Ships and marine technology. Marine NOx reduction agent AUS 40 - Quality requirements Ingestion-build-53008 2 Basic requirements for composition1 Scope This part of ISO 18611 specifies the quality characteristics of the marine NOx reduction agent, aqueous urea solution at 40 % concentration (AUS 40), which is needed to operate so called SCR (selective catalytic reduction) converters. In marine applications, for example, for engine exhaust gas treatment, SCR converters are particularly suitable for selectively reducing the nitrogen oxide (NOx) emissions of internal combustion engines and
