5.3.2.3 Line fittings
Line fittings shall withstand a hydrostatic pressure of 3450 kPa (500 psi) for 1 min. The pressure shall be
applied to the inlet with the outlet blocked and the valve open.
5.3.3 Cross-flow check valves
Note: See Clause 4.12 for additional cross-flow requirements.
5.3.3.1 Performance requirements
When tested in accordance with Clauses 5.3.3.2 and 5.3.3.3, cross-flow check valves shall not leak more
than 35 mL/min (0.01 gpm) out of one supply inlet when the opposite supply inlet is pressurized. This
test shall be run before and after the life cycle test specified in Clause 5.6.
5.3.3.2 Set-up
Faucets or fittings that have integral flow-control devices downstream of the primary shut-off valves
that completely shut off the flow of water shall be tested with the primary shut-off valves open and all
outlets blocked.
Faucets or fittings that have devices upstream of the primary shut-off valves that might allow cross-flow
shall be tested with the primary shut-off valves closed.
5.3.3.3 Test procedure
The cross-flow check valve leak test shall be conducted as follows:
a) Pressurize one supply inlet to 35 kPa (5 psi) with water at 10 ± 6 °C (50 ± 10 °F) for 1 min with the
primary shut-off valves open and all outlets blocked.
b) Observe the opposite supply inlet for leakage.
c) Repeat Items a) and b) for the opposite supply inlet.
5.3.4 Hose assemblies
5.3.4.1 Failure criteria
Hose assemblies shall not fail or leak when tested in accordance with Clauses 5.3.4.2 and 5.3.4.3.
5.3.4.2 Torque
The threaded connections of hose assemblies shall be tested as specified in Clause 5.3.1.3 with the
threaded connections tightened to
a) the
torque required to affect the seal; and
b) 150%
of the torque required by Item a).
5.3.4.3 Burst pressure
Hose assemblies shall be tested at a hydrostatic pressure of 690 kPa (100 psi) for 1 h, followed by a
burst pressure test of 2000 kPa (290 psi) for 1 min using water at 10 ± 6 °C (50 ± 10 °F).
5.3.5 Ball joints
Showerhead, body spray, and hand-held shower assembly ball joints shall not leak in any position more
than 35 mL/min (0.01 gpm) measured over 5 min when tested at a flowing pressure of 345 ± 35 kPa (50
± 5 psi) and a temperature of 38 ± 6 °C (100 ± 10 °F).
