DEF / AUS32 Quality & ISO 22241
Purity, contamination control, batch traceability and buyer verification.
Thermal Fluids
DEF quality is defined by what the SCR system receives: correct urea concentration, high-purity water, very low contamination and compatible storage / transfer materials.
Quick AnswerINNOCHILL organizes DEF / AUS32 quality control around ISO 22241-focused product specification, clean production and filling, batch traceability and documentation that industrial buyers can use during receiving inspection.
Four quality controls that matter
32.5% AUS32 concentrationConcentration consistency is central to correct SCR dosing and NOx-reduction performance.
High-purity inputsHigh-purity urea and water reduce the risk of ionic, metallic and particulate contamination.
Clean filling systemProduction, transfer and packaging cleanliness help protect the dosing pump, injector and catalyst.
Batch traceabilityCOA and lot records support distributor quality systems and customer receiving inspection.
What procurement teams can verify
| Control point | Buyer value |
|---|---|
| Product specification | Clear acceptance criteria for concentration and impurity control. |
| COA / lot traceability | A documented link between delivered product and production batch. |
| Packaging compatibility | Reduces risk of contamination from unsuitable metals or transfer equipment. |
| Storage guidance | Helps preserve product quality during warehousing and distribution. |
Quality is a supply-chain issue, not only a laboratory result.
A technically compliant batch can still be compromised by dirty transfer equipment, incompatible containers or poor storage. INNOCHILL therefore treats packaging and handling as part of the DEF quality system.
