BIS Certification for AUS 32 Diesel NOx Reduction Agent IS 17042 Part 1:2020 - Visionary Horizons LLP, Karjan, Vadodara | Standphill India

Standphill India successfully completed BIS ISI Mark certification under IS 17042 Part 1:2020 for Visionary Horizons LLP - a manufacturer of AUS 32, the diesel engine NOx reduction agent, based at 226, Aatmiya Brookfieldz Industrial Park, Karjan Dabhoi Road, Karjan, Vadodara, Gujarat. The BIS license bearing number 710007**** was officially granted on September 11, 2024. Standphill India managed the complete certification from factory assessment at the Karjan facility to final license grant.

Visionary Horizons LLP is a manufacturer of AUS 32 - the aqueous urea solution used as a NOx reduction agent in diesel engines - based at Aatmiya Brookfieldz Industrial Park, Karjan, in Vadodara district of Gujarat. Karjan is an industrial town on the Karjan Dabhoi Road in Gujarat's industrially active Vadodara region, which hosts a significant concentration of chemical, automotive component, and specialty manufacturing operations.

AUS 32 - also widely known as AdBlue or Diesel Exhaust Fluid (DEF) - has become a critical product in India's automotive and commercial vehicle supply chain following the nationwide implementation of BS6 emission norms. Every diesel vehicle equipped with a Selective Catalytic Reduction (SCR) system requires a continuous supply of AUS 32 to reduce nitrogen oxide emissions and maintain BS6 compliance. With BIS ISI Mark certification under IS 17042 Part 1:2020 mandatory for AUS 32 manufacturers, Visionary Horizons LLP engaged Standphill India to manage the complete licensing process - and the license was granted on September 11, 2024.

IS 17042 Part 1:2020 is the Bureau of Indian Standards specification for AUS 32 - the aqueous urea solution containing 32.5% high-purity urea used as a NOx reduction agent in diesel engine Selective Catalytic Reduction systems. This standard defines the quality requirements that AUS 32 manufacturers must meet to ensure the product performs correctly in SCR systems without causing catalyst damage, sensor fouling, or system malfunction.

AUS 32 is a chemically sensitive product. Even small contamination by metals, minerals, or incorrect urea concentration can damage the SCR catalyst - which is an expensive component in commercial vehicles and passenger cars. IS 17042 Part 1:2020 sets very precise chemical quality requirements to prevent this.

Key requirements under IS 17042 Part 1:2020 include:

1. ) Urea concentration - AUS 32 must contain 32.5% urea by weight within a defined tolerance of ±0.7%

2. ) Refractive index - used as a rapid verification parameter for urea concentration

3. ) Density - must fall within the defined range corresponding to 32.5% urea concentration

4. ) pH value - the solution must be within the specified alkalinity range

5. ) Biuret content - biuret is a urea decomposition product that damages SCR catalysts and must be below defined limits

6. ) Aldehyde content - must be within specified limits to prevent catalyst poisoning

7. ) Heavy metals - extremely low limits for iron, copper, zinc, chromium, and other metals that could damage the SCR catalyst

8. ) Calcium and magnesium content - must be within specified low limits

9. ) Sodium and potassium content - controlled to prevent SCR system contamination

10. ) Phosphate content - must be below the specified limit

11. ) Marking and labelling requirements for certified AUS 32 product batches

BIS certification under IS 17042 Part 1:2020 is mandatory for AUS 32 manufacturers under the BIS Act, 2016. Vehicle manufacturers, fleet operators, petrol pump dispensing systems, and automotive aftermarket channels all require BIS-certified AUS 32 - and the product is increasingly subject to enforcement at point of sale and during commercial vehicle inspections.

If your manufacturing unit produces AUS 32 - diesel NOx reduction agent - and you need BIS ISI Mark certification under IS 17042 Part 1:2020, Standphill India can manage the complete process for you. We understand the chemical quality requirements of IS 17042, the testing parameters involved, and what BIS auditors look for in an AUS 32 manufacturing facility.

With BS6 compliance driving consistent demand for certified AUS 32 across India's commercial vehicle and passenger car fleets, having your BIS license in place is both a legal requirement and a direct commercial advantage.
