1.1 This specification covers acceptance testing of rubber insulating line hose for use as a portable protective device for protection of workers from accidental contact with live electrical conductors.
1.2 Two types of line hose 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 line hose, differing in electrical characteristics, are provided and are designated as Class 0, Class 1, Class 2, Class 3, and Class 4.
1.4 Four styles of line hose, differing in design characteristics, are provided and are designated as Style A, Style B, Style C, and Style D.Note 1-Rubber insulating line hose should remain suitably flexible for application and removal through normal working temperatures of -29 to 54.5 °C (-20 to 130°F). Note 2-Rubber as used in this specification is a generic term that includes elastomers and elastomer compounds, regardless of origin.
1.5 The following precautionary caveat pertains only to the test method portion, Sections 16, 17, 18, 19, of this specification: This standard does not purport to address all of the safety problems, 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.> For specific precautionary statements, see 18.1.1.
