Organization: NEMA
Publication Date: 1 January 1999
Status: active
Page Count: 11
scope:

This Standards publication contains a review of the problems that have occurred when polysulfide testing has been improperly imposed on tin, silver and nickel coated copper and copper alloy stranded conductors or on tin, silver or nickel coated copper and copper alloy single or stranded conductors after insulating. The Sodium Polysulfide Test is a materials inspection test, not a finished wire or cable test, and should only be imposed on a single strand/conductor prior to stranding or insulating. A new test, called the "white card" continuity of coating test, is presented as a solution to these problems and can also be utilized on shield wires. This new test is referenced in ANSI/NEMA WC 67.
