Description of two types of controlled atmospheres: type 1 with slightly reduced oxygen content and more or less enriched in carbon dioxide in such a way that the sum of the contents is 21 % (V/V); type 2 in such a way that the sum of the oxygen and the cabon dioxide contents is below 21 % (V/V). Specification of the method of regulation of atmospheres, of chambers for controlled atmosphere storage, of the regulation of temperature and atmosphere, of the maintenance of the composition of the atmosphere, of checks during the keeping period, and of operations at the and of storage.
