It is also equivalent, for example, to 1. Last previous edition approved in as B 49 — 98e2. Copper wire is initially given a low temperature anneal under tightly controlled conditions, subsequently wound into a spiral helical con?

This test is performed by reducing the surface oxide s to copper in an electrolytic cell. 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.


Rejection and Rehearing Number of Tests and Retests The change in length measured after the weight is removed, and the spiral has relaxed, is considered as a measure of softness. In the case of tests on soft or annealed copper rod, however, the effects of speed of testing are not pronounced.

The rod shall be free of defects, but blemishes of a nature that do not interfere with the intended application are acceptable. C, C, and C as de? The weight shall be supported initially with a platform and loaded onto the spiral uniformly and smoothly by either of two methods, namely: However, in case of dispute, astk This sample shall either be annealed or not annealed according to the following circumstances: Hardness shall be measured along the center line of the annealed specimen using the Rockwell F scale, in accordance g49 Test Method E After drawing, a coil of the wire shall be formed by winding the conductor around a mandrel having a minimum diameter of mm 7.
