MIL-DTL-27500H
4.2.1.1 Lot. A lot shall consist of all cable of a single cable designation offered for inspection at one time except that the lot
shall not exceed 1,000,000 feet or one week's production, whichever is less. The lot shall be expressed in units of thousands of feet
(total footage in lot divided by 1,000).
4.2.1.2 Sample. A sample shall consist of individual lengths of cable chosen at random from any one lot for the purpose of
inspection or test. The sample size or number of lengths to be chosen from each lot shall be determined by the sampling plan.
4.2.1.3 Sample unit. A sample unit shall consist of one of the individual lengths of the sample. Each sample unit shall be of
sufficient length to permit the performance of all applicable inspections or tests.
4.2.1.4 Specimen. A specimen shall consist of a piece of one sample unit upon which a particular inspection or test is to be
made.
4.2.1.5 Sampling A random sample of the size specified shall first be selected from the lot. A specimen of sufficient length
shall then be selected from each sample unit for the specified tests. Sampling inspection shall be in accordance with ANSI/ASQC
Z1.4, inspection level S-4, acceptance number 0 (single sampling plan).
4.2.1.6 Resubmitted inspection lots. ANSI/ASQC Z1.4 shall apply except that a resubmitted lot shall be inspected by the
contractor using tightened inspection. Before resubmitting, full particulars concerning the cause of previous rejection and the action
taken to correct the defects found in the lot shall be furnished by the contractor to the acquiring activity.
4.2.2 Process control tests. The process control tests are either of such nature that they cannot be performed on finished cable
submitted for inspection and therefore must be conducted at the most appropriate stage of manufacturing operation, or they are tests
conducted on 100 percent of the finished cable. The process control tests shall consist of the tests listed in table VIII.
