1.1 This specification covers acceptance testing of rubber insulating covers for use as portable protective devices for protection of workers from accidental contact with live electrical conductors, apparatus, or circuits. It includes insulator hoods, dead-end protectors, line hose connectors, cable end covers, and miscellaneous covers. The electrical, physical, and chemical requirements of this specification shall apply also to any new or modified styles of covers that may be developed for specific purposes.

1.2 Three types of covers, differing in chemical and physical characteristics, are provided, and are designated as Type I, non-resistant to ozone, and Type II and Type III, resistant to ozone.

1.3 Five classes of covers, differing in electrical characteristics, are provided, and are designated as Class 0, Class 1, Class 2, Class 3, and Class 4.

1.4 Five styles of covers, differing in design characteristics, are provided, and are designated as Style A, Style B, Style C, Style D, and Style E.

Note 1: Because of the use requirements some covers are semi-rigid and others flexible. The flexible devices should remain suitably flexible for application and removal through normal temperatures of − 29 to 54.5°C (−20 to 130°F).

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. See 18.2 for a specific cautionary statement.

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.
