A lot shall consist of one or more batches of Sym-di-beta-naphthylparaphenylenediamine produced by one manufacturer, in accordance with the same specification, or came Specification revision, under one continuous set of operating conditions. Each lot shall consist of that quantity
26、 of Sym-di- beta-naphthylparaphenylenediamine that has been subjected to the same unit chemical or physical process intended to make the final product homogeneous. The lot shall comply with the provisions for submisgion of product as specified in MIL-STD-105. The criteria 1 .I and procedure for the
27、assignment of lot numbers shall be in accordance with MIL-STD-1168. Also, MIL-A-48078 applies. 4.4.2 Examination. See MIL-A-48078. a. Workmanship. Examination for workmanship shall be conducted on each sample selected for testing in accordance with 4.4.3.11. if any sample fails to meet any test requ
28、irement the batch represented by the sample shall be rejected. 4.4.3 Testing. PRECAUTION: This specification covers sampling and testing of toxic and hazardous materials. . Accordingly, it is emphasized that al1 applicable safety rules, regulations and procedures must be followed in handling and pro
29、cessing the Sym-di-beta-naphthylparaphenylenediamine. 4.4.3.1 Sampling. Approximately 500 grams of the composition shall be selected from each batch to be sampled using ASTM Method E300-73 for solids. Samples shall be selected for inspection in accordance with table below. If any sample fails to mee
