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 inter-
ested in a subject for which a Technical Committee has been set up has the right to be repre-
sented on that Committee. International organizations, governmental and non-governmental,
n 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 2301 was drawn up by Technical Committee ISO/TC 55, Sawn
timber and sawlogs, and circulated to the Member Bodies in June 1971.
It has been approved by the Member Bodies of the following countries:
Iran Romania
Australia
Belgium Ireland Spain
Italy Sweden
Canada
Czechoslovakia Netherlands Thailand
New Zealand Turkey
Egypt, Arab Rep. of
Finland Norway United Kingdom
Poland U.S.S.R.
France
Germany Portugal Yugoslavia
The Member Bodies of the following countries expressed disapproval of the document on
technical grounds :

IS0 (Organisation Internationale de Normalisation) est une federation mondiale d’orga-
nismes nationaux de normalisation (Comites Membres ISO). L’elaboration de Normes
Internationales est confide aux Comites Techniques ISO. Chaque Comite Membre interesse
par une etude a le droit de faire partie du Comite Technique correspondant. Les organisa-
tions internationales, gouvernementales et non gouvernementales, en liaison avec l’IS0,
participent egalement aux travaux.
Les Projets de Normes Internationales adopt& par les Comites Techniques sont soumis
aux Comites Membres pour approbation, avant leur acceptation comme Normes Inter-
nationales par le Conseil de 1’ISO.
