Individual production units that fail to meet one or more of the requirements shall be rejected. For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Explanatory.

NOTE 1—The following speci? Originally approved in The wire shall be protected against damage in ordinary handling and shipping. These devices offer superior accuracy while performing the measurement in a variety of manners.

The more correct equation for all cases based on a density of Nails, Spikes, and Staples. For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Explanatory Note 1.

Multiply the counter readings by the factors corresponding to the size of the wire tested as listed in Table X1. Land Use and Development. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. In general, solutions may be reused approximately eight or ten times, or until erratic results are obtained, before discarding.


ASTM B298 – 12(2017)

Make this measurement as accurately as possible. The conformance criteria for each of the prescribed properties given in Section 5 are as follows: Tensile strength test, resistivity test, weight of coating, and dimensional measurements shall be performed to conform to the requirements specified. This specification covers silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment.

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.

After daily use or after a series of tests have been completed, return the test solution to a re-use storage bottle, and rinse the beaker thoroughly with water qstm dry it. For all other properties values stated in inch-pound units are to be regarded as the standard. This is equivalent to a resistivity value of The latter term means that a copper wire asym m in length and weighing 1 g would have a resistance of 0.

The result will be the thickness of the plating in microinches.

Wash free of copper salts with HNO3 wash solution, followed by two to four b928 with alcohol wash solution. The silver-coated wires are classified according to the total weight of the coated wires, namely; Class A, B, C, D, and E.

Failure of more than one specimen shall constitute failure to meet the weight criteria. Register for a trial account. 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.


Joints made after plating shall not be allowed to remain in the? Failure to meet this requirement shall constitute failure to meet the dimensional conformance criterion. The density of silver shall be taken as Enter your personal account email address to request a password reset: 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.
