In addition, acceptably low values of contact resistance astm b 02 often obtained with true areas of contact being significantly less than the apparent contact area. The criteria employed in evaluating contact resistance and stability are not a part of these test methods adtm they depend on specific applications and therefore, will not be quantitatively stated.

The resulting electrical contact resistance is shown by the fourth set of conditions in FIG. As such, manufacturer recommendations need to be consulted.

However, an estimate of contact resistance 3 resulting from good metallic contact can be made for a given physical situation and used as bb539-02 comparison to actual measurements to determine how effective the system is in establishing stable metallic contact. We can resolve any miss alignment issues immediately which might occur due to design error, transportation or miss handling during installation.

For a given contact spot, when the film resistance is zero or negligible the contact resistance for that spot is nearly the same as the constriction resistance and therefore, as a practical matter, has a minimum value which represents a clean metal-to-metal contact spot.

Under all four sets of the conditions, about a 25 um wipe maintains the contact resistance below 10 milliohm at a force of gm even after exposure to high temperatures, or temperature-humidity cycles, or mixing flowing astm b The latter case was discussed in Electric B539-20 by Holm.
