标准摘要
[中文适用范围]： 本文件为金属焊接接头的无损检测（NDT）方法的选择以及为质量控制目的而对检测结果进行评估提供了指导，其依据包括质量要求、材料、焊缝厚度、焊接工艺和检测范围。本文件还规定了适用于不同检测类型的通用规则和标准，用于方法的选择、检测技术及验收标准的确定。验收标准不能直接等同于ISO 5817或ISO 10042中定义的质量等级。验收标准与所生产的焊缝批次的整体质量相关。本文件中针对NDT验收标准所提出的各项要求，仅在一般层面上与ISO 5817或ISO 10042中规定的质量等级（中等、中等偏严、严格）相符，并未对每种缺陷的具体细节进行详细对应。附录A提供了针对特定检测技术的质量等级、检测等级和验收等级之间的对应关系。附录B则概述了与质量等级、验收等级和检测方法相关的特定检测技术的标准。 [外文原描述]： This document gives guidelines for the choice of non-destructive testing (NDT) methods for welds in metals and for the evaluation of the results for quality control purposes, based on quality requirements, material, weld thickness, welding process and extent of testing. This document also specifies general rules and standards to be applied to the different types of testing, for the selection of the method, the techniques and the acceptance levels. Acceptance levels cannot be a direct interpretation of the quality levels defined in ISO 5817 or ISO 10042. They are linked to the overall quality of the produced batch of welds. The requirements specified in this document for acceptance levels for NDT conform with quality levels stated in ISO 5817 or ISO 10042 (moderate, intermediate, stringent) only on a general basis and not in detail for each indication. Annex A gives correlations between quality levels, testing levels and acceptance levels for specific testing techniques. Annex B gives an overview on specific testing techniques of standards linked to quality levels, acceptance levels and testing methods.
