Surface chemical analysis -- Secondary ion mass spectrometry -- Calibration of the mass scale for a time-of-flight secondary ion mass spectrometer
This document specifies a method to optimize the mass calibration accuracy in time-of-flight secondary ion mass spectrometry (SIMS) instruments used for general analytical purposes. It is only applicable to time-of-flight instruments but is not restricted to any particular instrument design. Guidance is provided for some of the instrumental parameters that can be optimized using this procedure and the types of generic peaks suitable to calibrate the mass scale for optimum mass accuracy.

Surface chemical analysis -- X-ray photoelectron spectroscopy -- Procedures for assessing the day-to-day performance of an X-ray photoelectron spectrometer
This document is designed to allow the user to assess, on a regular basis, several key parameters of an X‑ray photoelectron spectrometer. It is not intended to provide an exhaustive performance check, but instead provides a rapid set of tests that can be conducted frequently. Aspects of instrument behaviour covered by this document include the vacuum, measurements of spectra of conductive or non-conductive test specimens and the current state of the X‑ray source. Other important aspects of the instrument performance (e.g. lateral resolution) fall outside the scope of this document. The document is intended for use with commercial X‑ray photoelectron spectrometers equipped with a monochromated Al Kα X‑ray source or with an unmonochromated Al or Mg Kα X‑ray source.

Chemical disinfectants and antiseptics - Differentiation of active and non-active substances
This document defines how to exclude or confirm that an excipient in a biocidal product is an active substance within the frame of the European Biocidal Product Regulation and other regulations.

Gas analysis -- General quality aspects and metrological traceability of calibration gas mixtures
This document provides requirements and guidelines on the necessary quality assurance required to produce calibration gas mixtures that are demonstrably stable and comparable. It shows that this is achieved by demonstrating that the composition of the calibration gas mixture is metrologically traceable to the SI. This document shows that calibration gas mixtures can be prepared according to methods that have measurements that are completely described in SI units. It describes procedures for verifying that the composition of such gas mixtures is correct within the stated measurement uncertainty. Guidance is given as to how to conduct the evaluation of uncertainty in these procedures. This document also shows how a calibration gas mixture with unknown composition can be calibrated by reference to traceable standard gas mixtures. This document covers the commonalities and differences of quality management schemes in use by producers of calibration gas mixtures, most notably those described in ISO/IEC 17025 and ISO 17034. These systems lead to gas mixtures with different characteristics, and this document explains these differences and their implications. Calibration gas mixtures, as prepared and certified for composition in accordance with this document, are used for the calibration of equipment, the performance evaluation of methods, measurement procedures and equipment.
