Air specifications - ISO 8573.1 standard

The standard provides a uniform way to specify air quality in terms of particle size, pressure dewpoint, and oil content.

Class 2-4-3 means class 2 particulate, class 4 dewpoint, and class 3 oil content. (1 micron particulate, 37 ￿F dewpoint, 1 mg/m3 oil content) (maximums)

The following table lists the maximum contaminations in each category.
