introduction
The concept is closely related to the protection of life and property safety is not compromised. This section specifies the requirements and test methods lithium battery. this Part used in IEC 60086-4 3rd Edition is in accordance with ISO /IEC Guide, also refer to all applicable national and international standards Formulated on the basis of the quasi.
Unlike conventional lithium primary batteries using an aqueous electrolyte, since they contain flammable substances. Therefore, carefully consider safety in the design, production, sale, use and disposal of lithium batteries is important. Based on the particularity of lithium batteries, Consumer lithium batteries initially small size and low power, and high-power batteries are used for the special industrial and military, the battery must be such Be replaced by professionals. IEC /T C35 at the time was in this context that the drafting of the first edition of IEC 160086-4 is. However, from the beginning of the 1980s, high-power lithium battery began widely used in the consumer sector, mainly for the power of the camera. With the significant growth in demand for high-power batteries, different production plant began production of high-power lithium battery. In this case, IEC 60086- 4 Release 2 increases the safety requirements for high-power lithium battery. This section (using IEC 60086-4 Edition 3) main goal is to make this part of lithium transport inspection items and GB 21966 Co Transfer agreement.
Appendix A is a lithium battery safety design guidelines. Appendix B is a safety design guidelines electrical appliances lithium battery for power supply. Appendix A and Appendix B is based on the Reference [18], taking into account the experience of the use of lithium batteries for cameras enacted. Security is to avoid an unacceptable risk. There is no absolute security. risk is always there. So the product, process or service is only possible There are relatively safe. Security is between the "ideal of absolute security" and "to meet the needs and take into account other factors" to seek the best balance of love Under conditions will reduce the risk to an acceptable level. ( "Meet demand" refers to a product, process or service to meet the requirements; "other factors" refers to the user benefits Factors benefit, applicability, cost efficiency and social conventions. ) Security will form different problems, it is impossible to put forward a precise set of rules and recommendations apply to all situations. But when the wise When follow the "adoption where appropriate", this section will be very coordinated safety regulations. GB 8897.4-2008/IEC 60086-4.2007
