【国外标准】 Standard Specification for Live Line and Measuring Telescoping Tools

This specification covers mechanical and electrical testing and acceptance criteria for live line and measuring telescoping tools. It shall be used for design, routine, and acceptance testing. It does not cover multiple section or extendable section clampsticks. Mechanical test methods shall include horizontal bending deflection test, free fall impact test, tension test, and vertical deflection test. Measuring device tool need not to comply with mechanical strength requirements of this specification. Electrical test methods shall include electrical design test and electrical withstand test.1.1 This specification covers mechanical and electrical testing and acceptance criteria for telescoping live line tools.1.1.1 A tool designed only for use as a measuring device need not comply with mechanical strength requirements of this specification.1.2 The use and maintenance of this equipment is beyond the scope of this specification.1.3 This specification does not cover multiple section or extendable section clampsticks.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.5 The following safety hazards caveat pertains to Section 9 only. 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.1.6 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.
