5.1.3.1 General
In addition to the other applicable tests and requirements specified in this Standard, two fittings shall
(a) be selected at random from a lot of five production fittings;
(b) be subjected to the test sequence specified in Clauses 5.1.3.2 and 5.1.3.3; and
(C) comply with Clauses 5.2 to 5.11.
5.1.3.2 Specimen
One of the two specimens described in Clause 5.1.3.1 shall be subjected to the following test sequence:
(a) thermal cycling (see Clause 5.3);
(b) minimum flow rate (see Clause 5.8);
(C) hydrostatic pressure (see Clause 5.9.2); and
(d) load (shower drain) (see Clause 5.5).
5.1.3.3 Specimen 2
The second of the two specimens described in Clause 5.1.3.1 shall be subjected to the following test sequence:
(a) thread torque strength (see Clause 5.9.1); and
(b) life cycle (see Clause 5.10).
Note: In this test sequence, the seals leakage test is conducted twice: once during the thread torque strength test and once during the life cycle test.
5.2.1.1 When tested in accordance with Clause 5.2.2, functional metallic parts shall not exhibit corrosion that would adversely affect the functioning of the ftting or the disassembly and reassembly of the components. Disassembly and reassembly of the functional metallic parts shall be accomplished without damage to the components or the ftting on completion of the test procedure specified in Clause 5.2.2.
5.2.2.1 Fittings shall be tested in accordance with ASTM B117 for 96 h. The specimen selected for the corrosion test shall be tested as received from the manufacturer and shall not have been subjected to any other test.
5.2.2.2 The specimen shall be assembled in accordance with the manufacturer's instructions, including the use of mounting hardware specified by the manufacturer.
5.2.2.3 The specimen shall be hung in the corrosion chamber in a position as similar as possible to the position it would be in when installed. If multiple specimens are being tested, no specimen shall be suspended above another specimen.
5.2.2.4 Immediately after the 96 h exposure period, the corrosion chamber shall be opened and the specimen shall be rinsed under running deionized water not warmer than 38 °C (100°F) and immediately dried for a minimum of 24 h at ambient laboratory conditions before inspection or attempts to disassemble. The specimen shall not be rubbed during rinsing or drying or before being examined.
5.8.1 Performance requirements The minimum flow rate for a waste fitting with all of its component parts installed shall be 27 L/min (7.0 gpm) when a sustained water head of 150 mm (6.0 in) is applied above the inlet and the outlet is open to the atmosphere.
For purposes of determining compliance with this flow rate, an observed or calculated value shall be rounded "to the nearest unit" in the last right-hand digit used in expressing the specification limit in accordance with the rounding method specified in ASTM E29.CSA B125.2 pdf download.
