Ships and marine technology. Marine NOx reduction agent AUS 40 - Quality requirements1 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

This part of IEC 62629 specifies the measuring methods of motion artifacts for stereoscopic displays using glasses

It does not apply to pairs of cylindrical gears connecting non-parallel axes known as crossed helical gears
