ASTM D7670-10-Reapproved2021<\/h3>\n

Active Standard: Standard Practice for Processing In-service Fluid Samples for Particulate Contamination Analysis Using Membrane Filters<\/h4>\n
\n

ASTM D7670<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This 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.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> 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.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> The practice describes procedures to allow handling particles in the size range between 2\u2009\u00b5m and 1000\u2009\u03bcm with minimum losses during handling.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n<\/p><\/div>\n

\n

1.5<\/span> This 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.<\/i><\/p>\n<\/p><\/div>\n
