30、 the first contract or order, After the product has passed the qualification inspection (see 6.3), the tests shall be limited to the requirements of 3.4 and 3.5 and the methods of 4.7.2. Delivery of the grease shall not be delayed pending completion of testing on the first article sample by the qual

31、ifying laboratory, 4.5 Quality conformance inspection. The quality conformance inspection of the grease samples from 4.5.2 shall consist of the examinations and tests specified in table II. 4.5.1 Lot formation. A lot shall consist of all the grease produced by one manufacturer, at one plant, from th

32、e same materials and under essentially the same conditions, provided the operation is continuous and does nat exceed a 24 hour period. In the event the process is a batch operation, each batch shall constitute a lot (see 6.5). Provided by IHSNot for ResaleNo reproduction or networking permitted with

35、2. 4.6 Test conditions. Test conditions shall be in accordance with 4.7 and the physical values specified in section 3 apply to the average of determinations made on the sample. 4.7 Methods of examinations and tests. 4.7.1 Examinations. Each of the filled containers, selected in accordance with 4.5.

36、2.1, shall be examined for defects-of the container and closure, for evidence of leakage and for unsatisfactory markings to determine conformance with 5.1. Each sample container shall also be weighed to determine the amount of contents. If the number of defective containers exceeds the acceptance nu

37、mber of the sampling plan specified in 4.5.2.1, the lot shall be rejected. 4.7.2 Tests. Tests shall be performed in accordance with table ILL to determine conformance with the requirements specified in 3.4 and 3.5. 5. PACKAGING 5.1 Packaging, packing and marking.
