本标准规定了一般工业中适用于管道、容器、预跟踪和热绝缘仪表管和管道以及机械设备的电阻跟踪加热的测试、设计、安装和维护要求。电阻跟踪加热采用串联跟踪加热器、并联跟踪加热器和跟踪加热器垫或面板的形式。这些要求还包括测试标准，以确定工业应用中使用的这些微量加热装置是否适用于非机密（普通）场所。

This standard provides requirements for the testing, design, installation, and maintenance of electrical resistance trace heating in general industries as applied to pipelines, vessels, pre-traced and thermally insulated instrument tubing and piping, and mechanical equipment. The electrical resistance trace heating is in the form of series trace heaters, parallel trace heaters, and trace heater pads or panels. The requirements also include test criteria to determine the suitability of these trace heating devices utilized in industrial applications as applied in unclassified (ordinary) locations.
