本欧洲标准描述了对钎焊接头执行测试所需的无损检测程序和试件类型。所描述的非破坏性检查方法如下:a）目视检查（见第4节）; b）超声检查（见第5节）; c）放射检查（见第6节）; d）渗透检查（见第7条）; e）泄漏测试（见第8节）; f）验证测试（见第9节）; g）热成像（见第10节）。应用这些测试的钎焊接头可以是制造的测试样品，以获得钎焊接头设计数据，或者作为钎焊程序的批准测试或钎焊组件的一部分制造。每个测试描述的测试片的类型可以引用或并入处理钎焊组件的工程应用标准。本欧洲标准不建议要测试的样品数量或允许重复测试。既不指定钎焊接头的取样方法，除了对必要的预防措施给出指导外，还不对任何测试适0716用的验收标准进行评论0716。不要试图定义在任何情况下应用哪个测试或测试（如果有的话）。这是在任何parti之前要建立的事情

This European Standard describes non-destructive examination procedures and test piece types necessary to perform the tests on brazed joints. The non-destructive examination methods described are as follows: a) visual examination (see clause 4); b) ultrasonic examination (see clause 5); c) radiographic examination (see clause 6); d) penetrant examination (see clause 7); e) leak testing (see clause 8); f) proof testing (see clause 9); g) thermography (see clause 10). The brazed joints to which these tests are applied can either be test samples manufactured to obtain brazed joint design data, or manufactured as part of the approval testing of a brazing procedure, or parts of a brazed assembly. The type of test piece described for each test can be quoted or incorporated in engineering application standards that deal with brazed assemblies. This European Standard does not recommend the number of samples to be tested or the repeat tests allowed. Neither does it specify methods of sampling brazed joints, except to give guidance regarding the precautions necessary, nor does it comment on the acceptance criteria applicable to any of the tests. No attempt is made to define which test or tests, if any, should be applied in any situation. This is a matter to be established before any particular method of test is selected. The methods of non-destructive examination are not associated with any particular type of brazed assembly but lay down the general principles of the types of testing described. It is emphasised that a satisfactory examination method can only be developed and used after taking into account all the relevant factors regarding the equipment to be used and the characteristics of the test piece being examined.
