ASTM E3294-23(Guide)
Standard Guide for Forensic Analysis of Geological Materials by Powder X-Ray Diffraction

SIGNIFICANCE AND USE
5.1 The overarching goals of the forensic analysis of geological materials include (A) identification of an unknown material (see 11.3), (B) analysis of soils, sediments, or rocks to restrict their possible geographic origins as part of a provenance analysis (see 11.4), and (C) comparison of two or more samples to assess if they could have originated from the same source or to exclude a common source based on observation of exclusionary differences (see 11.5). XRD is only one analytical method that can be applied to the evidentiary samples in service of these distinct goals. Guidance for the analysis of forensic geological materials can be found in Refs (2-4).  
5.2 Within the analytical scheme of geological materials, XRD analysis is used to: identify the crystalline components within a sample; identify the crystalline components separated from a mixture, typically clay-sized material (see 8.8), or a selected particle class for which additional analysis is needed (see 8.11); or compare two or more samples based on the identified crystalline phases or diffraction patterns (see 11.5).  
5.2.1 Non-destructive XRD analysis can be performed in situ on geological material adhering to a substrate (see 8.12.3).  
5.2.2 The most common forensic applications of XRD to geological materials are (A) identification or confirmation of a selected phase or fraction of a sample (see 8.12), (B) identification of minerals in the clay-sized fractions of soils (see 8.8), and (C) identification of the phases of the hydrated cement component of concrete or mortar.  
5.3 This guide is intended to be used with other methods of analysis (for example, polarized light microscopy, scanning electron microscopy, palynology) within a more comprehensive analytical scheme for the forensic analysis or comparison of geological materials.  
5.3.1 Comprehensive criteria for forensic comparisons of geological material integrating multiple analytical methods and provenance estimations (see 11.4) are ...
SCOPE
1.1 This guide covers techniques and procedures for the use of powder X-ray diffraction (XRD) in the forensic analysis of geological materials (to include soils, rocks, sediments, and materials derived from them such as concrete), to enable non-consumptive identification of solid crystalline materials present as single components or multi-component mixtures.  
1.2 This guide makes recommendations for the preparation of geological materials for powder XRD analysis with adaptations for samples of limited quantity, instrumental configuration to generate high-quality XRD data, identification of crystalline materials by comparison to published diffraction data, and forensic comparison of XRD patterns from two or more samples of geological materials to support criminal investigations.  
1.3 Units—The values stated in SI units are to be regarded as standard. Other units are avoided, in general, but there is a long-standing tradition of expressing X-ray wavelengths and lattice spacing in units of Ångströms (Å). One Ångström = 10–10 meter (m) = 0.1 nanometer (nm).  
1.4 This standard is intended for use by competent forensic science practitioners with the requisite formal education, discipline-specific training (see Practice E2917), and demonstrated proficiency to perform forensic casework.  
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, health, and environmental 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.

Standard Practice for Operating Characteristics of Home Reverse Osmosis Devices

SIGNIFICANCE AND USE
5.1 Home reverse osmosis devices are typically used to remove salts and other impurities from drinking water at the point of use. They are usually operated at tap water line pressure, with water containing up to several hundred milligrams per litre of total dissolved solids. This practice permits measurement of the performance of home reverse osmosis devices using a standard set of conditions and is intended for short-term testing (less than 24 h). This practice can be used to determine changes that may have occurred in the operating characteristics of home reverse osmosis devices during use, but it is not intended to be used for system design. This practice does not necessarily determine the device’s performance when solutes other than sodium chloride are present. Use Practice D4516 and Test Methods D4194 to standardize actual field data to a standard set of conditions.  
5.2 This practice is applicable for spiral-wound devices.
SCOPE
1.1 This practice covers determination of the operating characteristics of home reverse osmosis devices using standard test conditions. It does not necessarily determine the characteristics of the devices operating on natural waters.  
1.2 This practice is applicable for spiral-wound devices.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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 Practice for Calculation of Gas Chromatographic Response Factors

