General requirements for safety of civilian primary battery

1 Scope

GB 24462-2009 is the Chinese national standard on general safety requirements for civilian used primary battery, in the field of electrical engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 15 October 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2010. Classification: ICS 29.220.10, CCS K82. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the civilian primary battery classification, security, performance requirements, marking, civilian primary batteries to buy, use, replacement and disposal guidelines, electricity Battery compartment safety design guidelines appliances. This standard applies to all types of civil-aqueous electrolyte primary batteries (alkaline and non-alkaline zinc - manganese dioxide batteries, zinc - silver oxide batteries, Zinc - nickel oxyhydroxide batteries, alkaline and neutral zinc - air batteries) and a variety of primary lithium batteries (lithium - carbon fluoride batteries, lithium - manganese dioxide battery, Lithium - thionyl chloride batteries, lithium - iron disulfide batteries, lithium - sulfur dioxide and lithium - copper oxide battery, etc.) production, testing and acceptance. This standard provides guidance for the safe use and handling of primary batteries; provide guidance for the design of electrical equipment designers battery compartment.

Appendix A

(Informative) Electric with battery compartment Design Guide A.

1 Background Growing a battery powered electrical equipment and technology, to promote primary cells mature in both structure and electrochemical properties of the battery Capacity and discharge capacity can be improved. Due to the continuous development of primary battery technology advances and people "batteries meet safety and performance Both demand "recognition, the" battery case caused by misuse of electrical equipment failure mostly due to accidental misuse the user and made Into "argument has been accepted. The following content can help designers to battery powered electric appliances Learn how to greatly reduce or eliminate battery failure. A.

1.1 Design of the battery compartment due to poor battery failure Poorly designed battery compartment can cause the battery to short circuit the battery or reverse mount. A.

1.2 Due to the potential dangers caused by battery reverse By three or more cells in series circuits (shown in Figure A.1), if there is a reverse battery, there is a latent following In danger.

a) The reverse battery to be charged;

Note. The charging current is limited by the external circuit/load.

b) The reverse battery internally generated gas;

c) the occurrence of a reverse battery discharge;

d) The reverse battery electrolyte leakage. NOTE. The battery electrolyte is harmful to human tissue. Figure A. Example 1. When a battery connected in series reverse A.

1.3 potential danger caused by a short circuit Battery short circuit will exist following potential hazards.
