Standard Practice for Processing Aerospace Liquid Samples for Particulate Contamination Analysis Using Membrane Filters
N F311
Annotation
This practice covers the processing of liquids in preparation for particulate contamination analysis using membrane filters and is limited only by the liquid-to-membrane filter compatibility.
The practice covers the procedure for filtering a measured volume of liquid through a membrane filter. When this practice is used, the particulate matter will be randomly distributed on the filter surface for subsequent contamination analysis methods.
The practice describes procedures to allow handling particles in the size range between 2 and 1000 m with minimum losses during handling.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Автоматический перевод:
Общепринятая практика для обработки космических жидких образцов для анализа загрязнения макрочастицы Используя мембранные фильтры
Эта практика покрывает обработку жидкостей при подготовке к анализу загрязнения макрочастицы с помощью мембранных фильтров и ограничивается только совместимостью фильтра жидкости к мембране.
