标准范围

本文件规定了测量方法和策略，用于确定每单位体积室内空气中的空气传播颗粒总数，使用冷凝颗粒计数器（CPC）测量大约10？纳米到3？μ m。笔记？由于颗粒数浓度通常由超细颗粒(UFP)分数主导，因此获得的结果可以用作UFP浓度的近似值。本文件还讨论了质量保证、测量不确定度的确定和最小报告信息。本文件适用于ISO 16000-1中规定的室内环境。本文件不涉及生物气溶胶的测定或颗粒的化学表征。然而，一些生物气溶胶可以被CPC检测到，然后有助于测量的颗粒计数。

This document specifies the measurement methods and strategies for determining the total number of airborne particles per unit volume of air indoor, using a condensation particle counter (CPC) for particles approximately between 10 nm to 3 μm.

NOTE      As the particle number concentration is usually dominated by the ultrafine particle (UFP) fraction, the obtained result can be used as an approximation of the UFP concentration.

Quality assurance, determination of the measurement uncertainty and minimal reporting information are also discussed in this document.

This document is applicable to indoor environments as specified in ISO 16000-1.

This document does not address the determination of bioaerosols or the chemical characterization of particles. Nevertheless, some bioaerosols can be detected by the CPC and then contribute to the measured count of particles.
