AdBlue Standards

(2007-09-03) The DIN 70070 and 70071 standards for AdBlue are being replaced by four new ISO standards:

ISO 22241-1 Quality requirements, specifies the quality characteristics of AdBlue needed to operate the SCR system on your vehicle. It is a final, published International Standard.

ISO 22241-2 Test methods, specifies test methods required for determination of the quality characteristics of AdBlue. It is also a published International Standard.

ISO/DIS 22241-3 Handling, transportation and storing, describes how to deal with AdBlue in practice and in its content is much like the CEFIC Quality Assurance Guidance Document. It is a ‘Draft Industrial Standard’ ready for final publication during March 2009.

ISO/DIS 22241-4 Refilling interface, describes elements pertaining to refilling components. It is also a draft and will be published next spring.

The first two standards can be purchased on the ISO websites:

ISO 22241-1 Quality requirements www.iso.org

ISO 22241-2 Test methods www.iso.org

It is strongly recommended to use only AdBlue that is produced and handled in accordance with these ISO standards. Using sub-specification urea solution can harm your SCR system and become a very costly mistake.

What does "ISO" stand for?

ISO (International Organization for Standardization) is the world's largest developer of standards. ISO's principle activity is the development of technical standards. 

ISO standards contribute to making the development, manufacturing and supply of products and services more efficient, safer and cleaner. They:

• make trade between countries easier and fairer.
• provide governments with a technical base for health, safety and environmental legislation.
• aid in transferring technology to developing countries.
• serve to safeguard consumers, and users in general, of products and services - as well as to make their lives simpler.

ISO is a network of the national standards institutes of 155 countries, on the basis of one member per country, with a Central Secretariat in Geneva, Switzerland, which coordinates the system.

What does "DIN" stand for?

DIN stands for "Deutsches Institut für Normung", which means "German Institute for Standardization". DIN Standards are the published results of DIN's work.

DIN, the German Institute for Standardization, develops norms and standards as a service to industry, the state and society as a whole. A registered non-profit association, DIN has been based in Berlin since 1917.

DIN's primary task is to work closely with its stakeholders to develop consensus-based standards that meet market requirements. Some 26,000 experts contribute their skills and experience to the standardization process.

By agreement with the German Federal Government, DIN is the acknowledged national standards body that represents German interests in European and International standards organizations. Ninety percent of the standards work now carried out by DIN is international in nature.

What is a standard?

A technical standard represents the state of technology as determined in a consensus-based process organized by a standards body. Standards lay down general and/or detailed specifications for products, procedures and services alike.

DIN EN 45020 defines the term "standard" as a "document, established by consensus and approved by a recognized body, that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context".
