ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. The wire shall be protected against damage in ordinary handling and shipping.
NOTE 9—It is important that the polysul? Last previous edition approved in as B ast 99e1. Please login to your authorized staff account to use this feature. Failure of more than two specimens shall constitute failure to meet the continuity criterion.
This abstract is a brief summary of the referenced standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. See Explanatory Note 2. The silver-coated wires are classified according atsm the total weight of the coated wires, namely; Class A, B, C, D, and E. The weight of silver, in percent of the total weight of the wire, may be calculated as follows Explanatory Note Lay the wire sample on a?
However, any individual production unit, the specimen from which failed to meet the continuity criteria, shall be rejected. Adjust the arm so that the wire is in the approximate center of the beaker.
This is equivalent to a resistivity value of For specific precautionary statements see 8. There are thickness testing machines available that can be used to perform this measurement.
NOTE 13—The equation given for the weight of the silver on the wire is for most purposes sufficiently accurate. For ease of comparison, the thickness of coating for these bb298 has been included in Table 1 Explanatory Note 4. NOTE 7—In general, tested values of tensile strength are increased g298 tested values of elongation are reduced with increase of speed of the moving head of the testing machine in the tension testing of copper wire.

If there are no failures, the lot conforms to this requirement. Current edition approved May 15, The number of units in the sample 2b98 nonconformance to the requirements shall not exceed the allowable defect number, c, in Table 3.
For specific precautionary statements see Table 1 and Explanatory Note 1. When the test is complete the instrument will turn off. Tensile strength test, resistivity test, weight of coating, and dimensional measurements shall be performed to conform to the requirements specified. Allow to cool and the precipitate to settle. Each coil shall be gaged at three places, one near each end and one near the middle.
If the wire is lacquered, remove the lacquer with a solvent before testing. Failure of more than one specimen shall constitute failure to meet the weight criteria.
The result will be the n298 of the plating in microinches. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Government see S1, S2, and S3. If not more than two specimens fail to meet the continuity criteria, eight additional specimens from the lot shall be tested, all of which shall conform to the continuity criteria.
