最新RP-CC014。2介绍了用于检测和测量空气和其他气体中单个颗粒大小的光学颗粒计数器（OPC）性能的校准和表征程序。这些程序旨在供OPC制造商、专业测试机构和维护校准和测试设施的OPC用户使用，以确定这些仪器的尺寸和计数精度。取代之前版本的IEST-RP-CC014。

IEST RP-CC014.2 covers procedures for calibrating and characterizing the performance of optical particle counters (OPCs) that detect and measure the size of single particles in air and other gases. These procedures are intended for use by OPC manufacturers, specialized test houses, and OPC users who maintain calibration and testing facilities to determine the sizing and counting accuracy of these instruments. Supersedes previous edition of IEST-RP-CC014.
