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