The sample size shall be in accordancewith table III. Any evidence of nonconformance shall be cause for rejection,.ofthe lot. .,4.3.6 Net content packaged

32、 lot. The determination shall be applicableonly to types I and 11 packaged lots. The sample unit for this examinationshall be one filled unit container. The sample size shall be as specified intable V. The lot shall be unacceptable if the average net content perI container for all units examined is

33、less than specified.5IProvided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-8130204.3.7 Bulk lot content. The contatner shall be examined for conformanceto 5.1.1.2. If the quantity of solvent is less than the quantity specified bythe acquiring activi
