Scope
ISO 16232
Technical cleanliness of fluid system components
ISO 16232 specifies methods for assessing particle contamination in hydraulic, fuel, and coolant system components used in road vehicles. This standard defines procedures for extracting, counting, and classifying particles from functional parts like injectors, pumps, valves, and filters. The test is critical for automotive suppliers and OEMs to ensure component reliability and prevent system failures caused by particulate matter. ISO 17025 accreditation for this test guarantees metrological traceability and consistent contamination classification across European supply chains.
What it measures
- Particle size distribution (ISO 4406 code classification)
- Total particle count per component
- Contamination class of hydraulic fluid
- Fuel system particulate contamination
- Coolant circuit cleanliness level
