ISO 8573-1:2010 Compressed Air Specifications Trace Analytics, LLC specializes in the analysis of thousands of compressed air & gas samples each year. Many of our customers have established their own criteria by monitoring the performance of the system over a given time period, reviewing literature/specifications, evaluating equipment.
ISO 8573-1:2010 specifies purity classes of compressed air with respect to particles, water and oil independent of the location in the compressed air system at which the air is specified or measured. ISO 8573-1:2010 provides general information about contaminants in compressed-air systems as well as links to the other parts of ISO 8573, either for the measurement of compressed air purity or the specification of compressed-air purity requirements. In addition to the above-mentioned contaminants of particles, water and oil, ISO 8573-1:2010 also identifies gaseous and microbiological contaminants. Guidance is given in Annex A on the application of ISO 8573-1:2010.
Where do the contaminants come from?. Oils are used as lubricants in the compressors. Water is present naturally in the air in the form of relative Humidity. Small particles usually measured in Microns are present naturally in air. Corrosion particles flake off due to high flow rate. What can these contaminants do?.
Health of Machinery & Piping:. One cubic meter of untreated compressed air contains almost 200 million dirt particles and a lot of water, oil, lead, cadmium and mercury.
These contaminants can:. Corrode your piping system which in turn causes pressure losses. Cause constrictions and blockages. Reduce the life of filters and drains.

Reduce the service life of your machines. Reduce the functionality of your machines. Cost additional energy. Health of Product:. Moisture can provide the suitable environment for microbial growth. Corrosion Particles when flake off, can be transported along with air to the final product, where they can be a health hazard for the consumer.
Dirt particles contain pipe scale which can accumulate in your final product. Oil contains hydrocarbons, that can be hazardous for health. The ISO 8573-1 Standard ISO 8573-1:2010 is an international standard that:. Categorizes air quality into different classes. Specifies maximum permissible Contamination levels for each class.
Each class refers to certain Industrial applications. Air Quality for Food & Pharma Industry. Food & Drug manufacturing facilities require higher quality of air.
Since these products are to be ingested by Humans or Animals. Therefore air must be Completely oil free and must contain very few parts of water vapor. So air quality of class 1 or 2 is essential for food & pharma Industries.
