This document specifies methods for:
— determining the composition of a calibration gas mixture by comparison with appropriate reference gas mixtures;
— calculating the uncertainty of the composition of a calibration gas mixture in relation to the known uncertainty of the composition of the reference gas mixtures with which it was compared;
— checking the composition attributed to a calibration gas mixture by comparison with appropriate reference gas mixtures;
— consistency testing and outlier search in suites of calibration gas mixtures of closely related composition.
NOTE 1 In principle, the method described in this document is also applicable to the analysis of (largely) unknown samples instead of prospective calibration gas mixtures (i.e. gas mixtures which are intended for use as calibration gas mixtures). Such applications, however, need appropriate care and consideration of additional uncertainty components, for example, concerning the effect of matrix differences between the reference gases used for calibration and the analysed sample.
NOTE 2 Comparison methods based on one- and two-point calibration are described in ISO 12963.

This document specifies a chemical method for technicians working with total reflection X-ray fluorescence (TXRF) instrumentation to perform measurements of water samples, according to good practices, with a defined degree of accuracy and precision. Target users are identified among laboratories performing routine analysis of large numbers of samples, which also conform with ISO/IEC 17025. This document specifies a method to determine the content of elements dissolved in water (e.g. drinking water, surface water and ground water). This document is also applicable for determining elements in waste waters and eluates, taking into account the specific and additionally occurring interferences. This document does not specify sampling, dilution and pre-concentration methods. Elements determined using the method specified in this document can depend on the X-ray source of the instrument. This document does not specify health, safety or commercial aspects. The determinable concentrations depend on the matrix and the interferences encountered. In drinking water and relatively unpolluted waters, the limit of quantification lies between 0,001 mg/l and 0,01 mg/l for most of the elements. The range of concentrations typically lies between 0,001 mg/l and 10 mg/l, depending on the element and predefined requirements. Annex A reports an example of uncertainty calculation. Annex B provides an example report on validation of the method for TXRF analysis of water performed with instrumentation that has Mo as the X-ray source and uses Ga as the internal calibration standard. Limits of quantification of most elements are affected by blank contamination and depend predominantly on the laboratory air-handling facilities available, on the purity of reagents and the cleanliness of labware.

This document defines the following quantities commonly used to express the composition of gas mixtures:
— amount fraction and concentration;
— mass fraction and concentration;
— volume fraction and concentration.
For these quantities of composition, this document specifies methods for:
— conversion between different quantities;
— conversion between different state conditions.
Conversion between different quantities means calculating the value of the content of a specified component in terms of one of the quantities listed above from the value of the same content, at the same pressure and temperature of the gas mixture, given in terms of another of these quantities. Conversion between different state conditions means calculating the value of the content of a specified component, in terms of one of the quantities listed above, under one set of state conditions from the value of the same quantity under another set of state conditions, i.e., pressure and temperature, of the gas mixture. Gas mixture composition can be converted simultaneously between different quantities of composition and different state conditions by combination of the two types of conversion.
This document is applicable only to homogeneous and stable gas mixtures. Therefore, any state conditions (pressure and temperature) considered need to be well outside the condensation region of the gas mixture. In addition, volume concentrations can only be used if the component under consideration is completely gaseous, and for the use of volume fractions, all components need to be completely gaseous. Further restrictions of state conditions apply for approximations of compression factors using virial coefficients (see Annex A).

This document specifies information to be reported by an analyst in a datasheet, certificate of analysis, report or other publication regarding the handling, preparation, processing and mounting of specimens for surface analysis. Appropriate sample handling with adequate documentation is needed to ensure and assess reliability and reproducibility of analyses. Such information is in addition to other details associated with specimen synthesis, processing history and characterization, and should become part of the data record (sometimes identified as provenance information) regarding the source of the material and changes that have taken place since it was originated. This document also includes normative annexes that summarize important processes and common approaches relevant to sample preparation and mounting for surface analysis. The descriptions of procedures for which records and reporting are required follow the steps that an analyst would follow from receiving the samples, to cleaning or processing outside of the analysis chamber, sample mounting and then treatments in the analysis chamber. The descriptions of the processes and their implications are intended as an aid for the analyst in understanding the reporting requirements for the specialized sample-handling conditions and approaches required for analyses by techniques such as Auger electron spectroscopy (AES), secondary-ion mass spectrometry (SIMS), and X-ray photoelectron spectroscopy (XPS). The methods described are also applicable for other analytical techniques, such as total reflection X-ray fluorescence spectroscopy (TXRF), low energy electron diffraction (LEED), some types of scanning probe microscopy (SPM) including atomic force microscopy (AFM) and scanning tunnelling microscopy (STM), ultra-violet photoelectron spectroscopy (UPS) and medium- and low-energy ion scattering (MEIS and LEIS [also called ion surface scattering, ISS]) that are sensitive to surface composition. This document does not specify the nature of instrumentation, instrument conditions (e.g., calibration or vacuum quality), or operating procedures required to ensure that the analytical measurements described have been appropriately conducted.

This document specifies a method for the calibration of the sputtered depth of a material from a measurement of its sputtering rate under set sputtering conditions using a single- or multi-layer reference sample with layers of the same material as that requiring depth calibration. The method has a typical accuracy in the range of 5 % to 10 % for layers 20 nm to 200 nm thick when sputter depth profiled using AES, XPS and SIMS. The sputtering rate is determined from the layer thickness and the sputtering time between relevant interfaces in the reference sample and this is used with the sputtering time to give the thickness of the sample to be measured. The determined ion sputtering rate can be used for the prediction of ion sputtering rates for a wide range of other materials so that depth scales and sputtering times in those materials can be estimated through tabulated values of sputtering yields and atomic densities.

It applies to analyzers suitable for use in water containing liquids, ultrapure waters, fresh or potable water, sea water or other aqueous solutions, industrial or municipal waste water from water bodies (e.g. lakes, rivers, estuaries), as well as for industrial process streams and process liquids. Whilst in principle amperometric oxygen-analyzers are applicable in gaseous phases, the expression of performance in the gas phase is outside the scope of this document. This document is applicable to analyzers specified for permanent installation in any location (indoors or outdoors) using membrane-covered amperometric sensors.

IEC 61347-2-7:2011 specifies particular safety requirements for battery supplied electronic controlgear for maintained and non-maintained emergency lighting purposes. It includes specific requirements for electronic controlgear and control units for self-contained luminaires for emergency lighting as specified by IEC 60598-2-22. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision. Significant changes introduced into this third edition include:
- modification of IEC 61347-2-7 to become a standard exclusively for d.c. battery supplied electronic controlgear for emergency lighting (self-contained) IEC 61347-2-3 Annex J is intended to cover centrally supplied emergency controlgear;
- update of Clause 22 - Recharging devices;
- modification of Clause 20 battery voltage characterisation to support EBLF measurement. This to simplify and increase reproducibility of testing;
- rationalisation of requirements between IEC 61347-2-7 and IEC 60598-2-22 requirements of IEC 60598-2-22 being transferred to IEC 61347-2-7.
This publication is to be read in conjunction with IEC 61347-1:2007.

The stable isotope ratios of carbon, hydrogen, oxygen and nitrogen can be used to obtain information about the origin of bio-based feedstock and characteristics of production processes of bio-based products. However, no or limited attention for the use of the elements nitrogen and sulphur is given in this document due to the fact that these applications are not yet available.
This Technical Report provides an overview of existing applications of isotope ratio analysis of carbon, hydrogen, oxygen and nitrogen that are relevant to the analysis of bio-based feedstocks, products and production processes
