Leak testing in automotive air conditioning systems based on determination of the amount of refrigerant released. The test method consists of conditioning the test object in a sealed temperature chamber (MINI SHED) and analysing the concentration of refrigerant inside the MINI SHED using gas chromatography with flame ionisation detection (GC-FID).
- MINI SHED chamber
- internal dimensions: 600x600x1000 mm
