ISO 15156

ISO 15156:2020 is an internationally recognized standard developed by the International Organization for Standardization (ISO) that provides comprehensive guidelines on the selection and qualification of materials for use in hydrogen sulfide (H₂S)-containing environments in oil and gas production. Also known as “Materials for use in H₂S-containing environments in oil and gas production”, this standard is critical for ensuring safe operations, preventing corrosion, and avoiding equipment failures in sour service conditions.

Quality Asia Certification offers ISO 15156:2020 certification services to companies operating in oil and gas, petrochemical, and energy sectors. Our certification demonstrates your compliance with the highest levels of material safety and integrity under sour service conditions.

What is ISO 15156?

ISO 15156:2020 addresses the risk of sulfide stress cracking (SSC), hydrogen-induced cracking (HIC), and stress corrosion cracking (SCC) in metallic materials exposed to H₂S environments. The standard is divided into three parts:

  1. Part 1: General principles for selecting materials
  2. Part 2: Cracking-resistant carbon and low alloy steels
  3. Part 3: Cracking-resistant corrosion-resistant alloys (CRAs)

Certification under this standard ensures that the materials, components, and equipment you use meet global requirements for H₂S resistance in upstream oil and gas environments.

Why is ISO 15156 important?

The presence of hydrogen sulfide in oil and gas reservoirs poses a significant safety and operational risk. Equipment and materials not designed for sour service may fail prematurely, resulting in leaks, explosions, or even fatalities. ISO 15156:2020 helps prevent such risks by ensuring the right materials are selected and used correctly.

Why ISO 15156 certification is crucial:

  1. Rising global demand for H₂S safety compliance in oil and gas projects.
  2. Mandatory requirement for working with leading EPC contractors and oil majors.
  3. Enhances credibility in tenders and regulatory audits.
  4. Avoids legal liabilities and reputational damage due to material failure.


What are the benefits of ISO 15156?

  1. Global Recognition: Aligns your operations with international best practices in material integrity.
  2. Operational Safety: Minimizes risks associated with sulfide stress cracking and H₂S corrosion.
  3. Technical Compliance: Ensures material compatibility with high-pressure, high-temperature sour environments.
  4. Improved Material Lifecycle: Enhances the durability of components used in challenging operational settings.
  5. Risk Mitigation: Reduces equipment failure, downtime, and costly repairs.

What kind of businesses can benefit from ISO 15156?

  1. Increased Trust from Clients and Partners – Gain confidence of oil & gas operators, EPC firms, and regulators through certified material compliance.
  2. Reduced Operational Downtime – Prevent material failure and extend equipment service life, leading to higher uptime and productivity.
  3. Enhanced Market Access – Certification opens doors to global oil & gas projects, where ISO 15156 compliance is a pre-requisite.
  4. Legal and Regulatory Compliance – Avoid fines and sanctions with proper documentation for safety audits and regulatory inspections.
  5. Competitive Edge – Differentiate your brand in a competitive market by showcasing adherence to the latest ISO 15156:2020 standards.
  6. Sustainable Operations – Support environmental safety by minimizing leaks and failures in sour gas environments.
