These test methods cover the procedures for testing vulcanized fibre sheets, tubes, and rods of such grades as can be used for electrical insulation.

Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, this practice was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Реферат

These test methods details the standard procedures for testing certain properties of vulcanized fibre sheets, tubes, and rods of such grades as can be used for electrical insulation. Arc resistance, ash content, bond strength (ply adhesion), bursting strength, compressive strength, conditioning, density, dielectric strength, dimensional measurements, flammability, flexural strength, silica content, tearing strength, tensile strength, thickness (for sheets), resistance to impact, Rockwell hardness, volatile matter content, water absorption, and zinc chloride content are among the properties that these test methods shall be able to examine.

Note 1

The test methods described herein are similar technically to those described in IEC Publication 60667-2. Not all of the tests in this document are included in IEC 60667-2, and the procedures in the two publications are not completely identical; but it is expected that comparable results will be obtained from most of the procedures and comparative tests should be made if necessary before directly comparing results of tests using the different procedures.
