本说明书建立了对各种类型和颜色的电绝缘套管的要求，所述电绝缘套管在施加热量时将收缩到预定尺寸。本规范包括证明符合资格要求的规定（见 第4节 和 7.3 ）、过程中检查和统计过程控制检查（见 4.4 ).本规范涵盖的套管等级的连续工作温度范围为-112至+482°F（-80至+250°C）。适用的详细规范中给出了每种套管等级的连续工作温度范围。

This specification establishes the requirements for various types and colors of electrical insulating sleeving that will shrink to a predetermined size upon the application of heat. This specification includes provisions for demonstrating compliance with qualification requirements (see Section 4 and 7.3 ), in process inspection, and statistical process control inspections (see 4.4 ). The continuous operating temperature ranges for the sleeving classes covered by this specification are from -112 to +482 °F (-80 to +250 °C). The continuous operating temperature range for each sleeving class is given in the applicable detail specification.
