GB/T 13277.8-2023 Compressed air—Part 8:Test methods for solid particle content by mass concentration
Basic Information
Scope
This document describes the test method for measuring the mass concentration of solid particles in compressed air and the applicable particle size range, and specifies the sampling techniques, measurement methods, evaluation of test results, uncertainty, and requirements for test reports in this method.
This document is applicable to the measurement of the mass concentration of solid particles in compressed air.
Note 1: The method described in this document is applicable to particle concentrations of grades 6 to 7 as defined in GB/T 13277.1.
Note 2: The measurement method described in GB/T 13277.4 is applicable to particle concentrations of grades 0 to 5 as defined in GB/T 13277.1.
Note 3: The mass concentration of solid particles is expressed in terms of the mass of solid particles within the maximum particle size range.
