28、 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 comply with 4.8.5. NOTE These

29、 requirements are not applicable to sides or edges that are purposedly 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 accordance with A.2.3 the dev

30、iation 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 Flatness of the top su

31、rface 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 outlet hole is open, al

32、l water shall empty from the shower tray unless prevented by surface tension.
