Key 1 excluded area Figure 2 — Area to be excluded from the particle count determination and largest particle measurement The particle count shall be made in the region of coarsest fracture (the aim being to obtain the minimum value). The particle count shall be made by placing a mask of (50 ± 1) mm x (50 ± 1) mm on the test piece (see Figures 3, 4 and 5). The number of crack-free particles within the mask shall be counted. A particle is ‘crack-free’, if it does not contain any cracks which run from one edge to another (see Figure 6). SIST EN 14428:2015

The test frame sections and bracing members shall be steel channel 102 mm x 51 mm, or equivalent material of equal or greater strength and rigidity. This frame shall be securely bolted to the floor and securely braced as shown in Figures 7, 8 and 9. 5.2.1.2 Sub-frame, constructed of wood or other suitable material designed to hold the test piece as shown in Figure 10 so that the test piece can make contact only with the strips of chloroprene or similar material. These strips shall be capable of being compressed by 10 % to 15 % of their original depth without a permanent set being introduced. The edge cover of the chloroprene on the test pieces shall be such that for the nominal 865 mm x 1 930 mm specimens the central area of (845 ± 3) mm x (1 910 ± 3) mm is unsupported. In order to limit the compression of the chloroprene strips to within approximately 15 %, spacers of appropriate thickness and material are recommended (see Figure 10). The components of the sub-frame shall be held together, and the sub-frame shall be held to the test frame, by bolts, toggle clamps or similar fixing devices as convenient, these being uniformly spaced no more than 450 mm apart and no fewer than two per side. 5.2.1.3 Impactor, consisting of a leather case of a punch bag type, modified with a central support rod and fitting system as shown in Figure 11, and filled with chilled lead shot. The leather case shall be made from six panels, as shown in Figure 12, which shall be securely stitched together leaving a slit approximately 175 mm long to allow for filling with the lead shot. Lace holes shall be inserted on each side of the slit which is closed by a leather thong. The neck shall be taped separately to cover the worm-drive hose clamp. The complete impactor shall weigh (45 ± 0,1) kg. The impactor shall be supported as shown in Figures 7 and 8, and provision shall be made for raising the impactor to drop heights (see 5.2.2 and Figure 8) up to 1 219 mm. Prior to release it shall be supported so that the central metal rod is in line with the steel cable. The impactor shall not wobble or oscillate after its release. 5.2.2 Procedure a) Carry out the test on four test pieces. For curved sheets a sample of an unformed flat sheet of the same material shall be used. b) Immediately preceding the test, condition the test pieces as follows: SIST EN 14428:2015
