润滑油清洁度也叫颗粒污染度、NAS等级。是指通过检测油液中污染粒子的数量、大小分布来评价油液的被污染的程度。 二、监测的意义 润滑油在生产、运输、存储以及使用过程中,不可避免的会受到污染、老化降解。进行污染控制的目的是最大限度地保持油液的清洁,从而延长设备和润滑油的使用周期。 三、分析方法 测定方法...
valid inferences are to be drawn from observed data to characterise the level of particulate contamination in a large group of units. METHOD 1.LIGHT OBSCURATION PARTICLE COUNT TEST Use a suitable apparatus based on the principle of light blockage which allows an automatic determination of the size...

For example, particulate contamination is the major cause of yield loss in semiconductor manufacturing. In a controlled environment such as a cleanroom, the source of particles could be from personnel activities and different processing steps. The contaminants could impact the mask for lithography, ...
within an enclosed circuit. Solid particle contaminant is always present in the hydraulic fluid and the amount needs to be determined because particulate contamination can cause serious problems. Although filters are installed to keep particulates u...
EUROPEAN PHARMACOPOEIA 7.02.9.20. Particulate contamination: visible particlesdescribed below. If more than 20 particles 10 μm or largerin size or if more than 5 particles 25 μm or larger in size arepresent within the filtration area, the precautions taken for thetest are not sufficient. The...
Concern over the recent introduction of limits for allowable particulate contamination in small volume parenterals by the United States Pharmacopeia XXI has drawn attention to the physics of systems containing small numbers of particles of varying (random) size and random identity dispersed in an ...
Larger particles of ≥10 and 25 µm were also significantly reduced. Adding an extension set to the egress of the in-line filter (V = 1.7 mL) caused a significant increase in particulate contamination for both. This study showed that in-line filtration is an effective tool in ...
- **制药学:**在制药学中,"particulate contamination"(颗粒污染)是指在制药过程中引入的微小颗粒,可能对制成品的质量和安全性产生影响。 - **工程学:**在工程学中,"particulate flow"(颗粒流动)是研究颗粒在流体中的运动行为,对于设计输送系统和颗粒处理设备至关重要。 ### 5. **相关术语:** - **Partic...
