Each coil shall be gaged at three places, one near each end and one near the middle. They shall be tagged or marked to correspond with the coil, spool, or reel from which they were cut. Joints made after plating shall not be allowed to remain in the? The satm correct equation for asrm cases based on a density of Inspection of individual lots of less than lb of wire cannot be justi?
Materials and Manufacture 4. The values given in parentheses are provided for information purposes only. The above named apparatus and reagent is the product of Kocour Company, So. General Requirements General Requirements 5. For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Explanatory Note 1. 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?
Keep the specimens thus cleaned wrapped in b2998 clean, dry cloth until tested. This standard does not purport to address all of the safety concerns, if any, associated with its use. The specimens shall be considered to have failed g298, by such blackening exposed copper is revealed. In general, solutions may be reused approximately eight or ten times, or until erratic results are obtained, before discarding. F Standard Specification for Driven Fasteners: Take care to avoid abrasion b928 the cut ends.
For specific precautionary statements see Table 1 and Explanatory Note 1. Make the test solution by diluting a portion of the concentrated solution with distilled water to a speci?
For continuity of coating determinations, the sample shall consist of eight production units. The wire shall be bright and free from all imperfections not consistent with the best commercial practice. If only one specimen fails to meet the weight criteria, four additional specimens from the lot shall be tested, all of which shall conform to the weight criterion.
The extent to which the solutions become exhausted depends upon the number and size of the parts tested, as well as upon the thickness of the deposits which are stripped. The continuity of the coating shall be determined on representative samples taken before stranding or insulating and shall be determined by the sodium polysul? Do not return used solutions to the original stock solution.
Conformance Criteria Explanatory Note 5 6. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The latter term means that a copper wire 1 m in length and weighing 1 g would have a resistance of 0. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The anode efficiency is further maintained by providing agitation of the solution in the test cell. This standard is subject to revision at any time by the responsible b2998 committee and must be reviewed every?
Lower the wire into the b29 until the liquid level is exactly at the crayon mark.
ASTM B – 12 Standard Specification for Silver-Coated Soft or Annealed Copper Wire
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. Cover the beaker, warm gently until solution is complete, and boil to expel brown fumes. 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. This value was corrected editorially to conform with Table X1. The cell serves as cathode and the piece to be tested is the anode.
For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Explanatory Note 1. The sample size and conformance criteria given for the various characteristics are applicable only to lots produced under these conditions. The conformance criteria for each of the prescribed properties given in Section 5 are as follows: Attention is called also to the necessity for the use of sodium sul?
For Information Only Class A, 1.
No requirements for tensile strength are speci? However, any individual production unit, the specimen from which failed the weight criteria, shall be rejected.

Please login to your authorized staff account to use this feature. Heat to boiling, remove from the hot plate, and add slowly, with rapid stirring, 10 mL of NaCl solution. If there are failures, but the number of these do not exceed the allowable defect number, astj 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.
For information purposes b289 thickness of coating in microinches provided by the percentages listed above is shown in Table 1 Explanatory Note 1.
ASTM B298 – 12(2017)
The result will be the thickness of the plating in microinches. 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.
