BRIEF HISTORY
The IS0 Recommendation R 949, Cauliflowers - Guide to cold storage, was drawn up by
Technical Committee ISO/TC 34, Agricultural food products, the Secretariat of which is held by
the Magyar Szabvinyügyi Hivatal (MSZH).
Work on this question by the Technical Committee began in 1963 and led, in 1966, to the
adoption of a Draft IS0 Recommendation.
In April 1967, this Draft IS0 Recommendation (No. 1229) was circulated to all the
IS0 Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial
nature, by the following Member Bodies :
Australia Iran Romania
Bulgaria Israel Thailand
Colombia Korea, Rep. of U.A.R.
Czechoslovakia Netherlands United Kingdom
France
New Zealand U.S.S.R.
Greece
Norway Yugoslavia
Hungary Poland
India Portugal
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in January 1969, to accept it as an IS0 RECOMMENDATION.

Moreover, the present IS0 Recommendation does not take account of the role played by horticultural
factors, and wastage during storage is not dealt with.
Subject to all possible restrictions arising from the fact that vegetables are living materials, the
application of the guidance contained in this IS0 Recommendation should enable much wastage in
storage to be avoided and long-term storage to be achieved in most cases.
1. SCOPE
