4.4 Water Resistance
Protectors/insulators for exposed waste and supplies shall meet the water resistance requirements contained in para. 5.3.
4.5 Fungus Growth Resistance
l’rotectors/insulators for exposed water supply and drainpipes shall conform to the fungus growth resistance requirements of para. 5.4.
5 PERFORMANCE REQUIREMENTS AND TEST METHODS
5.1 Heat Transfer Test
Tests shall be conducted at a room temperature of 73.4°F 3.6cF (23°C ± 2°C). One sample of each protector/insulator shall be installed on the recommended supply or waste assembly in accordance with the manufacturers’ instructions. Maintain the water flowing through the supplies or waste at a water temperature at 140°F ± 2°F (60°C ± 1.1°C) for a period of 5 hr. A thermocouple attached to the outside wall of the protector/insulator shall be used to record the temperature every 15 mm over the length of the test.
NOTES:
(1) If the manufacturer’s specification covers more than one size of tilling for the protector/insulators, the larger size of the filling shall be used for testing.
(2) The temperature-measuring devicv or thermocouples shall be placed on the hottest spots of the outside wall of thc protector! insubtors. (Exception: Thermocouples shall be pbccd a minimum of 2 in. (5O. mm) from the wall for supply stops.l
5.1.1 Performance Requirements. Surface temperature of the protector/msulator shall not rise above
95°F (35°C).
5.2 Surface Deflection and Load Test
Using at in. (12.7 mm) diameter metal rod, apply a 10 lb (44.5 N) force at a right angle against th outside wall of P-trap, supply siops, or riser protector for 10 sec.
5.2.1 Performance Requirements. The surface shall not crack or show signs of voids, After the load is removed for 5 mm, the outside surface shall have no indentation where the load was applied.
5.3 Water Resistance Test
Four 4 in. x 4 in. (101.6 mm X 101.6 mm) specimens are required for this test. One specimen shall be held as a controlled specimen. Three specimens shall be placed against the portholes of a suitable nonreactive vessel(see Fig.1). The portholes shall have a minimum areaof 6 in.2 (38.7 cm2) each. Use watertight connectionsbetween the tank and specimens. Cover any unusedholes with a nonreactive material. Use distilled water.Bring water temperature to 180°F 2°F(82.2℃±1.1°C),and maintain for 24 hr. The test faces of the samplesshall be submerged during testing. Rate each specimenagainst the controlled specimen for the following: blis-tering, color change, cracks, or holes.
