【国外标准】 Standard Test Methods for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes

5.1 The physical and electrical properties, including break strength, elongation, dielectric strength, dissipation factor, permittivity, fusion, etc., will vary with temperature and moisture content. Control the temperature and moisture content of the sample for these test methods to yield consistent and reproducible results.1.1 These test methods cover the methods and procedures for testing electrically insulating and semi-conducting rubber tapes designed for splicing, terminating, and sheath repair of electrical wire and cable.1.2 The test methods appear in the following sections:  SectionReferenced Documents 2Conditioning 5 – 6Dielectric Strength 35 – 40Dimensions 11 – 16Dissipation Factor 22 – 26Elongation 17 – 21Heat Exposure 46 – 49Fusion 7 – 10Ozone Resistance 41 – 45Permittivity 22 – 26Sample Requirements 4Tensile Strength 17 – 21Volume Resistivity 27 – 34Ultraviolet and Weather Resistance 50 – 541.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.NOTE 1: There is no IEC equivalent to these methods.1.4 Unless otherwise stated, measurements are made on tapes from which the removable separator has been removed.1.5 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. For specific warning statement see 43.1.1.6 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.
