ASTM D619 Standard Test Methods for Vulcanized Fibre Used for Electrical Insulation
ASTM D619电绝缘用硫化纤维标准试验方法

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.
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.

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.
