GB/T 13277.1-2023 Compressed air - Part 1: Contaminants and purity classes 1 Scope This document specifies the purity classes of compressed air with respect to particles, water and oil and the description method of viable microorganisms and gaseous pollutants. This document is applicable to the purity classification and description of pollutants in compressed air. Note: The purity classes of contaminants specified in this document is independent of the location in the compressed air system at which the air is specified or measured. This document provides general information about contaminants in compressed air systems as well as links to the other parts of GB/T 13277, either for the requirements of compressed air purity classes or its measurement methods. Guidance is given in Annex A as to the application of this document. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
