This specification covers the design testing of mechanical and electrical characteristics of structure-mounted insulating work platforms for electrical workers in conjunction with personal protective equipment while working on energized circuits. This shall include, but not limited to, insulating gloves with protectors or insulating and insulated hotsticks, or both and a fall protection device that does not compromise the electrical insulating protection of the platform. The platforms shall be subjected to electrical test to determine the leakage current and the ability of the specimen to withstand certain alternating-current potential without flashover between electrodes. Mechanical test shall also be conducted to allow deflection measurement under controlled loading and to determine the ability of the platform to withstand this loading without visible damages such as cracks, delamination, permanent deformation, or discoloration.

1.1 This specification covers the design testing of mechanical and electrical characteristics of structure-mounted insulating work platforms used by electrical workers.

1.2 Platforms covered by this specification are singleworker platforms not exceeding 9 ft (2.75 m) in length. Platforms designed to support more than one worker at a time are beyond the scope of this specification.

1.3 Non-insulating platforms are not within the scope of this specification.

1.4 The use and maintenance of this equipment 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 The following safety hazards caveat pertains only to the test method portion, Section 9 of this specification: 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.

1.7 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.
