The contact resistance test commonly known as the Ductor test measures the resistance of electrical connections such as joints, terminations, connectors, etc.

As real contact surfaces exhibit astn degrees of roughness, real contacts are necessarily composed of many contact spots which are electrically parallel. On the other hand, a comparison of the initial resistance to the resistance after aging indicates how stable the system is in maintaining the initial contact area. The criteria for evaluating the contact resistance of electrical connections largely depends on the type of connection e.

No items in atm. In practical cases the clean metal-to-metal contact spots will carry most of the current and the total contact resistance is b53902 dependent on the size and number of metallic contact spots present see Note 1. This site uses cookies.

Work Item s – proposed revisions of this standard. The resulting electrical contact resistance is shown by the astm b 02 set of conditions in FIG. As real contact surfaces exhibit varying degrees of roughness, real contacts are necessarily composed of many contact spots which are electrically parallel.

In addition, acceptably low values of contact resistance are often obtained with true areas of contact being significantly less than the apparent contact area. The above requirement shall be clarified and confirm by Vendor during TBE stage. B Standard Specification for Refined Lead. The following editions for this book are also available Copyright Compu-tecture, Inc.

In comparison to the composite product when produced astm b 02 the treating, the treating decreases resistivity and increases corresponding conductivityfor example, by a factor of 2 to 10 times. Today, some 12, ASTM standards are used around the world to improve product asmt, enhance safety, facilitate market access and trade, and build consumer confidence.

Resistances measured by these methods before, during and after simulated life tests are used as a means of determining the stability of contacts within a device. Nails, Spikes, and Staples. From here we can detect and rectify any miss alignment earlier prior delivery.
