5.6.2.2 General parameters
5.6.2.2.1
The speed of the life cycle test apparatus shall be adjusted to 1500 ± 150 cycles of operation per hour
unless otherwise specified in this Standard or by the manufacturer.
5.6.2.2.2
Water at a flowing pressure of 345 ± 35 kPa (50 ± 5 psi) and a supply pressure of 550 kPa (80 psi)
maximum (valve closed) shall be supplied to the specimen throughout the test.
Hot water shall be at 66 ± 6 °C (150 ± 10 °F), and cold water shall be at 10 ± 6 °C (50 ± 10 °F).
5.6.2.2.3
For devices that flow in excess of 15 L/min (4.0 gpm) at 345 ± 35 kPa (50 ± 5 psi) flowing pressure, the
outlet may be restricted to a flow rate of not less than 15 L/min (4.0 gpm) during the test.
5.6.2.2.4
Fittings or valves in fittings that are intended to be used only with cold water shall be tested only with
cold water.
Fittings or valves in fittings that are intended to be used only with hot water shall be tested to the
temperature cycles specified in Clause 5.6.2.3.
5.6.2.3 Cycling
Unless otherwise specified in this Standard, fittings shall be temperature-cycled by supplying hot water
to both supplies and then supplying cold water to both supplies every 1000 volume-control cycles
(closed-open-closed).
Note: The test specified in this Clause may be started with cold water and then switched to hot water as long as
the specified sequences are maintained.
5.6.2.4 Test loads
The test apparatus shall apply a torque or force sufficient to operate the specimen throughout the test
but not exceeding 120% of the applicable torque or force specified in Table 2.
5.6.3 Fittings and other control devices
5.6.3.1 Mixing valves
Notes:
1) The
tests specified in this Clause may be started in the cold position and then switched to the hot position
as
long
as the specified sequences are maintained.
2)
The
temperature cycle from the hot open to the cold open and back to the hot open position is counted
as
one
cycle.
5.6.3.1.1
For fittings with a rotary action valve, the apparatus shall be adjusted to turn the valve and any
associated handle mechanism from the fully closed position to a position between 37% and 75% of the
fully open position, but not exceeding 360°. This test shall simulate the intended operating motion of
the fitting without making contact with the end stops, except as agreed to by the manufacturer.
