  7. Objective and rationale, including the nature of urgent problems where 
applicable:  Diesel Engines — NOx Reduction Agent AUS 32, the NOx reduction agent 
AUS32 (aqueous urea solution) is used as NOx reduction agent, which is needed for 
selective catalytic reduction (SCR) in converter system of motor vehicle havin g diesel 
engines. SCR converter systems are suitable for selectively reducing the nitrogen oxide 
(NOx) emissions of diesel engines.  
The aqueous urea solution i.e. Diesel Engines — NOx Reduction Agent AUS 32 is 
technically pure urea and pure water, having a  urea content of 32,5 % (mass fraction), 
used as a NOx reduction agent in SCR converter system. Technically pure urea is an 
industrially produced grade of urea having CAS Number 57 -13-6, with traces of biuret, 
ammonia and water only, free of aldehydes or o ther substances such as anticaking agent, 
also free of contaminants such as sulphur and its compounds, chloride, nitrate or other 
compounds. Manufacturer produces AUS 32 finished product by dilution of virgin urea, 
dilution of concentrated urea solution or  dissolution of solid urea.  
The Order seeks to ensure that the locally manufactured or imported goods shall conform 
to the Indian Standard IS 17042 (Part -I) 2020/ISO 22241 -1:2019 and shall bear the 
standard mark under license from the Bureau of Indian Stan dards (BIS) as per Scheme -
