5.11.2 Test procedure
5.11.2.1
The specimen shall
a) be a complete fitting;
b) be mounted in its intended operating position; and
c) have its parts tightened to the maximum torque as specified by the manufacturer.
5.11.2.2
The specimen shall be tested in accordance with ASTM B117 (neutral salt) for 96 h. After exposure, it
shall be left to dry for a minimum of 24 h at ambient laboratory conditions. The specimen shall then be
disassembled and reassembled using standard tools.
5.12 High-efficiency showerheads and hand-held showers
5.12.1 General
High-efficiency showerheads and hand-held showers shall comply with Clauses 5.12.2 to 5.12.4.
If the showerhead or hand-held shower has more than one mode, the manufacturer shall specify the
mode or modes that are intended to comply with the high-efficiency requirements.
The flow rate tests shall be conducted with water at 38 ± 6 °C (100 ± 10 °F) and the flow maintained for
at least 1 min.
5.12.2 Flow rate
5.12.2.1 Maximum
The maximum flow rate for high-efficiency showerheads and hand-held showers shall be
a) specified by the manufacturer but in no case shall be more than 7.6 L/min (2.0 gpm) at each test
pressure;
b) verified through testing at flowing pressures of 140, 310, and 550 ± 7 kPa (20, 45, and 80 ± 1 psi);
and
c) used for determining the minimum flow rates in accordance with Clause 5.12.2.2.2.
5.12.2.2 Minimum
5.12.2.2.1
If the showerhead or hand-held shower has more than one mode, the minimum flow rate shall be
determined at a flowing pressure of 310 ± 7 kPa (45 ± 1 psi) in all modes.
Pause or trickle modes designed to flow at less than 1.9 L/min (0.5 gpm) at 550 kPa (80 psi) shall be
excluded from the minimum flow requirements.
Note: The intent of this Clause is to aid in the selection of an appropriate automatic compensating valve.
