Application Summary AI generated
This standard specifies the test methods for verifying the quality and composition of AUS 40, a 40% urea solution used as a nitrogen oxide (NOx) reducing agent in marine selective catalytic reduction (SCR) systems. It is applied in shipbuilding and marine engineering contexts to ensure that the reducing agent meets the required purity, concentration, and performance criteria for compliance with IMO Tier III NOx emission regulations. The test methods cover parameters such as urea content, density, alkalinity, and impurities, enabling manufacturers, suppliers, and regulatory bodies to conduct consistent quality assessments.