SIGNIFICANCE AND USE
5.1 ASTM standard gas chromatographic methods for the analysis of petroleum products require calibration of the gas chromatographic system by preparation and analysis of specified reference mixtures. Frequently, minimal information is given in these methods on the practice of calculating calibration or response factors. Test Methods D2268, D2427, D2804, D2998, D3329, D3362, D3465, D3545, and D3695 are examples. The present practice helps to fill this void by providing a detailed reference procedure for calculating response factors, as exemplified by analysis of a standard blend of C6 to C11 n-paraffins using n-C12 as the diluent.  
5.2 In practice, response factors are used to correct peak areas to a common base prior to final calculation of the sample composition. The response factors calculated in this practice are “multipliers” and prior to final calculation of the results the area obtained for each compound in the sample should be multiplied by the response factor determined for that compound.  
5.3 It has been determined that values for response factors will vary with individual installations. This may be caused by variations in instrument design, columns, and experimental techniques. It is necessary that chromatographs be individually calibrated to obtain the most accurate data.
SCOPE
1.1 This practice covers a procedure for calculating gas chromatographic response factors. It is applicable to chromatographic data obtained from a gaseous mixture or from any mixture of compounds that is normally liquid at room temperature and pressure or solids, or both, that will form a solution with liquids. It is not intended to be applied to those compounds that react in the chromatograph or are not quantitatively eluted. Normal C6 through C11  paraffins have been chosen as model compounds for demonstration purposes.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 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.  
1.4 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 Guide for Per- and Polyfluoroalkyl Substances Site Screening and Initial Characterization

SIGNIFICANCE AND USE
4.1 PFAS are widely used in commercial and industrial applications worldwide (see Fig. 1). PFAS are of concern due to their documented persistence and their studied impacts on human health and the environmental. While there is no comprehensive source of information on the many individual PFAS substances and their functions in different applications, a range of resources are available to the practitioner. This guide provides information to assist the practitioner in navigating these challenges during the initial screening and site characterization process.
FIG. 1 Activity/Industry that may be Sources of PFAS Use and Release
Source: AEI Consultants  
4.2 The user should note that PFAS regulatory management framework at the federal and state level are evolving quickly. Therefore, consultation with legal and technical representatives with knowledge of federal, state, and local PFAS regulations is advised prior to use of this guide. Environmental audit policies or privileges may be applicable to some of the steps described in this guide (see EPA, 2000).  
4.3 Multi-step Risk Management Framework:  
4.3.1 The actions described in this guide are intended to provide a multi-step risk management framework to confirm, with reasonable certainty, that PFAS may have been used at a federally-owned, publicly-owned, or privately-owned property. This standard provides guidance on how to focus limited resources on using a multi-step process, illustrated in Fig. 2, to identify property potentially impacted by on-site or off-site uses and releases of PFAS. Section 4.5 describes the use and occurrence of PFAS. Section 4.6 describes activities at government and federal installations where PFAS use is expected. Section 4.7 broadly outlines the industry sectors where the use of PFAS has been documented (Glüge, 2020 (2), Gaines, 2022 (3)).
FIG. 2 Initial Site Screening and Characterization Flow Diagram  
4.4 PFAs History and Use:  
4.4.1 In the 1940s, industrial processes to co...
SCOPE
1.1 Per- and polyfluoroalkyl substances (PFAS) are a group of over 7,000 manmade compounds consisting of polymeric chains of carbon bonded to fluorine atoms, usually with a polar functional group at the head. This guide recognizes that PFAS can be categorized as polymeric or nonpolymeric, collectively amounting to more than 4,700 Chemical Abstracts Service (CAS)-registered substances. Environmental concerns pertaining to PFAS are centered primarily on the perfluoroalkyl acids (PFAA), a subclass of per-and polyfluoroalkyl substances, which display extreme persistence and chain-length dependent bioaccumulation and adverse effects in biota.  
1.2 The regulatory framework for PFAS continues to evolve, both domestically and internationally. The United States Environmental Protection Agency (EPA) is proceeding with a wide-ranging set of PFAS regulatory actions (EPA, 2021). While the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) does not currently recognize PFAS as hazardous substances, the statute does require actions to protect public health and the environment from contaminants and pollutants released to the environment. Other federal regulatory programs, such as the Safe Drinking Water Act are being used to address drinking water supplies adversely impacted by releases of PFAS. The Clean Water Act’s National Pollutant Discharge Elimination System (NPDES) permitting program is tool that both federal and state regulators are using to regulate the inflows of PFAS-impacted wastewaters at both publicly-owned treatment works (POTW) and federally-owned wastewater treatment plants and the concentration of PFAS in permitted effluent. EPA continues to add additional per-and polyfluoroalkyl substances to the list of substances reportable under the federal Toxic Release Inventory (TRI) reporting program. International efforts to address per-and polyfluoroalkyl substances include Australia’s PFAS Nation...
