29、l either be in accordance with the requirements of EN 251 or the manufacturer shall supply or recommend a suitable overflow fitting. 4.6 Hole edges The edges of any holes in the shower tray shall not show evidence of chips, cracks, or any other defects that may impair the appearance or performance o
30、f the shower tray. 4.7 Dimensional deviations The dimensions of shower trays shall not deviate from the size quoted by the manufacturer by greater than 5 mm. If the manufacturer states two sizes (e.g. both a work size and a nominal size) he shall state to which size the permitted deviations apply. F
31、or round shower trays, length and width correspond to the diameter. 4.8 Geometric deviations 4.8.1 General The straight sides or edges of the shower tray that might abut independent surroundings or supporting structures shall comply with the requirements of 4.8.2 to 4.8.4 and all shower trays shall
32、comply with 4.8.5. These requirements are not applicable to sides or edges that are purposely designed as curves or slopes. 4.8.2 Squaring When tested in accordance with A.2.2 the deviation from square, q, shall be less than or equal to 5 mm. 4.8.3 Straightness of the rim sides When tested in accord
33、ance with A.2.3 the deviation from straightness of the rim sides, s, shall be less than or equal to 5 mm. 4.8.4 Straightness of the bottom edge of the rim When tested in accordance with A.2.4 the deviation from straightness of the bottom edge of the rim, r, shall be less than or equal to 5 mm. 4.8.5
34、 Flatness of the top surface of rim When tested in accordance with A.2.5 the deviation from flatness of the top surface of the rim, c, shall be less than or equal to 5 mm. 4.9 Bottom of the shower tray When the shower tray is installed in accordance with the manufacturers instructions and the waste
35、outlet hole is open, all water shall empty from the shower tray unless prevented by surface tension.

A.2 Geometric deviations A.2.1 Test apparatus a) length measuring device with an accuracy of 0,5 mm; b) reference plane surface with flatness tolerance of 0,5 mm;
41、 c) fixed square, fixed to the reference plane surface, at least 25 mm deeper than the depth of the rim side to be measured, one arm at least 300 mm longer than the length to be measured and the other arm at least as long as the width to be measured; d) movable square, at least 25 mm deeper than the
42、 depth of the rim side to be measured, one side at least 300 mm long and the other side at least as long as the width to be measured; e) thickness comparator or gauge with an accuracy of 0,1 mm; f) spacing rollers made of metallic material, at least 25 mm deeper than the depth of the rim side to be
43、measured and with a diameter Dsrwith a tolerance of 0,25 mm; g) thickness wedge with a thickness of 501,0mm. A.2.2 Squaring Place the shower tray upside down on the reference plane surface as shown in Figure A.4. Position sides AB and AD adjacent to the fixed square and place three spacing rollers w
44、ith diameter Dsreach at a distance of r + 15 mm from the corners A and B, as shown in Figure A.1, where r is the radius of the corners. Measure the distance x between the corner D and the fixed square and calculate q as the difference Dsr x. Position the movable square along the side BC and place a
45、fourth spacing roller at a distance of r + 15 mm from the corner B. Measure the distance y between the corner C and the moveable square and calculate q as the difference Dsr y. Turn the shower tray through 180 and check the distances x and y at corners A and B respectively. Record the deviation. DIN
