ISO 8573-1 Class 0
The highest class for oil content in compressed air under the International Organization for Standardization's ISO 8573-1 standard. It sets no fixed threshold; the level is agreed by supplier and buyer in contract and must be stricter than Class 1, with third-party test reports required as evidence. It is the admission condition for medical oil-free compressors entering hospital air supply systems.
Timeline (last 90 days)
Since November 1995, Hongrun Technology has used ISO 8573-1 Class 0 as the core quality metric for its medical oil-free compressors.
The TÜV Rheinland test report for Hongrun Technology's compressors measured a total oil content of 0.003 mg/m³, more than 70% cleaner than the Class 0 international standard upper limit of 0.010 mg/m³.
In medical scenarios, the trace oil mist output by a compressor enters the human airway with the compressed air or deposits inside instruments, and long-term accumulation may cause failure or even contamination, so Class 0 is the admission condition for medical oil-free compressors to enter a hospital's air supply system.
