出版：Belgian Standards
专家解读视频
Defines performance requirements for pumps used within the scope of measuring methods for the determination of the concentration of chemical agents in the workplace environment. For pumps with nominal volumetric flow rates within the range from 51 to 400 litres/min. Applies to electrically driven pumps and air movers which induce air flow with the aid of another mechanism. Covers pumps built into sampling apparatus, pumps which are attached to a person, stationary or connected to a sampler by means of tubing during sampling.
