标准摘要
[中文适用范围]： 本文件规定了一种使用消光技术（也称为光阻挡或光遮蔽）在线或离线测定容器中颗粒污染水平的方法。 它还定义了校准仪器并验证其在实验室和使用中正确运行的程序。 一般而言，本文件中描述的技术适用于监测： ——液压系统的总体清洁度水平， — 冲洗操作的进度，以及 — 支持设备和试验台。 该方法的使用仅适用于单相液体系统。 [外文原描述]： This document specifies a method for the determination of the particulate contamination level using the light extinction technique (also known as light blockage or light obscuration) either online or offline in containers. It also defines procedures for calibrating the instruments and verifying their correct operation both in the laboratory and in service. In general, the techniques described in this document are suitable for monitoring: — the general cleanliness level in hydraulic systems, — the progress in flushing operations, and — support equipment and test rigs. The use of this method is applicable to single-phase liquid systems only.
