The described safety requirements comprise the protective measures to protect from hazards generated by the electricity, the electrolyte, and the explosive gases when using secondary batteries. In addition measures are described to maintain the
20、 functional safety of batteries and battery installations. For the electrical safety (protection against electric shock) under clause 5 this document refers to HD 384.4.41 (IEC 60364441). The pilot function of this standard is fully observed by indication of cross-reference numbers of the relevant c
21、lauses. But interpretation is given where adoption to direct current (DC) circuits is required. This safety standard comes into force with the date of publication and applies to all new batteries and battery installations. Previous installations shall conform with the existing national standards at
22、the time of installation. In case of redesign of old installations this standard applies.
