ISO 22241 Urea Solution (AdBlue) Quality Testing in Trade
The International Organization for Standardization has developed ISO 22241 to ensure the quality and purity of urea solutions used as diesel exhaust fluid, commonly known as AdBlue. This standard is crucial for ensuring that the urea solution meets the stringent requirements necessary for reducing nitrogen oxide emissions in diesel vehicles.
The testing process involves several critical steps aimed at guaranteeing compliance with ISO 22241 specifications. Specimens are meticulously prepared according to standardized protocols, and rigorous quality control measures are implemented throughout each step of the analysis. Our laboratory utilizes advanced instrumentation such as refractometers, viscometers, and conductivity meters to accurately assess key parameters like purity, density, viscosity, and total nitrogen content.
The importance of these tests cannot be overstated; they directly impact environmental compliance and fleet performance. Non-compliance can result in penalties for the manufacturer or distributor, as well as potential damage to the reputation of the brand involved. Compliance with ISO 22241 ensures that vehicles meet emissions standards set by regulatory bodies like the European Union's Environmental Protection Agency (EPA).
Our service not only guarantees compliance but also provides detailed reports highlighting any deviations from specified limits. This information is invaluable for quality assurance teams, R&D engineers, and procurement officers responsible for ensuring product integrity across supply chains.
Testing Parameters
The following parameters are typically analyzed:
- Total nitrogen content
- Purity levels (impurities)
- Density and specific gravity
- Viscosity
- Freezing point
- Bacterial contamination levels
These parameters are crucial for ensuring the efficiency of the urea solution in reducing NOx emissions. For instance, total nitrogen content must be precisely 32.5% ± 0.1%. Any deviation could lead to improper dosing and ineffective emission reduction.
Instrumentation
The laboratory uses state-of-the-art instrumentation including:
- Refractometers for measuring density and specific gravity
- Vinylidene chloride (VDC) viscometers to determine viscosity
- Infrared spectrophotometry for total nitrogen content analysis
- Bacterial culture methods for detecting contamination levels
Our highly skilled technicians ensure that each sample undergoes thorough examination, ensuring accurate and reliable results.
