Scope

This standard specifies the pumpless sampler sampling and solvent desorption gas chromatography method for the determination of the time-weighted average concentration (TWA) of benzene in the air at workplaces. This standard is applicable to the determination of the time-weighted average concentration of benzene in the air in workplaces.
