the manufacturer's recommendations. Position the rod on the surface for direct decoration, parallel and close to one edge of the gypsum board. Place some of the compound onto the plasterboard and next to the rod. With the broad knife spread the compound to make a wedge, 90 mm to 100 mm wide, which tapers across its width from 2 mm to zero using the rod as a thickness gauge. When spreading the mixture hold the broad knife at an angle of less than 45° to the plane of the board, and smooth the surface 2 to 4 times. Remove the rod and cut the wedge to a length of approximately 130 mm. Dry the specimen to constant mass2) at (23 ± 2) °C and (50 ± 5) % of relative humidity. Inspect the dried specimen and record the type of cracking in both the thick half and the thin half of the wedge, if any. — For testing type 4 compounds: Prepare a quantity of mixed compound depending on the number of test samples in accordance with the manufacturer's recommendations. Position the wedges on the surface for direct decoration parallel and about 40 mm apart. Place some of the compound onto the plasterboard within the wedges. With the broad knife spread the compound to fill the space between the wedges. When spreading the mixture hold the broad knife at an angle of less than 45° to the plane of the board, and smooth the surface 2 to 4 times. Dry the specimen to constant mass2) at (23 ± 2) °C and (50 ± 5) % of relative humidity.

Cut a strip of tape (250 ± 2) mm long and lay it on a flat surface. Cut two 10 mm long reference marks for the length measurement of the tape, perpendicular to the length of the tape and approximately 10 mm from each end. Measure the length down the centre line of the tape between the reference marks to the nearest 0,1 mm with the measuring device. Measure the full width of the tape in a similar manner, marking the points between which the measurement is taken. Roll up the test piece and place it in the container of water at (23 ± 2) °C so that it is entirely submerged. After 30 min remove the test piece from the water and roll it out on the flat surface and remove excessive water. Repeat the measurements of length and width immediately. 5.6.4 Expression of results Report the changes in length and width dimensions as percentages. SIST EN 13963:2014

The joint shall then be subject to a loading at a controlled rate and the loads at which the first crack and at which failure occurs shall be determined. 5.8.2.2 Apparatus A loading machine permitting readings to 1 % and capable of applying the necessary load at a rate of 250 N/min (±50 %). 5.8.2.3 Procedure For each of the three samples of jointing material, cut 10 pieces of 12,5 mm plasterboard conforming to type A of EN 520 each 200 mm × 300 mm. Joint the pieces in pairs along the long side following the manufacturer's instructions. Before jointing apply strip of adhesive tape along the back of the joint and fix carefully to battens to support the joint while the joint is made (Figure 5). Allow the specimens to dry at (23 ± 2) °C and (50 ± 5) % of relative humidity for seven days. After drying remove the battens and adhesive tape. Mount each specimen horizontally in the loading machine with the joint upwards and supported as shown in Figure 6. Apply the load continuously at a rate of 250 N/min (±125 N/min) and record the deflection and the load. SIST EN 13963:2014
