ISO 23277:2015规定了渗透检测金属焊缝表面断裂缺陷显示的验收水平。验收等级主要用于制造检验，但在适当情况下，可用于在役检验。 ISO 23277:2015中的验收水平基于使用ISO 3452系列中规定的技术和附录中建议的参数时可预期的检测能力。验收水平可能与焊接标准、应用标准、规范或规范有关。ISO 17635中显示了ISO 5817和ISO 10042的这种关系。 ISO 23277未涵盖分组显示的验收水平: 2015.

ISO 23277:2015 specifies acceptance levels for indications from surface breaking imperfections in metallic welds detected by penetrant testing. The acceptance levels are primarily intended for use during manufacture examination, but where appropriate, they can be used for in-service inspection. The acceptance levels in ISO 23277:2015 are based on detection capabilities that can be expected when using techniques specified in ISO 3452 series and parameters recommended in annex. The acceptance levels can be related to welding standards, application standards, specifications, or codes. Such a relationship is shown in ISO 17635 for ISO 5817 and ISO 10042. Acceptance levels for grouped indications are not covered by ISO 23277:2015.
