1.1 本规范适用于电气绝缘用柔性、交联和非交联聚氯乙烯热收缩管。它以膨胀形式提供，加热时会收缩到其挤出直径。 注1: 本标准与IEC 60684–3–201相似但不完全相同。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.2.1 在某些情况下（包括标题），温度仅以摄氏度表示。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification applies to flexible, crosslinked and noncrosslinked poly(vinyl chloride) heat-shrinkable tubing for electrical insulating purposes. It is supplied in an expanded form and will shrink to its extruded diameter when heated. Note 1: This standard is similar but not identical to IEC 60684–3–201. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.2.1 In some cases (including the title), temperatures are described in degrees Celsius only. 1.3 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.
