    1. Scope

    1.1 This specification covers insulating lifting links used for protection of workers positioning a load from accidental contact of the load lifting equipment with live electrical conductors, apparatus, and circuits.

    1.2 This specification includes design, material, and testing requirements for the manufacturer and in-service inspection, testing and care requirements for the user or the agent of the user.

    1.3 Insulating links whose primary application does not pertain to power line electrical safety are not within the scope of this specification.

    1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.5 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.
