This Standard specifies the classification, types and marks, technical requirements, inspection methods, inspection rules, packaging, transport and storage for phantom of maximum detectable steel thickness for industrial computed tomography (CT) testing. This Standard is applicable to type inspection and exit-factory inspection for phantom of maximum detectable steel thickness for industrial CT testing of which radian energy is 225keV and above. This Standard can also be used as the basis for acceptance of user orders.
