Auger electron spectroscopy is often capable of yielding information concerning the chemical and physical environment of atoms in the near-surface region of a solid as well as giving elemental and quantitative information. This information is manifested as changes in the observed Auger electron spectrum for a particular element in the specimen under study compared to the Auger spectrum produced by the same element when it is in some reference form. The differences in the two spectra are said to be due to a chemical effect or a matrix effect. Despite sometimes making elemental identification and quantitative measurements more difficult, these effects in the Auger spectrum are considered valuable tools for characterizing the environment of the near-surface atoms in a solid.1.1 This guide outlines the types of chemical effects and matrix effects which are observed in Auger electron spectroscopy.1.2 Guidelines are given for the reporting of chemical and matrix effects in Auger spectra.1.3 Guidelines are given for utilizing Auger chemical effects for identification or characterization.1.4 This guide is applicable to both electron excited and X-ray excited Auger electron spectroscopy.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 describes methods for determining the specimen area contributing to the detected signal in Auger electron spectrometers and some types of X-ray photoelectron spectrometers when this area is defined by the electron collection lens and aperture system of the electron energy analyzer. The practice is applicable only to those X-ray photoelectron spectrometers in which the specimen area excited by the incident X-ray beam is larger than the specimen area viewed by the analyzer, in which the photoelectrons travel in a field-free region from the specimen to the analyzer entrance, and in which an auxiliary electron gun can be mounted to produce an electron beam of variable energy on the specimen.1.2 This practice is recommended as a useful means for determining the specimen area viewed by the analyzer for different conditions of spectrometer operation, for verifying adequate specimen and beam alignment, and for characterizing the imaging properties of the electron energy analyzer.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.

This test method is designed to assess the purity of 2-mercaptobenzothiazole sulfenamide accelerators. These products are used in combination with sulfur for the vulcanization of rubber. The test method is suitable for assessing product specifications in that the property it measures is related to product performance. Since it is the primary property for comparison of product quality at different production facilities, good interlaboratory accuracy and precision is required. Based on past experience, two significant sources of error in this test method are: (1) incomplete reduction and (2) titration end point assessment. Problems in these areas can be avoided by closely following the procedure.1.1 This test method covers the determination of assay on mercaptobenzothiazole (MBT) sulfenamides. It is based on a titration of the basic amines liberated upon reduction of the sulfenamides with hydrogen sulfide gas (H2S), or 2-mercaptobenzothiazole.1.2 Any free amine (HNR2) or weak acid salts of the corresponding amine (HXHNR2) are titrated prior to reduction. This titer is used to calculate percent basic impurity (as free amine) in the sample.1.3 With the indicated modifications, this test method is applicable to all MBT sulfenamides, that is, N-cyclohexyl-2-benzothiazolesulfenamide (CBS), N,N-diisopropyl-2-benzothiazyl sulfenamide (DIBS), 2 (morpholinothio) benzothiazole (MBS), N,N-dicylohexyl-2-benzothiazyl sulfenamide (DCBS), N-tert-butyl-benzothiazole-sulfenamide (TBBS), and 4-morpholinyl-2-benzothiazyl disulfide (MBSS).1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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 specific hazard statements, see Section .

X-ray fluorescence spectrometry can provide an accurate and precise determination of metallic and many non-metallic elements. This guide covers the information that should be included in an X-ray spectrometric analytical method and provides direction to the analyst for determining the optimum conditions needed to achieve acceptable accuracy. The accuracy of an analysis is a function of the calibration scheme, the sample preparation, and the sample homogeneity. Close attention to all aspects of these areas is necessary to achieve the best results. 1.1 This guide covers guidelines for developing and describing analytical procedures using a wavelength-dispersive X-ray spectrometer.1.2 The values stated in SI 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.

This International Standard describes factors that may influence the composition of pure gases and homogeneous gas mixtures used for calibration purposes. This International Standard only applies to gases or gas mixtures that are within the “utilization period”, and it pays special attention to -storage of calibration gas cylinders; -calibration gas withdrawal from cylinders; -transfer of calibration gas from cylinders to the point of calibration. It also outlines a method of assessing the stability for a gas mixture, and takes into account the gas composition uncertainty given on the certificate and the users measurement uncertainty
