ISO 17635:2003 PDF

Scope: This International Standard gives guidance on the selection of method(s) for non-destructive testing of fusion welds in metallic materials based on material, weld thickness, welding process, quality control requirements and extent of testing. This International Standard specifies standards to be applied to the different types of testing and general rules for either the methodology or the acceptance level for metallic materials. Trie test methods may be used alone or in combination. This International Standard also gives guidance on evaluation of the results of non-destructive testing for quality control purposes based on material, weld thickness, welding process, quality requirements application and extent of testing. This International Standard addresses non-destructive testing of completed welds. Examination and testing of parent materials prior to welding or between welding sequences is not covered. 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. Requirements for acceptance levels for non-destructive testing comply with the quality levels stated in ISO 5817 or ISO 10042 (moderate, intermediate, stringent), only on a general basis and not in detail for each indication.
