2 when tested in accordance with EN ISO 2409; — the minimum average thickness of coating on aluminium is of grade AA5 when tested in accordance with one of the methods given in EN ISO 7599. In no cases is minimum local thickness less than 80 % of the minimum average thickness. — Compliance with the neutral salt spray (NSS) test e.g. as specified in EN ISO 9227 corrosion test in artificial atmospheres - salt spray tests with a minimum exposure time of 200 h; The defect surface area A is less than or equal to 0,1 % (A
0,1 %). The defects do not exceed a dimension of 0,3 mm. This list is not exhaustive. 4.4.3 Resistance to chemicals and stains When tested in accordance with 5.3 the glazing materials shall not show permanent staining or deterioration. 4.4.4 Resistance to wet and dry cycling When tested in accordance with 5.4, the glazing materials shall not show any cracks, crazing or discoloration. Uncoated and unpainted thermally toughened safety glass is deemed to be resistant to wet and dry cycling and need not be tested. 4.4.5 Endurance When tested in accordance with 5.5, shower enclosures shall not show any functional deterioration after 20 000 closing-opening cycles. 4.4.6 Stability When tested in accordance with 5.6, shower enclosures shall withstand an energy representing the impact of a human body on a large impact area (e.g. blow from shoulder, fall) without any functional deterioration which could result in injury to the user. 4.4.7 Water retention When tested in accordance with 5.7, shower enclosures shall retain water. A few small drops of water on the outside of the water retaining area are acceptable. Where shower enclosures are intended for installation in wet room environments (where watertightness is not required), water may temporarily pass outside the water retaining area as long as it is drained to the water retaining area. 4.5 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 !deleted text" provisions in the place of use.

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+A1:2019

Total number of particles = 16 + 53 = 69. Figure 5 — Mark and count the central fragments and add these to the perimeter count to obtain the particle count for the specimen SIST EN 14428:2015+A1:2019

Figure 6 — Examples of crack-free particles and the assessment regarding their number In the particle count, all particles wholly contained within the area of the mask shall be counted as one particle each and all the particles which are partially within the mask shall be counted as 1/2 particle each (see Figure 4). 5.1.4.2 Selection of the longest particle The longest particle shall be chosen from the body of the test specimen. It shall not be in the excluded area. 5.2 Impact behaviour of plastic sheets 5.2.1 Apparatus 5.2.1.1 Test frame, constructed of securely welded or bolted sections, designed to present a flat face to the sub-frame. 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 b
