There shall be nothing retained on the 315 µm sieve. 4.7 Adhesion/cohesion When tested by the method given in 5.5, the adhesion/cohesion of the compound shall exceed 0,25 *10-6N/mm². 4.8 Dimensional stability of paper tape When tested by the method given in 5.6, the dimensional change in the length and width direction shall not be greater than 0,4 % and 2,5 % respectively. 4.9 Breaking strength of paper tape When tested by the method given in 4.7, the breaking strength shall be not less than 4,0 N per mm of tape width. 5 Test methods 5.1 Sampling A minimum of three samples shall be subjected to the tests given in this section. Only the tests relevant to the class of compound as defined in 3.11 need to be done. 5.2 Determination of setting time 5.2.1 Principle Jointing compound shall be mixed with tap water in the proportion recommended by the producer. The setting time shall be determined using a Vicat apparatus fitted with a penetration cone in an environment maintained at (23 ± 2) °C and (50 ± 5) % of relative humidity. 5.2.2 Apparatus and materials Vicat apparatus, as described in EN 196-3 with a cone of stainless steel or brass, approximately 35 mm long with a smooth polished surface and an angle of 30° ± 1°. The cone is attached to the moveable rod of the Vicat apparatus in place of the needles; waxed paper or plastic cups, at least 40 mm deep; balance, to weigh 500 g with an accuracy of 0,1 %; measuring cylinder; a beaker of 250 ml to 400 ml capacity for use as a mixing vessel; palette knife with a normal 100 mm x 20 mm flexible stainless steel blade; stop clock.
EN 13963:2005 (E) 10 5.2.3 Procedure Bring the jointing compound to a temperature of (23 ± 2) °C in a closed container before testing. Carry out the complete determination on two samples. The first sample is to determine the approximate setting time. The effective determination is carried out on the second sample. Place in the mixing vessel (beaker) the amount of tap water at (23 ± 2) °C, which will give an adequate volume of mix to enable the waxed paper or plastic cup to be struck off level without difficulty. Using the mix proportions recommended by the producer, weigh out the appropriate amount of the compound. Start the stop clock and over 10 s add the compound to the water. Allow to settle for 20 s, then mix for 30 s at a rate of 2 to 3 strokes per second in such a manner that the entire contents of the mixing vessel are thoroughly mixed. NOTE If required by the producer, re-mixing should be carried out at the stated time using the technique specified above. Transfer the mixed compound to two paper or plastic cups, strike off level and stand on a surface which is free from vibration and out of direct sunlight or draughts. Test from time to time with the Vicat apparatus, by placing the tip of the cone on the surface of the mix and allowing the moveable rod to fall freely. The distance between the points of impact of the cone shall be at least 12 mm from previous impacts and from the walls of the cup. After each penetration wipe clean the cone and re-position on the surface. As the set approaches continue the test on the second sample, avoiding over frequent penetrations since these can effect the set. Determine and record the elapsed time when the cone fails to penetrate 10 mm into the mix. A graph of penetration versus time is useful for interpolation. 5.2.4 Expression of results Report to the nearest 5 min the setting time of the compound as the elapsed time from the start of sprinkling the compound into the mixing water until the cone fails to penetrate 10 mm into the mix. NOTE Scrupulous cleanliness of the apparatus used for mixing and careful adherence to the time and energy restrictions noted in the mixing procedures are essential if repeatable results are to be obtained. Failure to eliminate unsoaked agglomerations of compound may lead to the early formation of hard lumps in the unset mass and difficulty in deciding when the set has occurred. 5.3 Determination of freedom from cracking 5.3.1 Principle A wedge of the compound shall be applied to the surface for direct decoration of a piece of gypsum plasterboard, dried and examined for cracking. For type 4 compounds a thicker wedge is necessary to simulate the conditions of use as this material is used without tapes in much thicker layers (see Figure 2). 5.3.2 Apparatus and materials - For testing type 1, 2 or 3 compounds (see Figure 1) : a) Metal rod of 2 mm diameter and 150 mm minimum length; b) broad knife, nominally 100 mm wide;

