Surface chemical analysis — Total reflection X-ray fluorescence analysis of water
ISO 20289:2018 provides 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 comply with ISO/IEC 17025.

Information technology — Spatial Reference Model (SRM)
ISO/IEC 18026:2009 specifies the Spatial Reference Model (SRM) defining relevant aspects of spatial positioning and related information processing. The SRM allows precise and unambiguous specification of geometric properties such as position (location), direction, and distance. The SRM addresses the needs of a broad community of users, who have a range of accuracy and performance requirements in…
Space systems — Failure reporting, analysis and corrective action (FRACA) process requirements
This project proposes the development of a new International Standard that defines Failure Reporting, Analysis, and Corrective Action (FRACA) process requirements. This new International Standard will require an organization, group, or individual to apply a closed-loop FRACA process that is capable of effectively managing the failure risks and issues associated with its products. In addition,…

Optics and optical instruments — Field procedures for testing geodetic and surveying instruments — P...
This part of ISO17123 specifies a field procedure for the verification that a given Global Navigation Systems (GNSS) -based system and measurement procedure meets a required measurement uncertainty at the location and time of interest. The field procedure uses three-dimensional coordinates which are compared to reference coordinates. It is designed to be applicable to the technically versatile…
Vacuum technology — Vacuum gauges — Specifications, calibration and measurement uncertainties for sp...
This document defines terms related to spinning rotor gauges (SRGs), specifies the necessary parameters for SRGs, details their calibration procedure and describes which measurement uncertainties to consider when operating these gauges. This document is applicable to pressure up to 2 Pa.
