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 ISO, 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 5079 was developed by Technical Committee
ISO/TC 38, Textiles, and was circulated to the member bodies in March 1976.
It has been approved by the member bodies of the following countries :
Australia Hungary Poland
Belgium India South Africa, Rep. of
Brazil Ireland Spain
Sweden
Bulgaria Italy
Chile Korea, Rep. of Switzerland
Czechoslovakia Mexico Turkey
Denmark Netherlands United Kingdom
Finland New Zealand U.S.S. R.
France Norway
Germany Philippines
No member body expressed disapproval of the document.

AVANT-PROPOS
L’ISO (Organisation internationale de normalisation) est une fédération mondiale
d‘organismes nationaux de normalisation (comités membresde I’ISO). L’élaboration
des Normes internationales est confiée aux comités techniques de I‘ISO. Chaque
comité membre intéressé par une étude a le droit de faire partie du comité technique
correspondant. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec I’ISO, participent également aux travaux.
Les projets de Normes internationales adoptés par les comités techniques sont
soumis aux comités membres pour approbation, avant leur acceptation comme
Normes internationales par le Conseil de I’ISO.
La Norme internationale IS0 5079 a été élaborée par le comité technique
ISO/TC 38, Textiles, et a été soumise aux comités membres en mars 1976.
