Air purity and treatment

Which class do the measured values meet?

Assess particles, water and oil separately. A blank field means a missing measurement, not zero.

How we calculate

Method: Comparison of measured values with ISO 8573-1:2010 limits. For particle classes 1–5, the absence of particles >5 µm must be verified. For water classes 1–6, the absence of liquid water must be verified. Oil = aerosol + liquid + vapour. Class 0 is not assigned automatically.

Assumptions and limitations: Assessment of a partial sample, not a system certificate. Measurement uncertainty, sampling representativeness and the methods in the individual parts of ISO 8573 require professional assessment. Missing components are not treated as zero.
