Overview
EN ISO 16961:2024/prA1 is a draft amendment to the international standard ISO 16961:2024, focused on the oil and gas industries, including the growing sector of lower carbon energy. This amendment addresses internal coatings and linings of steel storage tanks, providing specifications for pre-qualification testing using standard liquid and gas compositions. The document is developed by CEN in collaboration with ISO/TC 67 and CEN/TC 12, ensuring harmonization across Europe and globally. EN ISO 16961:2024/prA1 is vital for ensuring the durability and safety of storage tanks used for petroleum, natural gas, and other energy carriers.
Key Topics
- Pre-qualification of Internal Coatings: The amendment adds new informative annexes specifying standard liquid and gas compositions for the pre-qualification testing of coatings and linings.
- Updated Normative References: ISO 15184:2020 replaces previous references, ensuring alignment with current coating hardness test methods.
- Scope of Media Testing: Guidance is provided for testing against a variety of liquids and gases stored within steel tanks, such as crude oil, seawater, glycol, aviation fuel, and gasoline.
- Material Compatibility: Outlines which reagent grades and substances can be used to assess immersion performance.
- User Flexibility: Manufacturers can choose relevant compositions for pre-qualification or expand to additional compositions based on operational needs.
Applications
EN ISO 16961:2024/prA1 is highly relevant for organizations involved in the design, fabrication, coating, and maintenance of steel storage tanks in the oil and gas sector, with an increasing emphasis on lower carbon energy applications. Practical applications include:
- Quality Assurance in Tank Construction: Ensuring coatings are tested for performance with specific energy products, minimizing risk of corrosion and material degradation.
- Purchaser Specification: Providing clarity and consistency in specifying internal protective coatings that meet international industry requirements.
- Regulatory Compliance: Serving as a harmonized reference for the oil, gas, and energy industries to meet regional and international safety, quality, and environmental standards.
- Life Cycle Optimization: Helping asset owners extend the service life of steel tanks by verifying the suitability of protective systems for real-world liquid and gas exposures.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
