4.5.2 Sampling inspection.

4.5.2.1 Lot formation. Unless otherwise specified (see 6.2), a lot shall consist of the minimum of the

following two quantities: all units of product (see 6.4) of the same defense PIN produced by one

manufacturer during one month; or 300 units of product of the same defense PIN.

4.5.2.2 Sampling. Unless specified otherwise in the acquisition documents (see 6.2), sampling

inspection shall consist of the tests specified in table VI. These tests shall be performed on a production

lot basis. The inspection sample shall be product selected at random from the production lot without

regard to quality and shall be of the size specified in table IX. A 4-foot length shall be cut from the end of

each sample in order to conduct the tests specified in table VI and table VII and 4.5.2.2.1. If one or more

defects are found in the inspection sample, then the production lot shall be inspected for that particular

defect and defects removed. A second inspection sample shall be selected from the production lot and

all sampling tests again performed. If one or more defective items are found in the second inspection

sample, the production lot shall be rejected and shall not be supplied to this specification.
