ASTM F2677 Standard Specification for Electrically Insulating Aprons
ASTM F2677 電氣絕緣檔板的標(biāo)準(zhǔn)規(guī)范
This specification prescribes the function and performance criteria, and acceptance testing for electrically insulating aprons for the protection of workers from incidental contact with live electrical apparatus or circuits. Three types of aprons are provided and are designated as follows: Type I, made from properly vulcanized high-grade cis-1,4-polyisoprene rubber compound of natural or synthetic origin that are non-resistant to ozone; Type II, made of any elastomer or combination of elastomeric compounds that are resistant to ozone; and Type III, made of any combination of elastomer and thermoplastic polymers that are elastic in nature and resistant to ozone. Six classes of insulating aprons, designated as Class 00, 0, 1, 2, 3, and 4, are assigned according to electrical characteristics. Aprons shall be tested for their conformance with specified chemical, physical, and electrical requirements.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers the acceptance testing of electrically insulating aprons for the protection of workers from incidental contact with live electrical apparatus or circuits.
1.2 The objective of this specification is to prescribe function and performance criteria for insulating aprons that meet a minimum level of electrically insulating and physical performance characteristics.
1.3 Three types of aprons are provided and are designated as Type I, non-resistant to ozone, Type II and Type III, resistant to ozone.
1.4 Six classes of insulating aprons, differing in electrical characteristics, are provided and are designated as Class 00, Class 0, Class 1, Class 2, Class 3, and Class 4.
