The body of the standard is clearly a product standard applying to the cells themselves, but the Scope seems to imply that the standard applies to equipment using the cells as well. In fact, the Informative Annexes A and B are worth study by equipment manufacturers planning to use the cells, and the body of the standard gives *information* on how the cells are tested and what they will withstand. But it does not, and cannot, impose requirements on equipment. -- OOO - Own Opinions Only. Try www.jmwa.demon.co.uk and www.isce.org.uk Things can always get better. But that's not the only option.
