ASME BPVC.CC.NC.S2-2023

Code Cases are approved exceptions or alternatives to Code rules. Theyinclude specific requirements that, when fully and correctly implemented, help users achieve continued quality and safety. Code Cases are not mandatory but may be used for Code compliance by any user. The majority of Code Cases involve new materials, but many introduce new technologies and concepts, such as nondestructive examination and welding processes, updated design and fabrication methods, and streamlined rules for inspection and quality assurance.Because of their leading-edge content and timely issuance, Code Cases can be an invaluable resource for ASME Code users.
