4.4 Water Resistance

Protectors/ insulators for esposed waste and supplies shall meet the waler resistance requirements contained in

para. 5.3.

4.5 Fungus Growth Resistance

Prou.”ciors/insulaton. for esposed water supply and drainpipes shall conform to the fungus growth resistance

requirements of para. 5.4.

5 PERFORMANCE REQUIREMENTS AND TEST METHODS

S.) Heat Transfer Test

Tests shall be conducted at a room temperature of 73.4°F a 3.6°F (23°C a 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 a 1.1°C) for a period ol 5 hr. A tht’rrnocouple attached to the outsidc wall of the protector/insulator

shall be used to record the temperature every 15 mm over the length of the test.

5.2 Surface Deflection and Load Test

Using a In, (12.7 mm) diameter metal rod, apply a 10 Lb (44.5 N) force at a right angle against the outside wall

of P-trap, supply stops, or riser protector br lllsec.

5.2.1 Performance Requirements. The surface shall not crack or show signs of voids. After the load is removed for5, the outside surface shall have no indentation where the load was applied.
