What ISO 29001 covers
ISO 29001 is a sector-specific quality management standard for the petroleum, petrochemical and natural gas industries. It takes the general requirements of ISO 9001 and adds the supplementary requirements that matter in a sector where the consequences of a quality failure can be severe — emphasising defect prevention and the reduction of variation and waste across the supply chain.
It applies to organisations that manufacture or supply equipment, materials and services to the oil and gas industry, where operators and major contractors expect a sector-appropriate quality system.
What certification involves
Certification is a two-stage assessment that examines your quality management system against ISO 9001 plus the oil-and-gas-specific requirements, typically including:
- The full ISO 9001 quality management foundation
- Sector-specific supplementary requirements for defect prevention
- Supplier and purchasing controls appropriate to the supply chain
- Control of production and service provision for critical products
It sits within the ISO Certifications portfolio and is, in effect, the oil-and-gas extension of ISO 9001.
Climate change: since ISO’s February 2024 climate action amendment (ISO 29001:2020/Amd 1:2024), the standard requires you to determine whether climate change is a relevant issue for your organisation, and notes that interested parties can have climate-related requirements. Certification audits include it.
How ABS helps
We prepare you for the certification audit in five steps, tailored to ISO 29001:
- Scope and gap assessment — we agree the scope of your quality management system and assess what you already have against the standard, so you know exactly what to close.
- Implementation — we help you build an ISO 9001 quality management system with the oil-and-gas supplementary requirements: defect prevention, supplier and purchasing controls, and control of production and service provision for critical products.
- Internal audit and management review — we help you run the internal audit and management review the standard requires, so the system has a record of operating before the audit.
- Readiness check — a pre-assessment, approached the way an auditor would approach it, highlights anything still to close.
- Audit support — we support you through the certification body’s Stage 1 and Stage 2 audits and help you close any findings.
Timeline & process
For most organisations, ISO 29001 certification takes around 12–16 weeks, depending on the complexity of products and processes in scope and whether ISO 9001 is already in place. Each engagement begins with a fixed-price scoping call and a proposal within 24 hours.
Common questions
Who needs ISO 29001?
Organisations in the petroleum, petrochemical and natural gas supply chain — manufacturers and suppliers of equipment, materials and services — particularly where operators and major contractors require a sector-specific quality system.
How is ISO 29001 different from ISO 9001?
ISO 29001 builds on ISO 9001 and adds sector-specific requirements for the oil and gas industry, with particular emphasis on defect prevention and the reduction of variation and waste in the supply chain.
How long does ISO 29001 certification take?
For most organisations, ISO 29001 certification takes around 12–16 weeks, depending on the complexity of products and processes in scope and whether ISO 9001 is already in place.
What does ABS do, and what does the certification body do?
ABS prepares you for certification: we agree the scope of your quality management system, assess the gaps, help you implement it, support your internal audit and management review, check readiness and support you through the audits. The certification body, an independent, accredited organisation you choose, carries out the Stage 1, Stage 2 and surveillance audits, makes the certification decision and issues the certificate.
How long is an ISO 29001 certificate valid?
Three years. The certification body carries out surveillance audits in the first and second years, and a recertification audit before the three-year cycle ends.
Can ISO 29001 be combined with other standards?
Yes. ISO 29001 builds on ISO 9001 and shares the harmonised structure of ISO management system standards, so it can run as one integrated management system with, for example, ISO 14001 and ISO 45001, and certification bodies can often audit them together.
Which edition of ISO 29001 is current, and is there a transition?
The current edition is ISO 29001:2020, with the climate change amendment added in 2024. There is no transition under way.
