1.1 This specification covers testing of rubber insulating sheeting for use as a covering for the protection of workers from accidental contact with live electrical conductors, apparatus, or circuits. 1.2 Two types of sheeting, differing in chemical and physical characteristics, are provided and are designated as Type I, non-resistant to ozone and Type II, resistant to ozone. 1.3 Six classes of sheeting, differing in electrical protection characteristics are provided and designated as Class 00, Class 0, Class 1, Class 2, Class 3, Class 4. 1.4 Two styles of sheeting, differing in construction characteristics, are provided and are designated as Style A and Style B. 1.5 The follow safety hazards caveat applies only to the test method portion, Sections 17-19, 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 requirements prior to use. Note 1—Rubber Insulating Sheeting should remain flexible for use through normal temperature ranges. Note 2—Rubber as used in this specification is a generic term that includes elastomers and elastomeric compounds, regardless of origin.
