The diesel engine finds application in transportation, logistics, agriculture, and industries because of its fuel economy and robustness. However, the diesel engine also results in NOx emissions that are detrimental to the environment. The Diesel Exhaust Fluid (DEF) or AUS 32, used for reducing NOx emissions through the Selective Catalytic Reduction technology, needs to conform to the quality norms specified by BIS IS 17042 (Part 1):2020, because it is the component that affects the emission control system performance.
As per Indian Standards, the composition of the AUS 32 requires adherence to several quality parameters including concentration of urea, quality of the raw material, alkalinity, biuret content, aldehyde, and contamination. It is important to follow the Quality Control Order and BIS certification of IS 17042 (Part 1):2020 in order to market and distribute the AUS 32 in India. The ISI mark on the Diesel Engine assures compliance with the environmental safety and performance standards of emission control systems.
AUS 32, popularly called AdBlue and Diesel Exhaust Fluid (DEF), is an aqueous solution containing 32.5% urea that is used in SCR systems in diesel engines to minimize NOx emissions and satisfy BS6 norms.
BIS certification is essential for AUS 32 products to ensure compliance with stringent quality and safety standards, as specified in the Diesel Engines – NOx Reduction Agent AUS 32 (Quality Control) Order, 2024. This certification, made mandatory by the Bureau of Indian Standards Act, 2016, prevents the sale of substandard products that could compromise engine performance or fail to meet NOx reduction targets. By certifying that AUS 32 meets IS 17042 (Part 1): 2018 standards, BIS certification assures consumers of its effectiveness in NOx emission reduction, supporting cleaner air and promoting sustainable practices in diesel engine operations.
Indian Standard IS 17042 (Part-1): 2018 specifies stringent quality and performance criteria for NOx Reduction Agent AUS 32, covering aspects like urea concentration, purity, and contamination levels to ensure its effectiveness in reducing nitrogen oxide emissions in diesel engines. This standard requires AUS 32 to meet precise chemical and physical properties, which are critical for safe and efficient NOx reduction. The 2024 Quality Control Order mandates BIS certification under this standard, reinforcing the use of AUS 32 as a dependable, high-quality emission control agent that aligns with environmental regulations and industry best practices.
The BIS certification process for Diesel Engines – NOx Reduction Agent AUS 32 involves multiple steps, designed to thoroughly evaluate a product's compliance with the required standards. Here is a general overview of the certification process:
Additional documentation may be required based on product specifications and environmental regulations.
BIS certification for Diesel Engines – NOx Reduction Agent AUS 32 is essential to ensure adherence to quality and safety standards as per IS 17042 (Part-1): 2018. By complying with the Electrical Accessories (Quality Control) Order, 2023, certified products provide reliable performance, enhance consumer safety, and reinforce the credibility of manufacturers in the Indian market.
