ÖNORM EN 12062

Based on quality requirements, material, weld thickness, welding process and extent of testing, this standard gives guidance for the choice of non-destructive testing methods of welds and evaluation of the results for quality control purposes. This standard 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. Acceptance levels cannot be a direct interpretation of the quality levels defined in EN 25817 or EN 30042. They are linked to the overall quality of the produced batch of welds. Requirements for acceptance levels for non-destructive testing comply with quality levels stated in EN 25817 or EN 30042 (moderate, indermediate, stringent), only on a general basis and not in detail for each indication. This standard can be used by application standards or by agreement between the contracting parties.
