6 LOADING TEST — CLASSIFICATION AND TEST PROCEDURE
6.1 Loading Classifications
Grates and covers shall be assigned one of the following loading classifications, determined in accordance with the test procedure specified in para. 6.2:
(a) light duty: when the safe live load (see para. 6.2.3) is less than 900 kg (2,000 ib)
(b) medium duty: when the safe live load is equal to or greater than 900 kg (2,000 ib) but less than 2 250 kg (5,000 Ib)
(c) heavy duty: when the safe live load is equal to or greater than 2 250 kg (5,000 Ib) but less than 3 375 kg (7,500 lb)
(d) extra heavy duty: when the safe live load is equal to or greater than 3375 kg (7,500 ib) but less than 4 500 kg (10,000 Ib)
(e) special duty: when the safe live load is equal to or greater than 4500 kg (10,000 ib).
6.2 Test Procedure for Grate Loading
6.2.1 Test Conditions. The load shall be applied gradually to the center of the test specimen using a platen 90 mm (3.5 in.) in diameter.
6.2.2 Point of Failure. The point of failure shall be the load at which
(a) the first fracture on any part of the test specimen appears, for test specimens made of brittle materials; or
(b) the permanent set (at the point of loading) is greater than 2% of the longest transverse dimension of the test specimen, for test specimens made of ductile materials
6.2.3 Test Specimen Material Classification. Test specimens made of several materials shall be deemed made of brittle or ductile materials depending on the material of which its structural portion is made.
6.2.4 Safe Live Load. The safe live load shall be the load at the point of failure divided by two.
7 WEATHERING TEST
7.1 Test Method
Plastic drains and related components, intended for exposure to outside elements, shall be tested for weathering in accordance with ASTM G152 or ASTM G153, or in accordance with Cycle B specified in ASTM D4329 (i.e., accelerated weathering). The test specimens shall be cut from the finished product or molded from the same material used to manufacture the finished product. The test duration shall be at least 2 000 h.
