Any lot of wire, the samples of which comply with theconformance criteria of this section，shall be considered ascomplying with the requirements of Section 5. Individualproduction units that fail to meet one or more of the require-ments shall be rejected.Failure of a sample group from a lot tomeet one or more of the following criteria shall constitutecause for rejection of the lot.The conformance criteria for eachof the prescribed properties given in Section 5 are as follows:The lot shall be considered conformingif the elongation of each of the selected specimens is not lessthan the elongation value in Table 1.The electrical resistivity of each of the fourspecimens shall conform to the requirements of Table 2.Failure to meet these requirements shall constitute failure tomeet the resistivity conformance criterion of 4.2.Continuity of Coating -The continuity of the coating ofeach of the eight specimens shall conform to the requirementsof 5.4. Failure of more than two specimens shall constitutefailure to meet the continuity criterion. If not more than twospecimens fail to meet the continuity criteria, eight additionalspecimens from the lot shall be tested,all of which shallconform to the continuity criteria. However，any individualproduction unit, the specimen from which failed to meet thecontinuity criteria, shall be rejected.
Adherence of CoatingThe adherence of the coating ofeach of the eight specimens shall conform to the requirements of 5.5. Failure of more than two specimens shall constitutefailure to meet the adherence criterion.If there is failure on notmore than two, eight additional specimens from the lot shall betested, all of which shall conform to the adherence criterion.However，any individual production unit, the specimen fromwhich failed to meet the adherence criterion, shall be rejected. Weight of Coating The weight of coating of each of thefour specimens shall conform to the requirements of Failure of more than one specimen shall constitute failure tomeet the weight criteria.If only one specimen fails to meet theweight criteria, four additional specimens from the lot shall betested,all of which shall conform to the weight criteria.However，any individual production unit, the specimen fromwhich failed the weight criteria, shall be rejected.Packaging Conformance to the packaging require-ments specified by the purchaser shall be determined inaccordance with Table 4.The number of units in the sampleshowing nonconformance to the requirements shall not exceedthe allowable defect number, c, in Table 4.Failure to meet thisrequirement shall constitute failure to meet the packagingconformance criterion.ASTM B355 pdf download.
