ISO 8573-4 Compressed Air - Contaminant Measurement - Particle Content

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ISO 8573-4 testing. This standard provides a method for sampling compressed air and a guide to selecting appropriate measuring equipment to determine particle size and concentration by number. It also explains the limitations of various measurement methods and explains considerations of evaluation and uncertainty.

This standard will report the particle size and concentration of all particle types combined and is not intended to separate solid and liquid particle fractions. When it is necessary to determine the concentration of a particular fraction, it is recommended to refer to the relevant standard method from the ISO 8573 series.

Particles are a common contaminant in compressed air and this document details correct sampling methodology and assists the user in selecting equipment and instrumentation and determining particle size and concentration.

Historically, the intention was to consider only solid particles for the purpose of particle purity class measurement. However, the detection methods detailed here are not substance selective and therefore this standard reports all particles present in compressed air within measured size ranges.
