This specification defines the requirements for portable, live-line tool-supported two-pole phasing testers to be used on AC electrical systems. 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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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 and health practices and determine the applicability of regulatory limitations prior to use.