EN 13963:2005 (E) 13 5.4 Determination of freedom from coarse particles 5.4.1 Principle The mass retained on 315 µm and 200 µm sieves shall be determined. 5.4.2 Apparatus a) 315 µm and 200 µm sieves, complying with the requirements of ISO 565 and a sieve brush; b) wide-mouth bottle of approximately 1 l capacity; c) balance, accurate to 0,1 mg; d) oven capable of being maintained at a temperature of (40 ± 2) °C. 5.4.3 Procedure Prepare approximately 300 g of mixed compound in accordance with the producer's recommendations. Weigh (200 ± 5) g of mixed compound into the wide-mouthed jar and slowly add approximately 200 g of water continuously stirring to produce a thin homogeneous mix. Pour this mix through the 315 µm sieve and allow that which passes to pass on to the 200 µm sieve. Wash with water until the washings are clear. Use the sieve brush to break up any dispersible agglomerates on the surface of the sieves. Dry the sieve and any residue at (40 ± 2) °C. When dry, weigh the residue on each sieve. 5.4.4 Expression of results Report the mass of the residue retained on each sieve as a percentage of the test sample weight. 5.5 Determination of adhesion/cohesion 5.5.1 Principle The adhesion and the cohesion of a jointing compound layer shall be measured by applying a force perpendicularly to the interface (pull test). Plasterboard conforming to type A of EN 520 shall be used as background as a typical support. 5.5.2 Apparatus a) Two metal ribbons (720 mm length, 20 mm wide, 1,5 mm thick); b) piece of plasterboard conforming to type A of EN 520 cut at least 100 mm from the edge (720 mm long, 200 mm wide, 12,5 mm thick); c) taping knife (width > 200 mm); d) bowl and spatula for mixing; e) ventilated oven at 40 °C; f) metal disc (50 mm diameter, 10 to 20 mm thick) with central connection to receive traction clamp (pull head); g) adhesive with adhesion > 0,5*10-6N/mm²;
EN 13963:2005 (E) 14 h) traction device having a self centring clamp to apply a convenient tensile force; i) dynamometer or appropriate device permitting readings to 25 N; j) wooden plate (150 mm x 200 mm x 10 mm) with a circular "window" (65 mm diameter); k) thin (< 0,2 mm) double face adhesive tape. 5.5.3 Procedure Under standard laboratory conditions (23 ± 2) °C and (50 ± 5) % of relative humidity. Prepare the appropriate quantity of joint compound according to the product instructions. Place the two ribbons (a) on the face of the plasterboard (b) using the double faced adhesive (k) along each long edge. Fill uniformly with the paste avoiding bubbles. Remove excess plaster with the taping knife. Let it set and/or dry for sufficient time (according to the product instructions). Fill once more if necessary. Let it set and dry, the final drying being carried out in an oven at 40 °C to constant mass. Stick the 5 metal discs (f) to the surface of the dried jointing compound with adhesive (g) at 120 mm centres along the centre line of the board. Put the wooden plate (j) on the surface of the test sample with the 65 mm diameter window concentric to the 50 mm metal discs. Connect the pulling device to the metal disc through the "window" of the wooden plate. Apply an increasing force until failure occurs. (The increase must be constant, non stop with a value of (50 ± 5) N per second). Note the maximum tensile strength in N and the type of failure. Make five such measurements. Where test equipment cannot accept 720 mm samples, board (b) and ribbons (a) may be cut into 5 or less modules before preparing the specimens. 5.5.4 Expression of results The rupture may occur (see Figure 3): A - in the compound itself, B - at the interface between compound and board, C - in the plasterboard core, D - at the interface between compound and device, E - in the paper (not shown). State the position of the rupture. Determine the average force (F) in N of the five measured values. Calculate the adhesion or cohesion strength (R) inN/mm2 as follows: R = F/S where
S is the area of the disc in mm2. Report the adhesion R.
