FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 member bodies). The work of developing
International Standards is carried out through IS0 technical committees. Every
member body interested in a subject for which a technical committee has been set
UP has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with KO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the IS0 Council.
International Standard IS0 6141 was developed by Technical Committee
ISO/TC 158, Analysis of gases, and was circulated to the member bodies in
November 1977.
It has been approved by the member bodies of the following countries :

Ireland Spain
Czechoslovakia Mexico Turkey
Egypt, Arab Rep. of Netherlands United Kingdom
France Poland USA
