Compressed air - Part 1: Contaminants and purity classes
1 Scope
This part of GB/T 13277 specifies purity classes of compressed air in respect of particles, water and trace oil.
This part also identifies microbiological and gaseous contaminants.
The gaseous contaminants included in this part are carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen dioxide, nitric oxide and hydrocarbons with carbon atoms in the range C1 to C5.
Note: Other contaminants are taken into consideration for specific applications, e.g. air used for breathing, medical, food and beverage purposes.
