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 D8072-17(Classification)
Standard Classification for Reporting Solids and Insoluble Water Contamination of Hydrocarbon-Based Petroleum Products When Analyzed by Imaging Instrumentation

SIGNIFICANCE AND USE
4.1 The purpose of this code is to simplify the reporting of solid particle counts and water droplet concentrations present in petroleum products when measured by imaging instruments. Industry is accustomed to using a three number code to report contamination levels and so this reporting method for imaging instruments is presented to organize results in a similar format.  
4.2 Particle count results as described by this classification are reported per the preferred number ranges in Table 1. Preferred numbers were originally developed by Charles Renard and codified in ISO 3. This format is the preferred reporting format since ISO 4406 has no ability to report water.  
4.3 Imaging instruments are capable of identifying insoluble water droplets separate from solids, and therefore a suffix code is added after the three (or four) solid particle codes to report water content in parts per million (ppm (v)). To report water content, detected droplets will be converted to ppm (v). The distribution of water droplet size may be reported if it is useful, but it is not required.
SCOPE
1.1 This classification identifies a concise code which can be used by imaging instruments for reporting of solid particles and insoluble water content in hydrocarbon-based petroleum products. The coding system includes the reporting of water content and particle counts in the ≥1 µm range.
Note 1: Calibration is not in accordance with ISO 11171. Comparability to ISO 4406 and its requirements is not inferred.  
1.2 It is valid for imaging instruments measuring particle size by projected equivalent particle diameter (see 3.1.1), and which are calibrated and verified using particle size and count standards traceable to NIST.2  
1.3 Due to the variation of method and instrument types and resolutions, the reporting of results will include the ASTM standard used to conduct the analysis.  
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 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 and health practices and determine the applicability of regulatory limitations prior to use.  
1.6 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.

Standard Classification System for Nonmetallic Gasket Materials

SIGNIFICANCE AND USE
3.1 This classification system is intended to encourage uniformity in reporting properties; to provide a common language for communications between suppliers and consumers; to guide engineers and designers in the test methods commonly used for commercially available materials; and to be versatile enough to cover new materials and test methods as they are introduced.  
3.2 This system is based on the principle that nonmetallic gasket materials can be described in terms of specific physical and mechanical properties. This enables the user, or producer, to characterize a nonmetallic gasket based on properties that are important for the application.
SCOPE
1.1 This classification system2 provides a means for specifying or describing pertinent properties of commercial nonmetallic gasket materials. Materials composed of asbestos, cork, cellulose, and other organic or inorganic materials in combination with various binders or impregnants are included. Materials normally classified as rubber compounds are not included, since they are covered in Classification D2000. Gasket coatings are not covered, since details thereof are intended to be given on engineering drawings or in separate specifications. Facing materials for laminate composite gasket materials (LCGM) are included in Classification System F104. Assembled LCGMs are covered in Classification F868.  
1.2 Since all of the properties that contribute to gasket performance are not included, use of the classification system as a basis for selecting materials is limited.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.
