标准范围

This International Standard specifies methods for evaluation of sampler performance in terms of workplaceconditions: wind speed, humidity, temperature, atmospheric pressure, and analyte variation. The concise setof experiments specified aims to minimize cost to the user. The evaluation is limited to conditions commonlyencountered in personal sampling in the indoor workplace setting, namely wind speeds of up to 0,5 m/s andfor sampling periods typically from 2 h to 8 h.Static or area sampling, unlike personal sampling where movement of the subject is significant, maysometimes be subject to sampling-rate reduction due to stagnation at very low wind speeds. This InternationalStandard therefore does not apply to wind speeds of less than 0,1 m/s relative to static samplers. Samplersare also tested for compliance with the manufacturer's stated limits on capacity, possibly in the presence ofinterfering compounds. Given a suitable exposure chamber, the sampler evaluation protocol can be extendedto cover sampler use for other sampling periods and conditions.This International Standard indicates how to measure diffusive sampler uncertainty for characterizingconcentration estimates obtained subsequent to the evaluation. It is impractical continually to re-evaluatediffusive sampler performance under various environmental conditions prevailing during application.
