However, in the case of heavy coatings the results obtained by the use of this equation will indicate a slightly higher percent weight than is actually present.
The silver-coated wires are classified according to the total weight of the coated wires, namely; Class A, B, C, D, and E. Tensile strength test, resistivity test, weight of coating, and dimensional measurements shall be performed to conform to the requirements specified. Link to Active This link will always route to the asmt Active version of the standard.
For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Asym Note 1.
atm NOTE 12—Principle of Operation of the Electronic Thickness Tester— The unit operates by anodically deplating a small surface area of the specimen in a cell containing the test solution.
Aatm of individual lots of less than lb of wire cannot be justi? Link to Active This link will always route to the current Active version of the standard. The wire shall be protected against damage in ordinary handling and shipping. The wire shall be bright and free from all imperfections not consistent with the b2988 commercial practice.
NOTE 2—The accuracy of the testing is reliant upon adherence to the procedures for testing that have been developed by the manufacturers as their standard test regimen. The sample size and conformance criteria given for the various characteristics are applicable only to lots produced under these conditions. Tests of soft wire made at speeds of moving head which under no-load conditions are not greater than 12 in.

ASTM B – 12() Standard Specification for Silver-Coated Soft or Annealed Copper Wire
Remember me for one month. The number of units in the sample showing nonconformance to the requirements shall not exceed the allowable defect number, c, in Table 3.
Wire whose coating weight corresponds to a thickness less than 40? The continuity of g298 coating shall be determined on representative samples taken before stranding or insulating and shall be determined by the sodium polysul?
Cool and weigh as AgCl. Boil the solution 2 to 3 min to coagulate the AgCl precipitate. The values given in parentheses are provided for information purposes only. If there are failures, but the number of these do not exceed the allowable defect number, c2 Table 2for the respective number of units in the sample, a second sample equal to n2 shall be taken and the total defects of the n plus n2 units shall not exceed the allowable defect number, c2.
No requirements for tensile strength are speci? This abstract is zstm brief summary of the referenced standard. Area at 20 The following editions for this book are also available This specification covers silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment.
From each unit, one test specimen of sufficient length shall asrm removed for b98 performance of the required test.
ASTM B – 12 Standard Specification for Silver-Coated Soft or Annealed Copper Wire
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Abstract This specification covers silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment. In the case of tests on wstm or annealed copper wire, however, the effects of speed of testing are not pronounced.
