This British Standard is part 2 of a series of standards. It specifies requirements for high-performance cells and batteries with Plante type positive plate
12、s and pasted negative plates. It supersedes BS 6290-2:1984 which is withdrawn. BS 6290-1 has been withdrawn, having been superseded jointly by BS 6290-2:1999, BS 6290-3:1999, BS 6290-4:1997 and BS EN 60896-1:1992. BS 6290-3 specifies requirements for lead-acid pasted positive plate type cells and ba
13、tteries. BS 6290-4 specifies the criteria for classifying lead-acid valve-regulated cells and batteries. BS EN 60896-1 specifies general requirements for all free-venting types of stationary lead-acid cells and batteries. Guidance on safety and health aspects of the handling, installation, usage and
14、 maintenance of lead-acid stationary cells and batteries is given in BS 6133. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself con
15、fer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 13 and a back cover.
