Standard Test Methods for Vulcanized Fibre Used for Electrical Insulation
|Publication Date:||1 January 2021|
|ICS Code (Paper and board insulating materials):||29.035.10|
1.1 These test methods cover the procedures for testing vulcanized fibre sheets, rolls, tubes, and rods of such grades as can be used for electrical insulation.
1.2 The procedures appear in the following sections:
|Bond Strength (Ply Adhesion)||16|
|Compressive Strength||12, 25, 30|
|Density||17, 26, 32|
|Dielectric Strength||18, 27|
|Dimensional Measurements||28, 33|
|Flexural Strength||13, 31|
|Tensile Strength||10, 24, 29|
|Resistance to Impact||15|
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parentheses are for information only.
1.4 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. Specific hazard statements are given in 7.3, 22.1, and 22.2.
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. Conduct comparative tests if necessary before directly comparing results of tests using the different procedures.
1.5 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.

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.View Less
