8.3.3 Dimensions
8.3.3.1 Length, width
Place the tested sample, on the horizontal working surface of the testing bench.
Make the one end to be tested, close to the vertical working surface. Put the
square vertically on the horizontal working surface AND close to the other end
to be tested. Then use a steel ruler, to measure the distance of two measuring
points, between the vertical working surface and the square, along the center
line, which is the length or width of the product.
8.3.3.2 Height
Place the tested end of the sample on a horizontal working surface. Place the
steel ruler close to the other tested end, in the width direction; make it parallel
to the horizontal working surface. Use a square, to measure the distance
between the horizontal working surface and the steel ruler, which is the height

point about 60°, on the basis of the last measurement position. Take the
minimum value, as the diameter of the hole; the maximum radius difference is
the roundness of the hole.
8.3.4.2 Hole center distance and centerline offset

draining exit, which is about 5 mm ~ 10 mm away from the sewage draining
exit.
8.3.5 Water seal
8.3.5.1 Water seal's depth
Add water to the pedestal pan's trap, until there is overflow. After stopping the
overflow, use a water seal ruler or ruler or an effective instrument, to measure
the vertical distance, FROM the water seal surface TO the lowest point of the
upper surface of the waterway inlet. Record it.
8.3.5.2 Water seal's surface size
Add water to the pedestal pan's trap, until there is overflow. Use a vernier caliper

product. Make the rubber surface close to the tested surface. Apply the load
vertically, so that the total load on the tested product is 0.44 kN. Keep it for 10
minutes. Observe and record whether there is any deformation or visible
structural damage.
8.7.4 Load-bearing capacity test of shower tray
The test board is steel plate, which has a diameter of 76 mm; AND a rubber
pad, which has a thickness of 13 mm, is pasted on one side.
Place the test board flat on the center of the bottom flushing surface and the
upper edge surface of the tested product. Make the rubber surface close to the
tested surface. Apply the load vertically, so that the total load on the product is
1.47 kN. Keep it for 10 minutes. Observe and record whether there is
deformation or visible structural damage.
8.8 Function test of pan and urinal
8.8.1 Functional test device
