    Significance and Use

    1. Scope

    1.1 This specification covers manufacturing and testing of rubber insulating sleeves for protection of workers from electrical shock.

    1.2 Two types of sleeves are provided and are designated as Type I, nonresistant to ozone, and Type II, resistant to ozone.

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

    1.4 Two styles of sleeves, differing in configuration, are provided and are designated as Style A, straight taper, and Style B, curved elbow.

    1.5 The values stated in SI units are to be regarded as the standard. See IEEE/ASTM SI 10.

    1.6 The following safety hazards caveat pertains only to the test methods portion, Sections 16 – 19, 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. Specific safety hazards statements are given in 18.2.
