NEMA WC 56
New product
NEMA WC 56 86th Edition, January 1, 1986 3.0 kHz Insulation Continuity Proof Testing of Wire and Cable
More info
Description / Abstract:
This standard covers a general procedure for continuous voltage
proof testing of wire and cable. It is intended to apply primarily
to the final inspection of wire or cable for the purpose of finding
and eliminating defects prior to shipment or before use. The method
can also be used to eliminate defects at an early stage of
manufacturing, i.e., for wire or cable to be used in multiconductor
cables or jacketed constructions.
Because of possible damage in handling, damage caused by repeated testing, and variations in test parameters, comparison between producer's and consumer's test results are not significant.
