Two (2) individual 200 grams samples from each batch or lot of the lithium chloride shall be sampled as specified in ASTM E300, section 25. The sample shall be tested i
21、ndependently in accordance with the applicable methods given in 4.6. If either sample fails to meet any of the test. requirements, the lot shall be rejected. The samples shall be subjected to the tests listed below: TABLE II Inspection/Requirement Defect Classification Material (see 3.1) Major Prope

23、tion equipment is required prior to its use. 4.6 Test methods and procedures (see 6.2 and 6.4). The tests to determine compliance with the requirements given in Table I shall be performed on the lithium chloride samples obtained in 4.5.1. All tests given in this section shall be performed using pres
24、cribed procedures for replicate determina- tions given in standard analytical chemistry textbooks or ASTM D2905. Also, unless otherwise specified herein, all chemicals shall be reagent grade or ACS Grade in accordance with MIL-STD-1218. 4.6.1 Purity. Carefully transfer an accurately weighed portion
25、of the sample (approximately 10 grams of the lithium chloride) to a tared weighing bottle. The weighing shall be made to the .1 mg. Care should be exercised against contamination with moisture. Record this weight. Dissolve this sample in 100 ml of distilled water and trans- fer quantitatively to a 5
