规定方法的原理是从移动气流中等速提取已知体积，使取样气体通过过滤介质以去除颗粒物（包括纤维），处理过滤器使其在显微镜下观察时透明，并在使用相差光学显微镜观察的精确区域数中计算纤维数量。该方法可用于测定管道、烟囱或各种工业过程烟道中流动气流中的纤维浓度。

The principle of the method specified is isokinetically withdrawing a known volume from a moving gas stream, passing the sampled gas through a filter medium to remove particulate matter (including fibres), treating the filter to make it transparent when viewed under a microscope and counting the number of fibres in a precise number of fields viewed using a phase-contrast optical microscope. The method may be used to determine fibre concentrations in flowing gas streams in ducts, chimneys, or flues from a wide range of industrial processes.
