Natural gas - Guidelines to traceability in analysis (ISO 14111:1997)

Migrated from Progress Sheet (TC Comment) (2000-07-10): See mail from P. Pieters dated on 98-03-31 (BL)

Erdgas - Leitlinien für die Rückführbarkeit in der Analytik (ISO 14111:1997)

Diese Internationale Norm enthält allgemeine Leitlinien für die Umsetzung und Anwendung von Konzepten zur Rückführbarkeit in der Erdgasanalytik. Ihr Zweck besteht darin, die Grundlagen für die Entwicklung spezifischer Verfahrensanweisungen zur Rückführung in anderen Internationalen Normen der Erdgasanalytik festzuschreiben. Anmerkung: Neben der Analyse von Erdgas könnte diese Internationale Norm auch für andere Bereiche der Gasanalyse und verwandte Gebiete, so z.B. Luftgütemessung, Kraftfahrzeug-Abgasanalyse und Referenzgasherstellung von Nutzen sein.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 14111 was prepared by Technical Committee
lSO/TC 193, Natural gas, Subcommittee SC 1, Analysis of natural gas.
Annexes A to C of this International Standard are for information only.

Introduction
At a time when assurances of measurement accuracy in natural-gas
analyses are increasingly being sought, every analytical chemist
responsible for the design and operation of systems used in such analyses
needs to be aware of, and adopt, suitable
