Workplace air — Chemical agent present as a mixture of airborne particles and vapour — Requirements for evaluation of measuring procedures using samplers
The procedures given in this document provide results only for the sum of airborne particles and vapour. The concentration is calculated in terms of mass per unit volume.
NOTE The physical behaviour of a mixture of airborne particles and vapour is described in Annex A. Examples of substances which can be present in multiple phases are toluene diisocyanate, diethanolamine, ethyleneglycol and tributylphosphate.
This document can also be applied to complex mixtures, such as metal working fluids or bitumen fumes.
This document is applicable to samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages.
