4.4 Fixture connection loads
4.4.1 Bowl connections
4.4.1.1 Inlet connection
4.4.1.1.1 Test method. If a matching tank is not avail- able, a flat 6.35 mm (1/4 in.) steel plate 200 mm (8 in.) wide, as deep as and using the same attachment and contact points as a complementary tank, shall be attached in accordance with 4.3.1 to the normally mounted, water filled bowl. Torque shall be applied to the tank or steel plate by means of a rigidly attached vertical member and 445 ± 22 N (100 ± 5 lbs.) frontal, horizontal load, centrally located at a height of 305 mm (12 in.) above the rim (see Figure 1). The load shall remain in place for 2 ± 1/2 minutes. The bowl shall be inspected for visible damage, while the load is in place. The load shall be removed and, after inking as described in 3.3.1, shall be inspected for damage by the procedure specified in 3.2.
4.4.1.1.2 Performance requirement. There shall be no visible cracks or water leakage either when the load is in place or after removal of the load, nor any visible distortion after removal of the load.
4.4.1.2 Outlet connection
4.4.1.2.1 Test method. The bowl shall be attached as specified in 4.3. A 50 x 50 mm (2 in. x 2 in.) steel angle iron 1.37 m (54 in.) long by padded “C” clamps shall be attached under the rim of the bowl parallel to the mounting bolt cen- terline and centrally located on the rim opening. Protective padding with a thickness of 9.5 mm (0.375 in.) shall be placed between the steel angle and the fixture surface. A weight of 11.3 ± .5 kg (25 ± 1 lbs.) shall be applied vertically 610 ± 6 mm (24 ± 1/4 in.) from the center of the bowl on the previously attached angle iron as shown in Figure 2. The weight shall be set in place for 2 ± 1/2 minutes. This test shall be conducted separately on each end of the beam. The bowl shall be inspected for visible damage, while the load is in place. The load shall be removed and, after inking as described in 3.3.1, shall be inspected for damage by the procedure specified in 3.2.
4.4.1.2.2 Performance requirement. There shall be no visible cracks or water leakage either when the load is in place or after removal of the load, nor any visible distortion after removal of the load.
4.4.1.3 Seat mounting
4.4.1.3.1 Test method. The bowl shall be attached as specified in section 4.3. A specially fabricated beam shall be attached as shown in Figure 3, to the seat mounting holes using the bolts torqued to 2.71 ± .2 Nm.(24 ± 2 in. lbs). A weight of 11.3 ± 0.5 kg (25 ± 1 lbs.) shall be applied vertically 610 ± 6 mm (24 ± 1/4 in.) from the center of the bowl on the previously attached angle iron as shown in Figure 3. The weight shall be set in place for 2 ± 1/2 minutes.
