EN 14428:2004+A1:2008 (E) 6 4.2 Cleanability When tested visually, the surfaces of the components of the shower enclosures which are accessible during use and cleaning shall be free from sharp corners, edges and burrs. When using recommended cleaning agents in accordance with the manufacturer's installation and care instructions, there shall be no reduction in safety or function of the shower enclosure. 4.3 Impact resistance/shatter properties
4.3.1 General Shower enclosures may be glazed with various materials. Where glass is used, this shall meet the requirements of 4.3.2, and where plastics materials are used, they shall meet the requirements of 4.3.3. 4.3.2 Thermally toughened safety glass Thermally toughened safety glass shall meet the requirements of EN 12150-1:2000, except in respect of Clause 8 which is replaced by 5.1 of this document. When tested in accordance with 5.1, the minimum particle count shall be 40. 4.3.3 Plastics materials When tested in accordance with 5.2, sheets shall not break or they shall break safely. 4.4 Durability 4.4.1 General Products conforming with the requirements of 4.2 and 4.3 and the following are deemed to be durable. 4.4.2 Corrosion resistance All components shall consist of corrosion-proof materials or shall be corrosion-protected. All corrosion protection shall conform with the relevant requirements specified in European and International Standards. For example:  the minimum paint adhesion performance for powder-coated or wet-painted surfaces shall comply with a cross-cut value ≤ 2 when tested in accordance with EN ISO 2409;  the minimum average thickness of coating on aluminium shall be of grade AA 8 when tested in accordance with one of the methods given in ISO 7599. In no cases shall the minimum local thickness be less than 80 % of the minimum average thickness. 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.



EN 14428:2004+A1:2008 (E) 7 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. 4.5 Dangerous substances NOTE See ZA.1 and ZA.3. 5 Test methods 5.1 Impact resistance/shatter properties 5.1.1 General The fragmentation test determines whether the glass breaks in a safe manner for a thermally toughened soda lime silicate safety glass. 5.1.2 Test specimens 5.1.2.1 Flat glass The test specimen shall have an area of (1,7 ± 0,17) m2 with a minimum length to width ration of 2:1 without holes, notches or cut-outs. 5.1.2.2 Curved glass The test specimen shall be as designed for the product. 5.1.3 Procedure The test specimen shall be impacted, using a pointed steel tool, at a position 13 mm from the longest edge of the specimen at the mid-point of that edge, until breakage occurs (see Figure 1). NOTE The fragmentation characteristics of glass are unaffected by temperatures between - 50 °C and + 100 °C. Examples of steel tools are a hammer of approximately 75 g mass, a spring loaded centre punch, or other similar appliance with a hardened point. The radius of curvature of the point should be approximately 0,2 mm. The test specimen shall be laid with the impact point flat on a table without any mechanical constraint. In order to prevent scattering of the fragments, the flat specimen shall be held at the edges, e. g. by a small frame, adhesive tape etc., the curved specimen shall be covered on its convex surface with an adhesive film so that the fragments remain interlocked after breakage yet extension of the specimen is not hindered.

Key 1 Impact point Figure 1 — Position of impact point For thermally toughened soda lime silicate safety glass manufactured by vertical toughening, the impact point shall not be on the tong mark edge. 5.1.4 Assessment of fragmentation The particle count and measuring of the dimensions of the largest particle shall be made between 4 min to 5 min after fracture. An area of radius 100 mm, centred on the impact point, and a border of 25 mm, round the edge of the test specimen (see Figure 2), shall be excluded from the assessment.
Dimensions in millimetres
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,



EN 14428:2004+A1:2008 (E) 9 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).

EN 14428:2004+A1:2008 (E) 12 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). 5.2 Impact behaviour of plastic sheets 5.2.1 Apparatus a) 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. b) 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. NOTE 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. c) 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  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.  Immediately preceding the test, condition the test pieces as follows:  temperature:
(23 ± 5) °C  duration:
24 h Place the test piece in the frame and clamp it so that the chloroprene strips are compressed by no more than 10 % to 15 % of their original thickness. When the impactor is hanging at rest, suspended from the overhead support, check that it is, at its greatest diameter, not more than 13 mm from the surface of the test piece and within 51 mm radially from the centre of the test piece (see Figure 8).  Raise the impactor to a drop height of 305 mm and steady it.



EN 14428:2004+A1:2008 (E) 13  Release the impactor so that it swings in a pendulum arc and strikes the test piece.  Inspect the test piece after impact and report whether it has remained unbroken or it has broken safely as follows: 1) Numerous cracks or fissures appear in the test piece, but no opening develops through which a 76 mm diameter sphere can be passed freely. 2) When breakage occurs which results in the production of separate fragments containing pointed protrusions, then such fragments shall be permitted provided that any pointed protrusion satisfies the following: The length of the chord between the two points which are established when an arc of radius 25 mm, whose centre is the apex of the protrusion, crosses the perimeter on each side of the apex shall be not less than 25 mm (see Figure 13).
