Abstract
Overview
ISO 22241-2:2019 - "Diesel engines - NOx reduction agent AUS 32 - Part 2: Test methods" defines the analytical and sampling procedures needed to verify the chemical quality of AUS 32 (aqueous urea solution) as required by . The standard specifies how to take representative samples, how to measure key chemical characteristics, and how to interpret results including precision and dispute procedures. It includes normative test methods (Annexes B–I) and informative guidance (Annex J) for identity checks, plus precision data (Annex K).
