ASTM B566-04 pdf free.Standard Specification for Copper-Clad Aluminum Wire.
Any lot of wire, the samples of which comply with the conformance criteria of this section, shall be considered as complying with the requirements of Section 6. Individual production units that fail to meet one or more of the requirements shall be rejected. Failure of a sample group from a lot to meet one or more of the following criteria shall constitute cause for rejection of the lot. The conformance criteria for each of the prescribed properties given in Section 6 are as follows:For tensile strength, clongation, resistivity, adhesion, cohesion, and dimensional measurements, the sample shall consist of a quantity of production units shown in Table 4 under heading“First Sample.” If there are no defects, the lot shall be considered as conforming to these requirements. If there are defects, but the number of these do not exceed the allowable defect number C2 (Table 4) for the respective number of units in the sample, a second sample equal to n2 shall be taken and the total defects of the n1  n2 units shall not exceed the allowable defect number C2. Failure to meet this requirement shall constitute failure to meet the conformance criterion.Tensile Strength and Elongation- The tensile strength and elongation of each of the specimens shall conform to the requirements of 6.1 and Table 1.The electrical resistivity of each of the specimens shall conform to the requirements of 6.2 and Table. Dimensions- The dimensions of each of the specimens shall conform to the requirements of Section 7.Cohesion- Cohesion of the copper cladding of each of the specimens shall conform to the requirements of 6.3.Adhesion- Adhesion of the copper cladding to the aluminum of each of the specimens shall conform to the requirements of 6.4.For surface finish and packaging (when specified by the purchaser at the time of placing the order), the sample shall consist of a quantity of production units as shown in Table 5.The number of units in the sample showing nonconformance tothe requirements shall not exceed the allowable defect numberc in Table 5. Failure to meet the requirements shall constitute
failure to meet the conformance criterion.Finish- The surface finish of each of the samples shall conform to the requirements of 8.1.ASTM B566 pdf download.
