INTRODUCTION
Thepurposeofthispracticeistodescribebestpracticemethodsfortheanalysisoffilterdebrisfrom
machinery lubrication or hydraulic systems primarily for the purpose of machinery condition
monitoring. The purpose of Filter Debris Analysis (FDA) is to determine the health of oil-wetted
machinery by analyzing the size, quantity, morphology, and composition of debris trapped by the
system filter. FDA is emerging as an important condition monitoring technique as fine filtration
becomes more common and the associated reduction of metallic particulates makes traditional
elemental analysis of the lubricant less effective. System filters have an added advantage over
traditional sample-based techniques in that they capture a high percentage of the total system debris
(metallic, non-metallic, and organic particulate contamination) within the size range useful for
machinery condition monitoring.

Standard Practice for Processing In-service Fluid Samples for Particulate Contamination Analysis Using Membrane Filters

SIGNIFICANCE AND USE
4.1 This practice provides for the processing of liquid samples. It will provide the optimum sample processing for visual contamination methods such as Test Methods F312.
SCOPE
1.1 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.  
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 µm 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.  
1.5 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.

ASTM D7919-14(2021)(Guide)
Standard Guide for Filter Debris Analysis (FDA) Using Manual or Automated Processes

SIGNIFICANCE AND USE
5.1 This guide is intended to provide machinery maintenance and monitoring personnel with a guideline for performing filter debris analysis as a means to determine machine condition. Correlating the filter contaminants to ‘normal’ and ‘abnormal’ lube system operation provides early indication of a contaminant or component wear related lube system problem. Analysis of the contaminant collected within the lube filter element provides a tool to identify the failure mode, its rate of progression, and the source of the contamination.  
5.2 FDA differs from traditional oil analysis in that the filter is sampled instead of the fluid. Debris from the filter is removed for analysis. FDA is an effective means of monitoring equipment wear because the wear history is efficiently captured in the filter matrix. Typically, more than 95 % of all released metal particles larger than the filter pore size are captured in the filter (1).5 In addition, other types of particulate contamination, including seal wear material and environmental contaminations are captured, which can also provide diagnostic information.
SCOPE
1.1 This guide pertains to removal and analysis techniques to extract debris captured by in-service lubricant and hydraulic filters and to analyze the debris removed.  
1.2 This guide suggests techniques to remove, collect and analyze debris from filters in support of machinery health condition monitoring.  
1.3 Debris removal techniques range from manual to automated.  
1.4 Analysis techniques vary from visual, particle counting, microscopic, x-ray fluorescence (XRF), atomic emission spectroscopy (AES), and scanning electron microscopy energy dispersive x-rays (SEMEDX).  
1.5 This guide is suitable for use with the following filter types: screw on, metal mesh, and removable diagnostic layer filters.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 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.

ASTM D3861-22(Test Method)
Standard Test Method for Quantity of Water-Extractable Matter in Membrane Filters

SIGNIFICANCE AND USE
5.1 The presence of water-soluble extractables in membrane filters can create errors in test procedures employing membrane filters. However, these errors can be eliminated or significantly reduced if the quantity of water-soluble extractables of the specific membrane is previously determined. Certain membrane filter uses require specifications of maximum water-soluble extractable levels. This test method is intended to be a rapid test to determine the loss of water-soluble compounds such as plasticizers or wetting agents from filtration membranes. This test method is not designed to predetermine the performance of a filter, but is significant in determining the percent extractables of membranes from different sources and lot variations from a single source.
SCOPE
1.1 This test method covers the gravimetric determination of the water-extractable material present in membrane filters and is applicable over the complete concentration range of extractables.  
1.2 The analyst should be aware that collaborative data for a bias statement as required by Practice D2777 is not provided. See Section 11 for details.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

Standard Test Method for Determining Filtering Efficiency and Flow Rate of the Filtration Component of a Sediment Retention Device

SIGNIFICANCE AND USE
5.1 This test method is used to determine the filtering efficiency and flow rate of the filtration component of a sediment retention device, such as a silt fence, a silt barrier, or a silt curtain, for specific soil tested.  
5.2 This test method may be used for the design of the filtration component of a sediment retention device to meet requirements of regulatory agencies in filtering efficiency or flow rate for the specific soil tested.  
5.2.1 The designer can use this test method to determine the spacing between sediment retention devices.  
5.3 This test method is intended for performance evaluation, as the results will depend on the specific soil evaluated. Unless testing with the default soil is desired, it is recommended that the user or representative perform the test to pre-approve products, as sediment retention device manufacturers are not typically equipped to handle or test soil requirements.  
5.4 This test method provides a means of evaluating the filtration component of sediment retention devices with different soils under various conditions that simulate the conditions that exist in a sediment retention device installation. This test method may be used to simulate several storm events on the same sediment retention device specimen. Therefore, the number of times this test is repeated per specimen is dependent upon the user and the site conditions.
SCOPE
1.1 This test method is used to determine the filtering efficiency and the flow rate of the filtration component of a sediment retention device, such as a silt fence, silt barrier, or inlet protector.  
1.1.1 The results are shown as a percentage for filtering efficiency and cubic metres per square metre per minute (m3/m2/min) or gallons per square foot per minute (gal/ft2/min) for flow rate.  
1.1.2 The filtering efficiency indicates the percent of sediment removed from sediment-laden water.  
1.1.3 The flow rate is the average rate of passage of the sediment-laden water through the filtration component of a sediment retention device.  
1.2 This test method requires several specialized pieces of equipment, such as an integrated water sampler and an analytical balance, or a vacuum filtration system. At the client’s discretion, the test soil is either a site-specific soil or a soil that is representative of a target default gradation.  
1.3 The values stated in SI units are the standard, while the inch-pound units are provided for information. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.
