This procedure is to define a method of detecting a discontinuity of one microsecond or longer in a mated electrical connector@ contact or socket. This procedure shall not be used for durations less than one microsecond; see EIA-364-87@ test procedure for nanosecond event detection. Definition A discontinuity is defined as a series loop resistance of 10 ohms or greater lasting for one microsecond or longer@ measured at the detector input unless otherwise specified in the referencing document.
