Petroleum, petrochemical and natural gas industries - Scheme for conformity assessment of manufacturers of special materials (ISO 17782:2018)

This technical specification outlines a structured conformity assessment scheme specifically designed for manufacturers of special materials within the petroleum, petrochemical, and natural gas sectors. It establishes consistent criteria and procedures to evaluate the capabilities of firms producing critical components such as valves, flanges, and pipes used in demanding industrial environments. The framework ensures that material producers adhere to rigorous quality and safety requirements by defining clear pathways for certification based on international consensus. It addresses the need for reliable verification of manufacturing processes and product performance across different jurisdictions. By providing a unified approach, it facilitates the mutual recognition of assessment results and supports global trade in specialized industrial equipment. The document details the necessary audit mechanisms, competency requirements for evaluators, and the ongoing surveillance processes required to maintain certified status. It serves as a practical guide for industry stakeholders seeking to demonstrate compliance with established technical norms without relying on individual national variations. This harmonized system promotes confidence in the integrity of materials supplied to major energy infrastructure projects.
