本文件描述了用于对桥式起重机和门式起重机的钢结构进行结构完整性评估的声发射（AE）测试技术。 本文件适用于在役桥式起重机和门式桥式起重机钢结构的测试。其他类型起重机的测试可参考本文件。 本试验方法并非用于评估桥式起重机和门式起重机结构完整性的单独NDT标准方法。 其他NDT方法用于验证和补充AT结果。 本文件未建立评估标准。

This document describes the acoustic emission (AE) testing technique used to perform structural integrity evaluation on steel structures of overhead travelling cranes and portal bridge cranes. This document applies to the testing of steel structures of in-service overhead travelling cranes and portal bridge cranes. Testing of other kinds of cranes can refer this document. This testing method is not intended to be an alone NDT standard method for the evaluation of the structural integrity of overhead travelling cranes and portal bridge cranes. Other NDT methods are used to verify and supplement the AT results. This document does not establish evaluation criteria.
