22、TAINING ALKALINE OR OTHER NON-ACID ELECTROLYTES SEALED NICKEL-CADMIUM PRISMATIC RECHARGEABLE SINGLE CELLS 1 General 1.1 Scope This International standard specifies marking, tests and requirements for sealed nickel- cadmium prismatic secondary single cells. NOTE In this context “prismatic” refers to

23、cells having rectangular sides and bases. Where 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 takes precedence. 1.2 Normative references The following referenced documents are in

27、ard, the definitions contained in IEC 60050-486 and the following apply. 1.3.1 sealed cell cell which remains closed and does not release either gas or liquid when operated within the limits of charge and temperature specified by the manufacturer. The cell is equipped with a safety device to prevent

28、 dangerously high internal pressure. The cell does not require addition to the electrolyte and is designed to operate during its life in its original sealed state 1.3.2 nominal voltage the nominal voltage of a sealed nickel-cadmium rechargeable single cell is 1,2 V 1.3.3 rated capacity quantity of e

29、lectricity C 5Ah (ampere-hours) declared by the manufacturer which a single cell can deliver when discharged at the reference test current of 0,2 I tA to a final voltage of 1,0 V at +20 C after charging, storing and discharging under the conditions specified in clause 4 1.4 Parameter measurement tol

30、erances The overall accuracy of controlled or measured values, relative to the specified or actual values, shall be within these tolerances: a) 1 % for voltage; b) 1 % for current; c) 2 C for temperature; d) 0,1 % for time; e) 1 % for capacity. These tolerances comprise the combined accuracy of the

31、measuring instruments, the measurement techniques used, and all other sources of error in the test procedure. For assistance in selecting instrumentation see IEC 60051 for analogue instruments and IEC 60485 for digital instruments. The details of the instrumentation used shall be provided in any rep

33、e (M); high rate of discharge (H); very high rate of discharge (X). NOTE These types of cells are typically but not exclusively used for the following discharge rates L up to 0,5 I tA, M up to 3,5 I tA, H up to 7,0 I tA, X up to and above 7,0 I tA. This group of three letters shall be followed by a

34、group of figures indicative of the rated capacity of the cell in ampere-hours. Example: KCH15. 2.2 Cell termination This standard does not specify cell termination. 2.3 Marking Each cell shall carry durable markings giving the following minimum information: designation as specified in 2.1, (in addit

35、ion, it is permissible for a manufacturer to use his own type designation); name or identification of manufacturer or supplier; positive terminal: either a red washer or an indented or raised symbol, (see graphical symbol 5005 of IEC 60417). 2.4 Safety recommendations The manufacturer shall provide

36、recommendations for the safe handling of the cell. See also IEC 61438.
