ISO 22241

ISO 22241:2019 is an internationally recognized standard that specifies the quality requirements, handling, transportation, storage, and refilling guidelines for Diesel Exhaust Fluid (DEF), commonly known by the trademark AdBlue®. This standard ensures compatibility between selective catalytic reduction (SCR) systems in diesel vehicles and the urea solution used to reduce nitrogen oxide (NOx) emissions. The latest version of this standard, ISO 22241-1:2019, reflects updates aligning with current environmental compliance requirements and diesel vehicle emission technologies.

As a trusted ISO certification body, Quality Asia Certification offers ISO 22241:2019 certification services to help businesses in the automotive and chemical sectors demonstrate compliance with quality, safety, and environmental protection standards related to DEF.

What is ISO 22241?

ISO 22241:2019 Certification verifies that a company produces, distributes, or handles Diesel Exhaust Fluid in accordance with global quality parameters. The standard covers multiple parts:

  1. ISO 22241-1: Quality requirements
  2. ISO 22241-2: Test methods
  3. ISO 22241-3: Handling, transportation, and storage
  4. ISO 22241-4: Refilling interface
  5. ISO 22241-5: Refilling adapter

Organizations certified under this standard ensure their DEF products are safe, non-contaminated, and effective in controlling harmful emissions, thereby supporting regulatory compliance and cleaner transport.

Why is ISO 22241 important?

The demand for eco-friendly transportation solutions is growing rapidly, and SCR technology is now standard in most diesel engines. DEF plays a critical role in reducing NOx emissions, but its effectiveness heavily depends on the purity and quality of the urea solution.

By opting for ISO 22241:2019 certification, businesses:

  1. Meet global emission regulations
  2. Gain competitive advantage in international markets
  3. Ensure compatibility and longevity of vehicle SCR systems
  4. Build trust with vehicle manufacturers, suppliers, and end-users

This certification acts as a quality assurance mark in a highly regulated industry.

What are the benefits of ISO 22241?

  1. Ensures High-Quality DEF: Guarantees that urea solution meets the required chemical composition and purity standards.
  2. Prevents SCR Damage: Contaminated or incorrect DEF can corrode or malfunction SCR systems—this standard prevents that risk.
  3. Reduces Regulatory Risks: Demonstrates compliance with local and international vehicle emission laws.
  4. Supports Eco-Friendly Goals: Aligns your company with environmental sustainability initiatives.
  5. Covers Full Supply Chain: From manufacturing to dispensing, every aspect is standardized and controlled.

What kind of businesses can benefit from ISO 22241?

Implementing and certifying to ISO 22241:2019 brings tangible advantages to your organization:

  1. ✅ Improved Product Credibility: Gain trust from OEMs, logistics companies, and vehicle fleet owners.
  2. ✅ Market Expansion: Open up to international automotive and transport sectors where ISO 22241 compliance is required.
  3. ✅ Enhanced Customer Confidence: Show clients your DEF meets global safety and performance benchmarks.
  4. ✅ Minimized Legal Exposure: Reduce risks associated with non-compliance or substandard product use.
  5. ✅ Operational Efficiency: Standardized procedures across manufacturing, testing, and distribution improve internal consistency.
