5.3.6 Diverters
5.3.6.1 Bath and shower
5.3.6.1.1
When tested in accordance with Clause 5.3.6.1.2, the rate of the leakage from a primary outlet when
flow is through the secondary outlet shall not exceed 400 mL/min (0.1 gpm).
5.3.6.1.2
Bath and shower diverters shall be tested for rate of leakage at 69 kPa (10 psi) flowing pressure,
measured between the diverter and the secondary outlet at 300 mm (12 in) from the diverter, with
water at 38 ± 6 °C (100 ± 10 °F). Measurements shall be taken for 5 min, beginning 1 min after the
diverter is activated.
5.3.6.2 Kitchen and lavatory
5.3.6.2.1
When tested in accordance with Clause 5.3.6.2.2, the rate of leakage out of the spout of kitchen and
lavatory side spray diverters shall not exceed 400 mL/min (0.1 gpm).
5.3.6.2.2
Kitchen and lavatory side spray diverters shall be tested for rate of leakage out of the spout at
140 ± 7 kPa (20 ± 1 psi) and 690 ± 7 kPa (100 ± 1 psi) flowing pressure with water diverted to the side
spray, using water at 10 ± 6 °C (50 ± 10 °F) and 38 ± 6 °C (100 ± 10 °F). Measurements shall be taken for
5 min, beginning 1 min after the diverter is activated.
5.3.7 Aerators and other end point devices
Aerators and other end point devices shall maintain their installed position without leakage, stripping of
threads, or loosening when tested for 5 min with water flowing at the pressures and temperatures
specified in Items b) and d) of Clause 5.3.1.4.2.
Note: Other end point devices include stream straighteners, laminar flow devices, barb fittings, and point-of-use
filters.
5.3.8 Low-pressure water dispensers
5.3.8.1 Failure criteria
Seals of low-pressure water dispensers shall not leak or otherwise fail when tested in accordance with
Clause 5.8.3.2. This test shall be conducted after the life cycle test in Clause 5.6.
5.3.8.2
The specimen shall be brought to equilibrium test temperatures by running water through it at the
manufacturer’s rated temperature and pressure. The valve shall be closed and subjected to 1.5 times
the manufacturer’s rated pressure for 5 min.
