This European Standard specifies general performance requirements for procedures for the determination of the concentration of chemical agents in workplace atmospheres as required by the Chemical Agents Directive 98/24/EC (see reference [6]). These requirements apply to all measuring procedures, irrespective of the physical form of the chemical agent (gas, vapour, airborne particles), the sampling method and the analytical method used.
This European Standard is applicable to
all steps of a measuring procedure,
measuring procedures with separate sampling and analysis steps, and
direct-reading devices.
