本标准规程涉及测试所有管道涂层，包括在用管道涂层和新涂层或替换涂层。管道涂层的高压电气检查是检测缺陷的常用方法之一。本标准介绍了目前用于管道涂层的漏涂检测仪的公认使用技术。提供了各种涂层厚度的最小测试电压表，以及测试电压、接地、涂层表面状况和设备保养的指南。

This standard practice involves testing all pipeline coatings, including coatings on in-service pipelines and new or replacement coatings. High-voltage electrical inspection of pipelines coatings is one commonly used method in the detection of defects. Presented in this standards are acknowledged techniques for the use of holiday detectors currently used on pipeline coatings. A table of minimum testing voltages for various coating thicknesses is provided, as well as guidance for testing voltages, grounding, condition of coating surfaces, and care of equipment.
