significance And Use:
This practice provides for the processing of liquid samples obtained in accordance with Practice F 302 and Practices F 303. It will provide the optimum sample processing for visual contamination... View More
scope:
1.1 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.
1.2 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.
1.3 The practice describes procedures to allow handling particles in the size range between 2 and 50 m with minimum losses during handling.
