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.
5.1 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.
(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.
