EN ISO 17782:2018 (ISO 17782:2018) specifies a scheme for the conformity assessment of manufacturers of special materials used in the petroleum, petrochemical and natural gas industries. The standard defines a procedure to verify that a manufacturer has the required competence, experience, facilities and equipment to produce specified metal grades and product forms with acceptable properties as required by the purchaser (e.g., standard, material specification or material data sheet).
This document is especially applicable to high-performance metals such as duplex and high-alloy austenitic stainless steels, nickel‑based alloys, titanium and its alloys, and covers processes including induction bending and strain‑hardened products.
Key topics and technical requirements
- Conformity assessment process - steps to evaluate manufacturers and produce a Manufacturer Procedure Conformity Record (MPCR).
- Responsibilities - roles of the purchaser, manufacturer and qualifying company in the assessment process.
- Manufacturing Procedure Summary (MPS) - required content and scope describing manufacturing routes, process controls and traceability.
- Knowledge and relevant experience - evidence expectations for personnel and organization to handle specific material grades.
- Facilities and equipment - verification of foundries, heat‑treatment furnaces, thermocouples/pyrometers, quench systems and handling practices.
- Heat treatment controls - documentation, cycle description, transfer times and verification testing requirements.
- Verification of manufacturing processes - production testing, essential variables (castings, forgings, fittings, HIP, hot forming, induction bending), witnessing and reporting.
- Quality requirements - for test laboratories and manufacturers of welded products, including traceability and documentation.
- Validity and renewal - MPCR term, renewal and transitional provisions.
Practical applications and users
Who uses EN ISO 17782:2018:
- Procurement, quality and material engineers specifying and qualifying suppliers of special alloys.
- Manufacturers of duplex stainless steels, nickel alloys, titanium and components (castings, forgings, bent/strain‑hardened parts).
- Third‑party qualifying/inspection bodies conducting assessments, audits and issuing MPCRs.
- Test laboratories and welding manufacturers demonstrating compliance with purchaser requirements.
Typical uses:
- Supplier pre‑qualification and audit checklists
- Basis for contractual material acceptance and inspection plans
- Framework for verifying heat‑treatment and critical manufacturing controls
- Risk reduction for high‑integrity components in oil & gas service
Related standards and context
EN ISO 17782:2018 was prepared by ISO/TC 67 in collaboration with CEN/TC 12. It complements material specifications and testing standards used in the petroleum and natural gas industries and should be applied alongside relevant material, testing and product‑specific ISO/EN standards when defining purchaser requirements.
