(Specification)Standard Specification for Structure-Mounted Insulating Work Platforms for Electrical Workers
Standard Specification for Structure-Mounted Insulating Work Platforms for Electrical Workers
SCOPE
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 single- worker 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 the standard. The SI units given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
