Keep these distinctions clear
Class, PN and JIS K are separate rating systems; no automatic conversion or drilling compatibility is implied. NPS / DN is nominal, not actual OD. Similar grades are comparison candidates only. ASTM / ASME and EN designations are not automatic substitutes.
Certificates, inspection, IBR and project approvals are separate requirements. An ISO 9001 quality-system certificate is not a product approval. Current issuer editions may differ from the edition required by your contract.
