It provides two types of phasing testers, designated as Type I Resistive and Type II Capacitive, and two styles of phasing testers, designated as Style A Numerical and Style B Audible/Visual. It does not cover the use and maintenance of these high voltage phasing testers and any necessary insulated tool handles. The standard addresses ordering information for high voltage phasing testers, marking and instructions, workmanship, finish and appearance, testing, rejection and rehearing, certification, and precision and bias. Definitions of terms specific to this standard are provided, including clear indication, contact electrode, indicator, indication, insertion limit, interference field, interference ground, threshold angle, threshold voltage, and voltage range.
