ASTM F2677-08a

Standard Specification for Electrically Insulating Aprons

ABSTRACT
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.
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

performed any of these tests in order to verify any manufacturer claim. Claims for failure to meet the specification are subject to
verification by the manufacturer.

4.3 Work practices vary from user to user, depending upon many factors. These factors may include, but are not limited to,
operating system voltages, design, work procedures and techniques, weather conditions, etc. Therefore, except for the restrictions
set forth in this specification because of design limitations, the use and maintenance of the equipment is beyond the scope of this
specification.
4.4 It is common practice and the responsibility of the user of this type of protective equipment to prepare complete instructions
and regulations to govern the correct and safe use of such equipment.
