Standard Specification for Rubber Insulating Sheeting
|Publication Date:||1 November 2018|
|ICS Code (Protective clothing):||13.340.10|
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 Three classes of sheeting, differing in electrical protection characteristics are provided and designated as Class 00, Class 0, and Class 1.
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, health, and environmental practices and determine the applicability of regulatory limitations 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.
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.

This specification covers the acceptance testing of insulating rubber sheeting that are used as a covering for the personal protection of workers from accidental contact with live electrical conductors, apparatus, or circuits. The sheeting shall be made from any elastomer or combination of elastomeric compounds of natural or synthetic origin. 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. Six classes of sheeting, designated as Classes 00, 0, 1, 2, 3, and 4, are assigned according to electrical protection characteristics. Styles of sheeting are designated in accordance to construction characteristics, namely: Style A, sheeting free of any reinforcements; and Style B, sheeting incorporated with reinforcement(s). When evaluated in accordance with the test procedures detailed herein, the sheeting shall adhere to the following property requirements: electrical properties such as phase-phase maximum use voltage, AC and DC proof-test voltages, AC and DC dielectric breakdown test voltages, and AC and DC clearances; and physical and chemical properties such as ozone resistance, moisture absorption, and oil resistance, tensile strength, tension set, elongation, drape stiffness, flex stiffness, bursting strength, low temperature resistance, tear resistance, resistance to accelerated heat aging, flame resistance, shore hardness, and puncture resistance.View Less
