|Significance and Use|
4.1This practice provides for the processing of liquid samples. It will provide the optimum sample processing for visual contamination methods such as Test Methods .
1.1This practice covers the processing of in-service fluids in preparation for particulate contamination analysis using membrane filters and is limited only by the liquid-to-membrane filter compatibility.
1.2The 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.
1.3The practice describes procedures to allow handling particles in the size range between 2m and 1000?m with minimum losses during handling.
1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
