COMPRESSED AIR FOR GENERAL USE—PART 1: CONTAMINANTS AND QUALITY CLASSES

1993-06-01
HISTORICAL
J1649/1_199306
This part of SAE J1649/1 specifies quality classes of industrial compressed air for general use (e.g., for workshops, the construction industry, pneumatic transport, etc.) without consideration of the quality of the air when it is discharged from the compressor. The quality class of compressed air for a particular application has to be based on the mean value of several measurements carried out over a specific period of time and under defined operating conditions. This part of SAE J1649/1 is not applicable to compressed air for direct breathing and for medical use.
