ISO 8573.1: 2010 AIR QUALITY CLASSES

ISO 8573.1: 2010 AIR QUALITY CLASSES

ISO 8573, the international standard for compressed air quality, defines the amount of contamination permissible in compressed air.

• The standard identifies three primary forms of contamination in compressed air systems − solid particles, water and oil.

• Contaminants are classified and assigned a quality class, ranging from Class 0, the highest purity level, to Class 9, the most relaxed
