Non-destructive testing of welds - General rules for metallic materials
<p>ISO 17635:2010 gives guidelines for the choice of non-destructive testing (NDT) methods for welds and evaluation of the results for quality control purposes, based on quality requirements, material, weld thickness, welding process, and extent of testing.</p>
<p>ISO 17635:2010 also specifies general rules and standards to be applied to the different types of testing, for either the methodology or the acceptance level for metallic materials.</p>
<p>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.</p>
<p>Requirements for acceptance levels for NDT comply 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.</p>
<p>One annex gives correlations between quality, NDT and acceptance level standards.</p>
<p>A second annex gives an overview of the standards linked to quality levels, acceptance levels, and NDT methods.</p>
