9、4 1 Scope This standard applies to weld neck flanges for pressure vessels. General requirements for flanges are specified in DIN 28030-1. Tolerances (limit deviations) for flanges are specified in DIN 28030-2. DIN 28031 covers weld flanges for unpressurized vessels. DIN 28033 covers weld flanges for
10、 pressure vessels. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (
