ASTM D2998-89(1996)e1 Standard Test Method for Polyhydric Alcohols in Alkyd Resins (Withdrawn 2004) Withdrawn, No replacement 发布日期 :  1970-01-01 实施日期 : 

1.1 This test method covers the qualitative and quantitative determination of the polyols in alkyl resins, including resin- and polymer-modified alkyds. Quantities as low as 0.5% may be detected and measured.1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.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 and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 7.

1.1 The purpose of this guide is to provide guidance in determining site-specific conversion factors for translating between dose limits and residual radioactive contamination levels on equipment, structures, and land areas. This guide does not endorse specific levels of allowable residual radioactive contamination, nor does it provide a methodology for population dose calculations. 1.2 Standards prescribing dose limits for decommissioned nuclear facilities or sites and/or private properties contaminated with radioactive materials are necessary to identify decommissioning methods, guide cleanup (remedial action) efforts, determine cleanup costs, identify the amount of radioactive waste to be disposed, and protect the public. Such standards, however, are not yet available for all types of nuclear facilities, sites, or properties. Regulatory Guide 1.86 of the U.S. Nuclear Regulatory Commission (NRC) (1), as well as specific promulgations of the Environmental Protection Agency (EPA) and the Department of Energy (DOE), provide some specific guidance. 1.3 This guide is not intended to establish these federal policies. They will be promulgated by the EPA and other federal agencies. Rather, it is to serve as a guide to acceptable methodology for translating the yet to be determined dose limits into allowable levels of residual radioactive materials that can be left at a site following decommissioning. 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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This practice covers fundamental forms of plots, used to convert measured intensities into concentrations in both photographic and direct reading analysis. It includes equations suitable for use with calculators or computers for such conversions, and methods for making background corrections and corrections for interferences from other elements. 1.2 A previous issue of this practice attempted to treat optical emission and X-ray fluorescence as one field, employing similar calculations to convert measured radiation intensities into concentrations. In fact, quite different procedures are used in the two fields. This practice confines itself to optical emission spectrochemical analysis. A separate practice will be devoted to calculations in X-ray fluorescence spectroscopy. 1.3 This practice is related to but should be distinguished from: 1.3.1 Practice E116, which describes procedures for converting either transmittance or optical density of lines on a photographic emulsion into intensities or relative intensities. This step is required in photographic analysis before the present practice can be applied. 1.3.2 Practice E305, which describes the procedures for fitting a curve to a group of plotted points, and for standardizing the equipment, in order to obtain optimum accuracy, guided by sound statistical practice. 1.3.3 Practice E876 discusses the statistical treatment commonly applied to spectrochemical data, such as calculating the standard deviation and the relative standard deviation. 1.4 This practice includes the following sections: Section Referenced Documents 2 Terminology 3 Significance and Use 4 Fundamental Theory 5 Plotting Analytical Curves with a Constant Internal Standard 6 Plotting Analytical Curves with a Variable Internal Standard 7 Background Correction 8 Concentration Calculations 9 Corrections for Interferences from Other Elements 10 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.

1.1 This specification covers cold-rolled carbon steel coils or strip used in the fully processed condition in magnetic lamination applications. 1.2 This steel is produced to specified maximum core-loss values and is intended primarily for commercial power frequency (50 and 60 Hz) applications in magnetic devices. Desirable core loss and permeability characteristics are developed during mill processing, so further heat treatment by the purchaser is not necessary for most uses. 1.3 Fully processed magnetic lamination steels are flat-rolled low carbon iron alloys having 1% maximum silicon and 0.4% maximum aluminum. Note-This specification is the companion to inch-pound Specification A840.

1.1 This test method covers the determination of free toluene diisocyanates in urethane prepolymers and unpigmented coating solutions.Note 1-This test method may also be useful for the determination of free isocyanate monomers of other types upon taking precautions to confirm suitability.1.2 There is no reason to believe this test method would not work for pigmented coatings.1.3 The values stated in inch-pound 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 and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 8.

1.1 This test method covers the determination of the phthalic anhydride content (Note 1) of alkyd resins and resin solutions, including those containing styrene. Note 1-This test method is not applicable for the determination of phthalic anhydride in alkyd resins containing other dibasic acids such as maleic or fumaric, or modifying agents such as urea, melamine, and phenolic resins. 1.2 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.
