ISO 21457
ISO 21457:2020 is an international standard developed by ISO (International Organization for Standardization) that focuses on the selection of materials for equipment used in oil and gas production and processing. This standard is critical in ensuring that metallic materials are chosen with consideration for corrosion resistance, mechanical strength, and environmental compatibility. It plays a vital role in risk management and long-term asset reliability in harsh and demanding environments such as offshore platforms, subsea systems, and onshore processing facilities.
Quality Asia Certification offers ISO 21457:2020 certification services to companies involved in the design, manufacturing, and operation of equipment in oil, gas, and petrochemical industries, helping them align with international material selection requirements.

What is ISO 21457?
ISO 21457:2020 – Petroleum, petrochemical and natural gas industries — Materials selection and corrosion control for oil and gas production systems
This standard provides detailed guidance on:
- Selection of metallic materials for resistance to general and localized corrosion.
- Managing corrosion risks in hydrocarbon production and processing systems.
- Mitigation of environmental cracking risks due to hydrogen sulfide (H₂S) and other corrosive elements.
It includes updated industry practices and is harmonized with related standards like NACE MR0175/ISO 15156. The 2020 version is the most recent edition, offering the latest technical updates to address evolving industry challenges.
Why is ISO 21457 important?
With increasing exploration of oil and gas in aggressive environments, proper materials selection becomes a mission-critical aspect of design. ISO 21457:2020 provides a structured approach to ensuring that materials can withstand corrosive and high-pressure conditions.
Whether it’s a subsea wellhead, pressure vessel, or piping system, ISO 21457 ensures that materials used are vetted for strength, durability, and long-term performance, reducing failure risks and ensuring regulatory compliance.
Choosing ISO 21457 certification demonstrates a commitment to technical integrity, operational reliability, and environmental responsibility.
What are the benefits of ISO 21457?
- Corrosion Resistance Assurance: Helps identify materials suitable for corrosive production environments.
- Updated Technical Guidance: Aligns with the latest developments in metallurgy and corrosion science.
- Reduced Operational Risk: Ensures equipment longevity and reduced chances of unplanned downtime due to material failure.
- Compliance with Industry Regulations: Aligns with international norms and best practices.
- Environmental Protection: Supports sustainable operations by minimizing risk of leaks and material degradation.
What kind of businesses can benefit from ISO 21457?
By achieving ISO 21457:2020 certification, businesses operating in the energy sector can:
✅ Strengthen Asset Integrity: Enhance the reliability of pressure systems, pipelines, and structural components through effective material selection.
✅ Mitigate Corrosion Risks: Implement a preventive corrosion control strategy across operations.
✅ Reduce Maintenance Costs: Minimize the need for frequent replacements or repairs due to early material degradation.
✅ Improve Safety & Compliance: Adhere to globally recognized safety and environmental standards.
✅ Enhance Brand Credibility: Gain client and stakeholder trust through evidence of adherence to international best practices.
✅ Boost Competitive Edge: Demonstrate technical competence and proactive risk management in bidding processes.
