The qual i ty confor- mance inspection samples shall consist of a sample for tests (4.3.1.2) and samples for exam

19、ination of filled containers (4.3.1.3). Samples . shall be labled completely with information identifying the purpose of the sample, name of product, manufacturers name, specification number, lot and batch number date of sampling, and contract number 4.3.1.1 Lot and batch All petrolatum manufactured

20、 as one batch shall be considered a lot and shall be numbered as such for purposes of inspection. A batch is defined as the end product of all the raw mate- rials mixed or blended in a single operation (not exceeding 24 hours) through the same processing equipment with no change in the ingredient ma

21、terials 4.3.1.2 Sample for tests. Two random containers shall be taken from each lot. A 1-pound sample shall be taken from each container and placed in separate clean, dry, metal or glass containers which shall then be sealed. Each sample shall be subjected to all the quality conformance tests (4.5.

22、1 through 4.5.31, If either sample fails any of the quality conformance inspection tests, the inspection lot shall be rejected. 4.3.1.3 Sample for examination of filled containers. A random sample of filled containers shall be selected from each lot in accor- danke with MIL-STD-105 at inspection lev

24、the packaging, pack- ing , and marklng requirements. 4.4.1 Test conditions. Test conditions shall be in accordance with 4.5 and chemical and physical values specified in section 3 apply to the average determinations made on the sample. 4.5 Methods of exami nation and test. 4.5.1 The petrolatum shall

25、 be tested in accordance with table II and 4.5.2 through 4.5.3 to determine conformance with 3.2 and examined in accordance with 4.5.4 to determine conformance with 5.1 . 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-VV-P-23bA 71 7777774 000b45L

Add 70 to 80 milliliters of precipitation naphtha conforming to ASTM D91. Immerse the tube in a wat

28、er bath at a temperature of 65“ - + 3C (1500 + 5“ F) and allow to remain with occasional shaking, until the petrolatm grease is in solution. Add precipitation naphtha to make 100 milliliters. Invert at least 20 times and proceed in accordance with ASTM method D91. 4.5.2 Abrasive material. The precip

29、itate obtained from the pre- cipitation number test (4.5.1) shall be rubbed between two smooth pieces of plate glass. The presence of abrasive materials as evidenced by a gritty feel or scratches in the glass, shall be cause for rejection of the lot represented. 4.5.3 Evaporation loss. Place five gr

30、ams of the petrolatum to be tested in a flat-bottomed brass cup of known weight and having the following dimensions: outside diameter, 1-31/32 inches; inside dia- meter, 1-29/32 inches; outside height, 1-3/16 inches; thickness of metal, 1/32 to 1/16 inch. Heat in a constant-temperature of 105“ -110C

31、 (221 O -230F) for 1 hour. Remove cup, cool to a room temperature of 25“ - t 3C (77“ t 5OF) in a dessicator, and weigh. The loss in weight shall be reported-in percent as the evaporation loss. 4.5.4 Examination of filled containers. Each sample of filled container selected in accordance with 4.3.1.3

32、 shall be examined for defects of the container and closure, for evidence of leakage and unsat- isfactory markings. Each sample container shall also be weighed to determine the amount of contents. If the number of defective containers exceeds the acceptance number of the sampl ing plan specified in

33、4.3.1.3 , the lot shall be rejected. Rejected lots may be resubmitted for reexam-.
