    1. Scope

    1.1 This specification covers portable, live-line tool-supported two-pole phasing testers to be used on AC electrical systems.

    1.2 Two types of phasing testers are provided and are designated as Type I Resistive and Type II Capacitive.

    1.3 Two styles of phasing testers are provided and are designated as Style A Numerical and Style B Audible/Visual.

    1.4 The use and maintenance of these high voltage phasing testers and any necessary insulated tool handles are beyond the scope of this specification.

    1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    Note 1: Except where specified, all voltage defined in this specification refers to phase-to-phase voltage in a three-phase system. Phasing Testers covered by this specification may be used in other than three-phase systems, but the applicable phase-to-phase or phase-to-ground (earth) voltages shall be used to determine the operating voltage.

    1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
