This set procedure may apply to any type or combination of current carrying members such as pin and socket contacts@ relay contacts@ wire and crimp connectors@ or printed circuit board and contact. Object The object of this test procedure is to detail a standard method a measure the electrical resistance of two current carrying members in mutual contact. This test procedure specifies test voltages that will not disturb insulating films on the contacting surface nor cause asperity melting. This procedure addresses the effect of thermal EMF's@ source of measurement error.
