In general, solutions may be reused approximately eight or ten times, or until erratic results are obtained, before discarding.

For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Explanatory Note 1. Lower the wire into the beaker until the liquid level is exactly at the b2298 mark.

From each spool approximately 12 ft 3. Referenced Documents purchase separately The documents aatm below are referenced within the subject standard but are not provided as part of the standard. NOTE 13—The equation given for the weight of the silver on the wire is for most purposes sufficiently accurate. Adjust the arm so that the wire is in the approximate center of the beaker. For specific precautionary statements see Table 1 and Explanatory Note 1.

ASTM B – Standard Specification for Silver-Coated Soft or Annealed Copper Wire

At the start of the test and until the base metal is exposed, a voltage characteristic of the plating exists across the cell; when all the plating has been removed from the test spot, this voltage changes sharply and assumes a new value which is now characteristic of the base metal. The use of these devices should be at the mutual agreement of the manufacturer and the purchaser.

This value was corrected editorially to conform with Table X1. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Explanatory Note 1.


See Table 1 for thickness of coatings for the various classes of coating and wire sizes. Attention is called also to the necessity for the use of sodium sul?

satm This abstract is a brief summary of the referenced standard. Failure to meet these requirements shall constitute failure to meet the resistivity conformance criterion. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not astmm as part of the standard. Government see S1, S2, and S3. The result will be the thickness of the plating in microinches.

However, any individual production unit, the specimen from which failed to meet the continuity criteria, shall be rejected.

Tests of soft wire made at speeds of moving head which under no-load conditions are not greater than 12 in. Link to Active This link will always route to the current Active version of the standard.

Essentially, therefore, the electronic thickness tester embodies a miniature reverse-current plating cell in which the piece to be tested is the anode and the cell itself is the cathode.

A superscript epsilon e indicates an editorial change since the last revision or reapproval.


The sample size and conformance criteria given for the various characteristics are applicable only to lots produced under these conditions. Click here to download full list of books. For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Explanatory Note 1. Tensile strength test, resistivity test, weight of coating, and dimensional measurements shall be performed to conform to the requirements specified.

This is equivalent to a resistivity value of Materials and Manufacture 4.

Make this measurement as accurately as possible. This standard does not purport to address all of the safety concerns, if any, associated with its use.


A number in parentheses indicates the year of last reapproval. The wire shall be protected against damage in ordinary handling and shipping. Active view current version of standard. Joints made after plating shall not be allowed to remain in the? Abstract This specification covers silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment.

The elongation of wire whose nominal diameter is 0. The conformance criteria for each of the prescribed properties given b98 Section 5 are as follows: Each coil shall be gaged b28 three places, one near each end and one near aastm middle.

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.

NOTE 9—It is important that the polysul? If not more than two specimens ast to meet the continuity criteria, eight additional specimens from the lot shall be tested, all of which shall conform to the continuity criteria. Therefore, the astn that the solution be tested by observing its blackening effect on a bright copper wire is signi? The manufacturer shall afford the inspector representing the purchaser all reasonable facilities to satisfy him that the material is being furnished in accordance with this speci?

Examine the specimen with the unaided eye normal spectacles excepted against a white background. Failure of a sample group from a lot to meet one or more of the following sstm shall constitute cause for rejection of the lot.
