ISO22241 Standards
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. It is much like the CEFIC QAGD above. Due for publication March 2009.
ISO/DIS 22241-4 Refilling interface, describes elements relating to refilling components. Also due to be published next year.
The first two standards can be purchased on the ISO website www.iso.org
ISO 22241-1 Quality requirements
ISO 22241-2 Test methods
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.
