Standard Specification for Rubber Insulating Gloves
Standard Specification for Rubber Insulating Gloves
ABSTRACT This specification covers manufacturing and testing of rubber insulating gloves for protection of workers from electrical shock. Two types of gloves are provided and are designated as Type I, non-resistant to ozone, and Type II, resistant to ozone. Six classes of gloves, differing in electrical characteristics, are provided and are designated as Class 00, Class 0, Class 1, Class 2, Class 3, and Class 4. The following tests shall be performed: ac proof test; ac breakdown test; ac moisture absorption/proof test; dc proof test; dc breakdown test; ozone resistance test; chemical tests; tensile strength; tear resistance test; and puncture resistance test. SCOPE 1.1 This specification covers manufacturing and testing of rubber insulating gloves for protection of workers from electrical shock. 1.2 Two types of gloves are provided and are designated as Type I, non-resistant to ozone, and Type II, resistant to ozone. 1.3 Six classes of gloves, differing in electrical characteristics, are provided and are designated as Class 00, Class 0, Class 1, Class 2, Class 3, and Class 4. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. See IEEE/ASTM SI 10. 1.5 The following safety hazards caveat pertains only to the test method portion, Sections 16, 17, 18, and 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. For a specific warning statement, see 18.2. 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.
ASTM D120-22 is the internationally recognized standard specification for rubber insulating gloves, published by ASTM International. This standard outlines the manufacturing and testing requirements to ensure the electrical, chemical, and physical properties of rubber insulating gloves designed to protect workers from electrical shock hazards. The standard includes specific requirements for glove types and classes, as well as evaluation procedures to verify performance and safety.
The specification applies to two types of gloves: Type I (not ozone resistant) and Type II (ozone resistant). It defines six voltage classes (Class 00 through Class 4), allowing organizations to select appropriate gloves based on the electrical hazards present in their environment.
