标准范围

本文件规定了一种参考方法，使用透射电子显微镜测定各种环境空气情况下（包括建筑物的室内大气）空气中的石棉纤维和结构，并详细评估任何大气中的石棉结构。该方法允许确定存在的石棉纤维的类型，还包括测量石棉结构的长度、宽度和纵横比。该方法无法区分石棉的单个纤维和同一角闪石矿物的非石棉类似物的细长碎片（解理碎片和针状颗粒）[13]。

This document specifies a reference method using transmission electron microscopy for the determination of airborne asbestos fibres and structures in in a wide range of ambient air situations, including the interior atmospheres of buildings, and for a detailed evaluation for asbestos structures in any atmosphere. The method allows determination of the type(s) of asbestos fibres present and also includes measurement of the lengths, widths and aspect ratios of the asbestos structures. The method cannot discriminate between individual fibres of asbestos and elongate fragments (cleavage fragments and acicular particles) from non-asbestos analogues of the same amphibole mineral^[13].
