Abstract
BRITISH STANDARD SPECIFICATION NO. 1335 ; 1946 (Publications Sales Department, British Standards Institution, 28 Victoria Street, London, S.W.I. 2s. post paid) prescribes the minimum rating of air-depolarized-type primary cells on continuous discharge and gives the methods of test on which the rating is based. An air-depolarized cell is defined as a primary cell with two electrodes, one mainly of carbon and the other of zinc, in an electrolyte of ammonium chloride, or other salts, or caustic soda, and in which the depolarization is mainly effected by air, to which free access must be given. A nomenclature is prescribed for the designation of the cells, a letter representing the type, and a number the size of cell. The letter code to be used consists of : A, D, W,R, S, and C , for air-depolarized, dry, wet, round, square and caustic soda, cells respectively. The quality of the materials to be used, the dimensions of the electrodes, containers, connecting wires and terminals of the cells are also specified in detail.
