英文名称：Brazing — Imperfections in brazed joints

发布日期：2003-12

标准范围

ISO 18279:2003详细说明了钎焊接头中可能出现的缺陷的分类。此外，还提供了有关质量水平的指南，并详细说明了缺陷的建议限值。对于本标准未涵盖的要求，应参考其他来源，例如法定法规、实施规程和技术交付条件。没有给出在个别情况下如何评估缺陷的信息，因为这取决于特定钎焊接头的要求。仅通过无损检测并不总能检测到这些缺陷。本标准仅涵盖钎焊过程中可能出现的缺陷，而不受任何额外工作负载的影响。仅涵盖此类缺陷的类型、形状和位置；没有给出发生条件或原因的指示。对于与部件特定功能相关且必不可少的钎焊接头要求，应参考相关文件，例如:。g、 制造文件或程序表。本国际标准并未规定缺陷验收水平的要求，因为这些要求会因应用情况而显著不同，但它确实建议了一些质量水平，在缺乏更详细信息的情况下，这些质量水平可能有价值。

ISO 18279:2003 details a classification of imperfections that can occur in brazing joints. In addition guidance is provided on quality levels and suggested limits for imperfections are detailed.For requirements not covered by this standard, reference is to be made to other sources, e.g. statutory regulations, codes of practice and technical delivery conditions.No information is given on how imperfections are to be assessed in individual cases because this depends on the requirements for the particular brazed joint. These imperfections are not always detectable by the use of non-destructive testing alone.The standard covers only imperfections that can occur in connection with brazing without the effect of any additional service loads. Only the type, shape and position of such imperfections are covered; no indication is given of the conditions of occurrence or causes.For requirements for brazed joints which are relevant and essential to the particular function of the component, reference should be made to the relevant documentation, e.g. manufacturing documents or procedure sheets.This International Standard does not lay down requirements for acceptance levels for imperfections since these will differ very markedly, depending on the application, but it does suggest some quality levels which may be of value in the absence of more detailed information.
