FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable

-2- 21A/791/CDV
1 IEC 61951-1 4 Edition Amendment
3 Change to 2 Rationale: IEC 62902 should be added to normative references.

4 Change to 3 Rationale: Trickle charge definition should be added to help user understanding.

5 Change to 5.3.1, 5.3.2 Rationale: Marking of registered trademark should be added after

6 name and identification.

7 Change to 5.3.3 Rational: Marking symbols for identification of the chemistry according to IEC

8 62902 should be added.

9 Change to Table 5 in 7.3.2.2 Rationale: The table should be divided into small prismatic cells

10 and cylindrical cells. In small cylindrical cell, J and JT designations should be separated from

11 “M/MT/MU” because there are difference of discharge characteristics between M cells and J

12 cells.
13 Change to 7.5.1.3 Rationale: IEC designations should be used.

14 Change to 7.8 Rationale: The term “pressure relief feature” is more accurate for this test than

15 “safety device operation” since it describes a specific function.

16 Change to 7.12.1 Rationale: Note should be added to clarify that internal resistance

17 measurement is not required.

18 Change to 7.12.2 Rationale: Formula should be corrected, and units of measurement should

19 be clarified. Abbreviated term “RMS” is unusual. It should be changed to “root mean square”.

20 Change to 7.12.3 Rationale: Formula should be corrected, and units of measurement should

21 be clarified.

22 Change to Table 31 in 10.3 Rationale: “as agreed” should be changed to footnote “a” in order

23 to add detail.
