16 Leakage Test
16.1 Each waste can shall be tested by the manufacturer and demonstrated to be free from leakage from the inside of the bottom to a height of not less than 6 inches (150 mm) before being shipped from the factory. No paint or similar coating shall be applied before cans are tested.
16.2 The leakage test may be made by filling the can to a depth of 6 inches (150 mm) using a test liquid having a low surface tension. comparable to that of kerosene, and a flash point well above any ambient temperature that may be encountered. The can shall be maintained in the filled condition for a period of not less than 1 minute in a position where leakage can be detected. As an alternate test, the can may be immersed, bottom down, into a tank of water to a depth that will place the outside water level not less than 6 inches (150 mm) above the inside of the bottom of the can. The interior of the can is to then be observed for evidence of leakage while the can is retained in this position for not less than 1 minute.UL 32-2019 pdf free download.
