Measuring Compressed Air Quality according to ISO 8573
Compressed air is an expensive, but also indispensable medium in industrial, automated production. It is therefore all the more important for users to always keep an eye on the quality of their compressed air system.
ISO 8573 is an internationally recognised standard that defines the most important impurities in compressed air. The implementation of this standard supports the precise testing of the most important impurities in compressed air particles, water, gas, microbiological and oil contamination.
However, some of these methods require samples to be analyzed in a laboratory. This is always associated with time delays and only provides the customer with an average snapshot over the measured period and is not always practical.
So how do we measure these impurities under everyday, real operating conditions?
CS Instruments offers this customized solutions for stationary and mobile monitoring. An alarm can be used to signal that maintenance work is required on the compressed air treatment system (dryer and filter) so that oil, water and particles do not enter the compressed air network. This reduced prevents the risk of contamination of end products and increases the process reliability and lifespan of pneumatic components.
ISO 8573 consists of the following parts, under the general title Compressed air:
Usage for compressed air:
- Part 1: Contaminants and purity classes
- Part 2: Test methods for oil aerosol content
- Part 3: Test methods for measurement of humidity
- Part 4: Test methods for solid particle content
- Part 5: Test methods for oil vapour and organic solvent content
- Part 6: Test methods for gaseous contaminant content
- Part 7: Test method for viable microbiological contaminant content
- Part 8: Test methods for solid particle content by mass concentration
- Part 9: Test methods for liquid water content
