英文名称：Workplace air — Metals and metalloids in airborne particles — Requirements for evaluation of measuring procedures
发布日期：2018-11
标准范围
This document specifies performance requirements and test methods for the evaluation of procedures
for measuring metals and metalloids in airborne particles sampled onto a suitable collection substrate.
This document specifies a method for estimating the uncertainties associated with random and
systematic errors and combining them to calculate the expanded uncertainty of the measuring
procedure as a whole, as prescribed in ISO 20581.
This document is applicable to measuring procedures in which sampling and analysis is carried out in
separate stages, but it does not specify performance requirements for collection, transport and storage
of samples, since these are addressed in EN 13205-1 and ISO 15767.
This document does not apply to procedures for measuring metals or metalloids present as inorganic
gases or vapours (e.g. mercury, arsenic) or to procedures for measuring metals and metalloids in
compounds that could be present as a particle/vapour mixture (e.g. arsenic trioxide).
