Significance and Use
4.1 This practice provides for the processing of liquid samples obtained in accordance with Practice F302 and Practices F303. It will provide the optimum sample processing for visual contamination methods such as Method F312, and Test Method F314.
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 1000 μm with minimum losses during handling.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
