prEN ISO 23861

This document specifies performance requirements and test methods under prescribed laboratory conditions for the evaluation of pumped samplers used in conjunction with an air sampling pump and of procedures using these samplers for the determination of semi-volatile chemical agent in workplace atmospheres. 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. This document is applicable to pumped samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages.
