Specifies the performance requirements for pumps used within the scope of measuring methods for the determination of the concentration of chemical agents in the workplace atmosphere. The pumps and air movers are mainly used for aerosol sampling. This standard is valid for pumps with a nominal volumetric flow rate within the rangee 5 l/min to 400 l/min. This standard applies to electrically driven pumps and also to air movers, which induce air flow with the aid of another mechanisms, such as pressure drop at a critical nozzle. The standard applies to pumps which - are attached to a person and connected to the sampler by means of a tubing during sampling; - are stationary and which are connected to the sampler by means of a tubing during sampling; - are built-in into sampling apparatus which are either attached to a person or which are operated in a stationary position. Applies to pumps the nominal volumetric flow rate of which can be kept constant by an automatic controller if the flow resistance changes during sampling. The control range shall be specified by the manufacturer. This standard also applies to pumps which are operated at a constant pressure drop during sampling (e.g. pumps with rotating cups). For pumps which are built-are into sampling apparatus only those parts of this standard that deal with the air flow function apply. General requirements like mechanical and electrical safety etc. are to be specified in standards for the sampling apparatus.
