5.1 This guide covers procedures for quantifying the elemental composition of phases in a microstructure. It includes both methods that use standards as well as standardless methods, and it discusses the precision and accuracy that one can expect from the technique. The guide applies to EDS with a solid-state X-ray detector used on an SEM or EPMA.5.2 EDS is a suitable technique for routine quantitative analysis of elements that are 1) heavier than or equal to sodium in atomic weight, 2) present in tenths of a percent or greater by weight, and 3) occupying a few cubic micrometres, or more, of the specimen. Elements of lower atomic number than sodium can be analyzed with either ultra-thin-window or windowless spectrometers, generally with less precision than is possible for heavier elements. Trace elements, defined as <1.0 %,2 can be analyzed but with lower precision compared with analyses of elements present in greater concentration.1.1 This guide is intended to assist those using energy-dispersive spectroscopy (EDS) for quantitative analysis of materials with a scanning electron microscope (SEM) or electron probe microanalyzer (EPMA). It is not intended to substitute for a formal course of instruction, but rather to provide a guide to the capabilities and limitations of the technique and to its use. For a more detailed treatment of the subject, see Goldstein, et al. (1) This guide does not cover EDS with a transmission electron microscope (TEM).1.2 Units—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.

5.1 The plastic Petri plate (carrier) provides a closed system for enumeration and easy application of a pre-saturated or impregnated antimicrobial towelette by an analyst.5.2 Aliquoting of sterile 5 % non-heat-inactivated fetal bovine serum (five 10 µL spots) onto soiled carriers and inoculation of final test suspension onto treated carriers (five 10 µL spots) is conducted using a template and a positive displacement pipette, thereby ensuring a precise inoculum level and uniform distribution of soil and final test suspension.5.3 A single towelette is tested per 2-carrier set, eliminating the likelihood of cross contamination between carriers.5.4 The corkscrew-patterned circular motion of the product application (wipe outside to inside, wipe inside to outside using the wiping template; see Annex A3 – Annex A6) ensures uniform coverage and contact of disinfectant with the inoculated surface.5.5 The addition of neutralizer to the treated carriers at the end of the contact time results in neutralization of the test substance. This standard test method provides a procedure for performing neutralization verification to confirm that the microbicidal, microbistatic, or both types of activity of a test substance has been reduced by 50 % at the end of the contact time (see Annex A1 for neutralization verification procedure).5.6 The design of this standard test method minimizes any loss of viable organisms through carrier wash-off.5.7 It is optional to adjust (dilution in PBS) the inoculum to achieve desired control counts of 5.0 log10 CFU/carrier to 6.5 log10 CFU/carrier.5.8 Include, where applicable, comparisons of the test to other similar procedures such as Practices E1054 and E2362.1.1 This test method quantitatively determines the effectiveness of various sizes of antimicrobial towelettes in treating hard, non-porous surfaces against Pseudomonas aeruginosa and Staphylococcus aureus.1.2 This test method may be used to evaluate towelettes for antimicrobial efficacy against additional microorganisms (with necessary modifications).1.2.1 This test method does not differentiate between chemical inactivation of the test microbe and mechanical removal of inoculum from a surface; rather, product efficacy is considered a combination of both attributes of a towelette-based formulation.1.3 This test method involves the use of hazardous materials, chemicals, and infectious microorganisms and therefore should be performed only by those trained in microbiological techniques in facilities designed and equipped for work with infectious agents at the appropriate biosafety level, a BSL-2 or higher laboratory; specifications provided in the “Biosafety for Biomedical and Microbiological Laboratories” (BMBL), 6th edition (BMBL).1.4 It is the responsibility of the investigator to determine whether Good Laboratory Practices (GLP Standards—For example, 40 CFR, Part 160 of FIFRA) are required and to follow them when appropriate.1.5 Strict adherence to the protocol is necessary for the validity of the test results.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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.1.8 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.

4.1 All of these test methods can be used for quantitative determinations of asphalt binder in asphalt mixtures and pavement samples for specification acceptance, service evaluation, control, and research. Each method prescribes the solvent or solvents and any other reagents that can be used in the test method.NOTE 2: Further testing of the asphalt mixture may be performed by using sieve analysis on the extracted aggregate, Test Method D5444, or recovering the extracted asphalt binder from solution by Test Method D1856, Practice D5404/D5404M, or Practice D7906 for asphalt binder property testing. When recovering the asphalt binder for property testing, all mineral matter should be removed from the effluent.NOTE 3: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing/sampling/inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.1.1 These test methods cover the quantitative determination of asphalt binder content in asphalt mixtures and pavement samples. Aggregate obtained by these methods may be used for sieve analysis using Test Method D5444. This test is not appropriate for testing asphalt mixtures containing coal tar.1.2 Asphalt binder may be recovered using Test Method D1856, Practice D5404/D5404M, or Practice D7906.1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards are given in Section 7.NOTE 1: The results obtained by these test methods may be affected by the age of the material tested, with older samples tending to yield slightly lower asphalt binder content. Best quantitative results are obtained when the test is made on mixtures and pavements shortly after their preparation. It is difficult to remove all the asphalt when some aggregates are used and some chlorides may remain within the mineral matter affecting the measured asphalt content.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.
