5.1 Heat Transfer
Test Tests shall be conducted at a room temperature of 73.4°F ± 3.6°F (23°C ± 2°C). One sample of each protector/insulator shall be installed on the recom- mended supply or waste assembly in accordance with the manufacturers’ instructions. Maintain the water flowing through the supplies or waste ata water temper- ature 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 pro- tector/insulator shall be used to record the temperature every 15 min over the length of the test.
NOTES: (1) If the manufacturer’s specification covers more than one size of fitting for the protector/insulators, the larger size of the fitting shall be used for testing.
(2) The temperature-measuring devices or thermocouples shall be placed on the hottest spots of the outside wall of the protector/ insulators. [Exception: Thermocouples shall be placed a mini- mum of 2 in. (50.8 mm) from the wall for supply stops.]
5.2.1 Performance Requirements. The surface shall not crack or show signs of voids. After the load is removed for 5 min, the outside surface shall have no indentation where the load was applied.
5.3.1 Method ofInspection. The surface of the sam- ple specimen shall be inspected by the unaided eye for defects and blemishes from a distance of 1 ft to 2 ft (0.3 m to 0.6 m). The light source shall be equivalent near the surface to be inspected of 150 fc ± 15 fc (1 614 lx ± 538 lx).
5.3.2 Performance Requirements. Rate each sample using the rating chart in para. 5.3. The water resistance rating shall be determined by totaling, for each test specimen, the numerical designation for each of the five gradations ofchange, then totaling the values ofall three specimens, and dividing by 3. This average shall not be over 3.
5.4 Fungus Growth
Test Three specimens of the material exposed on the out- side of the protector/insulator shall be tested in accor- dance with ASTM G21.
