Gas analysis - Handling of calibration gases and gas mixtures - Guidelines (ISO 16664:2017)
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.
Gasanalyse - Handhabung von Kalibriergasen und Gasgemischen - Richtlinien (ISO 16664:2017)
Diese Internationale Norm beschreibt Faktoren, die die Zusammensetzung von reinen Gasen und homogenen Gasgemischen, die für Kalibrierzwecke verwendet werden, beeinflussen können. Diese Internationale Norm betrifft ausschließlich Gase und Gasgemische innerhalb ihres „Verwendungszeitraums“ unter besonderer Berücksichtigung von
der Lagerung von Kalibriergasflaschen;
der Entnahme von Kalibriergas aus Flaschen;
dem Transfer von Kalibriergas aus Flaschen zur Kalibrierstelle.
Des Weiteren enthält die Norm eine Kurzbeschreibung eines Verfahrens zur Beurteilung der Stabilität eines Gasgemischs, und sie berücksichtigt die im Zertifikat angegebene Unsicherheit der Zusammensetzung des Gases und die Messunsicherheit des Anwenders.
Analyse des gaz - Mise en oeuvre des gaz et des mélanges de gaz pour étalonnage - Lignes directrices (ISO 16664:2017)
L'ISO 16664:2017 décrit les facteurs susceptibles d'influencer la composition des gaz purs et des mélanges de gaz homogènes utilisés à des fins d'étalonnage. L'ISO 16664:2017 ne s'applique qu'aux gaz ou mélanges de gaz considérés dans les limites de la «période d'utilisation». Il donne les lignes directrices suivantes pour la mise en oeuvre et l'utilisation des mélanges de gaz pour étalonnage.
- le stockage des bouteilles de gaz d'étalonnage;
- le soutirage du gaz d'étalonnage des bouteilles;
- le transfert du gaz d'étalonnage des bouteilles vers le point d'étalonnage.
Il présente également une méthode permettant d'évaluer la stabilité d'un mélange de gaz en tenant compte de l'incertitude de la composition du gaz mentionnée sur le certificat et de l'incertitude de mesure liée à l'utilisateur.
Analiza plinov - Ravnanje s kalibracijskimi plini in plinskimi zmesmi - Smernice (ISO 16664:2017)
Ta dokument opisuje dejavnike, ki lahko vplivajo na sestavo čistih plinov in homogenih plinskih zmesi, ki se uporabljajo za namene kalibracije. Ta dokument se uporablja samo za pline in plinske zmesi znotraj »obdobja uporabe«. Podaja naslednje smernice za ravnanje z zmesmi kalibracijskih plinov in njihovo uporabo:
– skladiščenje jeklenk s kalibracijskimi plini;
– odvzem kalibracijskih plinov iz jeklenk;
– prenos kalibracijskih plinov iz jeklenk do mesta kalibracije.
Poleg tega opredeljuje metodo za ocenjevanje stabilnosti plinskih zmesi ob upoštevanju negotovosti sestave plinov, navedene v potrdilu, in negotovosti uporabnikovih meritev.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Introduction
This document uses the terms “calibration gas” for both gas mixtures and pure gases as the limiting
case of gas mixtures.
The quality of calibration gases in cylinders as certified by producers is defined by
a) the correct analyte content;
b) a known uncertainty which is appropriate for its intended use;
c) the stability;
d) the homogeneity.
During its utilization period, the quality of calibration gases is influenced by
— storage conditions at the manufacturer’s and user’s sites;
— transport conditions;
— modes of calibration gas withdrawal and transfer;
— the transfer system employed.
