本规范规定了各种类型和颜色的电绝缘套管的要求，这些套管在加热时会收缩到预定尺寸。本规范包括证明符合资格要求（见第4节和第7.3节）、过程中检验和统计过程控制检验（见4.4）的规定。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 (seeSection 4and7.3), in process inspection, and statistical process control inspections (see4.4). 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.
