标准摘要
[中文适用范围]： ISO 21018 的这一部分规定了一种使用过滤器堵塞技术（也称为网格遮蔽法或孔隙堵塞技术）在容器中在线或离线半定量测定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。 一般来说，ISO 21018 本部分描述的技术适用于监测 a) 液压系统的一般清洁度水平，b) 冲洗操作的进度，c) 支持设备和测试装置。 该方法的使用适用于所有单相或多相液体系统。 [外文原描述]： ISO 21018-3:2008 specifies a method for the semi-quantitative determination of the particulate contamination level using the filter blockage technique (also known as the mesh-obscuration method or the pore-blockage technique) either on-line or off-line in containers. ISO 21018-3:2008 also defines procedures for calibrating the instruments and verifying their correct operation both in the laboratory and in service. In general, the techniques 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 ISO 21018-3:2008 is applicable to all single- or multi-phase liquid systems.
