This test is to measure the direct-current (dc) resistance of resistors, electromagnetic windings of components, and conductors. It is not intended that this test apply to the measurement of contact resistance.
When the test is performed, it is necessary to define the test temperature as the DC resistance may impact the results. DC resistance shall be measured with a resistance bridge or other suitable test equipment. The test current through the specimen shall be as small as practical considering the sensitivity of the indicating instruments, unless the test current or voltage is specified. When it is important that the temperature of the specimen shall not rise appreciably during the measurement, the test voltage shall be applied uninterruptedly for as short a time as practicable, but in no case for more than 5 seconds, unless otherwise specified. The measurement shall be made at or corrected to 25°C. The pass/fail criteria are based on the particular specification, but are typically reported in the milliohm range.
The following parameters can be altered for this test at an additional fee:
