General 1.1 Scope This International Standard specifies tests and requirements for vented nickel-cadmium prismatic
25、 secondary single cells. NOTEIn this context, “prismatic” refers to cells having rectangular sides and base. When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this standard, the former shall take precede
26、nce. 1.2 Normative references The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based
27、on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards listed below.

Designation and marking 2.1 Cell designation Vented nickel-cad
36、mium prismatic secondary cells shall be designated by the letter K followed by a letter L, M, H or X which signifies: low rate of discharge (L)1); medium rate of discharge (M)1); high rate of discharge (H)1); very high rate of discharge (X)1). This group of two letters shall be followed by a group o
37、f figures indicative of the rated capacity of the cell in ampere-hours. For example: KH 185. Cells in cases of plastic material shall be designated by the letter “P” after the figures. For example: KH 185 P. 2.2 Cell termination This standard does not specify cell termination. 2.3 Marking Except whe
38、n otherwise required by the purchaser, each cell shall carry durable markings giving the following minimum information: type of cell (designation as specified in Clause 2.1; in addition, it is permissible for a manufacturer to use his own type designation); manufacturers or suppliers name; positive
