13、ned. 3. REQUIREMENTS 3.1 Construction. The design and dimensions of the terminal block cover assembly shall be in accordance with figure 1. 3.2 Material. The terminal block cover assembly shall consist of molded thermosetting plastic in accordance with ASTM D5948, type MAI-60 or type MMI-30. 3.3 Rec
14、ycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life
15、 cycle costs. 4. VERIFICATION 4.1 Classification of inspections. The inspection requirement specified herein is classified as conformance inspection (see 4.3). 4.2 Sampling. 4.2.1 Lot. For purposes of sampling, a lot shall consist of all terminal block cover assemblies that were produced from the sa
16、me lot of thermosetting plastic compound, at the same facility, using the same equipment, practices and procedures. 4.2.2 Sampling for conformance inspection. A random sample of terminal block cover assemblies shall be selected from each lot and subjected to the inspection specified in 4.3. Sampling
17、 shall be in accordance with ASQ Z1.4, inspection level I, with the acceptance quality limit (AQL) as specified in the contract (see 6.2). 4.3 Conformance inspection. Unless otherwise specified, each of the terminal block cover assemblies selected in accordance with 4.2.2 shall be examined to verify
18、 that the design and dimensional measurements are as specified in 3.1. Any dimensions not meeting the requirements specified in 3.1 shall constitute a failure.
