    ISO 9001 Diesel Exhaust Fluid (DEF) is a high-purity 32.5% urea solution used in SCR systems to reduce NOx emissions, complying with strict manufacturing quality standards (ISO 22241). It is non-toxic, non-flammable, and ensures optimal engine performance while meeting environmental regulations, often verified by API certification. 
    Key Aspects of ISO Certified DEF 
    • Composition: A mixture of 32.5% high-purity synthetic urea and 67.5% deionized water.
    • Standards: Must meet ISO 22241-1 specifications, which cover quality, handling, and storage to prevent SCR system damage.
    • Quality Assurance: ISO 9001 certification (often linked with ISO 22241) indicates strict manufacturing quality control.
    • API Certification: Many high-quality DEF brands are also API (American Petroleum Institute) certified.
    • Usage: Essential for modern diesel engines (post-2010/2014) to meet EPA emission standards.
