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; c) fixed square, fixed to the reference plane surface, at least 25 mm

42、 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 depth of the rim side to be measured, one side at least 300 mm long a

43、nd 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 measured and with a diameter Dsrwith a tolerance of 0,25 mm; g) thickn

44、ess 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 with diameter Dsreach at a distance of r + 15 mm from the corners A and

45、 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 fourth spacing roller at a distance of r + 15 mm from the corner B. Me

46、asure 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. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 02/04/2010 03:56,
