BS EN ISO 16664:2017 describes factors that may influence the composition of pure gases and homogeneous gas mixtures used for calibration purposes. This document only applies to gases or gas mixtures that are within the "utilization period". It provides the following guidelines for the handling and use of calibration gas mixtures: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 of a gas mixture, taking into account the gas composition uncertainty given on the certificate and the user's measurement uncertainty.Cross References:ISO 472:2013 ED4ISO/IEC GUIDE 98-3:2008 Ed 1ISO/IEC Guide 99:2007ISO 6142-1:2015ISO Guide 35:2006ISO 7504:2015 ED3ISO/IEC 17025:2005GUM: 1995VDI 3490 Blatt 3:1980VIMIGC 161/16/EAll current amendments available at time of purchase are included with the purchase of this document.
