ISO EN DIN 8573 compressed air quality

Home > ScienceISO EN DIN 8573 compressed air quality

The standard DIN ISO 8573-1 defines the quality classes of compressed air with regard to:

oil content

Determination of the residual amount of aerosols (liquid particles up to 0.01μ) and hydrocarbons (fully vaporized gaseous), which may be contained in the compressed air.

Particle size and density

Determination of size and concentration of the solid particles which may still be contained in the compressed air.

dew

Determination of the temperature to which the compressed air can be cooled without condensing the water vapor contained in it. The pressure dew point changes with the air pressure.

The standard is divided into two sections with nine subgroups with individual definitions. The standard is written as a worldwide standard in English and is available as a printed publication only in English:

Air quality in accordance with ISO8573-1: 2010

ISO8573-1 is the document of the ISO8573-1 document which specifies the amount of contravention allowed in each cubic meter of compressed air.

ISO8573-1 lists the main contaminants as Solid Particulate, Water and Oil.

 

 

Comment:

a filtration ratio β based on a particle size class is the ratio between the number of particles that flow in the filter and the number of particles that flow out in the filter. The ratio can be expressed by β = 1 / P. Here P is the penetration capacity of the particles, which is expressed by the ratio of the concentration of outflowing particles to the concentration of upflowing particles.

The particle size class is used as an index; the value β10 = 75 means, for example, that the number of particles with the size of 10 μm (β * m) and larger than 75 times higher flows than flows out.
