          This recommended practice provides recommended design practices and procedures for storage, location, mounting, ventilation, instrumentation, preassembly, assembly, and charging of vented lead-acid batteries. Required safety practices are also included. This recommended practice is applicable to full-float stationary applications where a battery charger normally maintains the battery fully charged and supplies the direct current (dc) loads. However, specific applications, such as emergency lighting units, semiportable equipment, and alternate energy applications, may have other appropriate practices that are beyond the scope of this recommended practice.<br />\n
          The portions of this recommended practice that specifically relate to personnel safety are mandatory instructions and are designated by the word shall; however, all other portions are recommended practices and are designated by the word should.<br />\n
          Sizing, maintenance, capacity testing, charging equipment, dry-charged units, and consideration of other types of batteries are beyond the scope of this recommended practice.<br />\n
          This recommended practice provides a general format for the preparation of test procedures and suggests the points to be considered by technical committees in the preparation of specific instructions for the thermal evaluation of insulation systems for electrical equipment. The thermal evaluation of an insulation system involves the following thermal factors of influence:<br />\n
          a) Exposure temperature<br />\n
          b) Ambient temperature<br />\n

          This standard provides general requirements, direction, and methods for qualifying Class1E electric cables, field splices, factory splices, and factory rework for service in nuclear power generating stations. Categories of cables covered are those used for power, control, and instrumentation services, including signal and communication cables. Field cables, wires, and splices are within the scope of this standard. Cables, wires, and splices within or integral to other devices (e.g., instruments, panels, motors, etc.) should be qualified using the requirements in the applicable device standard or IEEE Std 323-1983, as appropriate. However, this standard's requirements may be applied to the wire and cable within these devices.<br />\n

However, specific applications, such as emergency lighting units and semi portable equipment, and alternate energy applications, may have other appropriate practices and are beyond the scope of this recommended practice.

Sizing, maintenance, capacity testing, charging equipment, dry charged cells, and consideration of other types of batteries are beyond the scope of this recommended practice.<br />\n
          As part of its 5-year life cycle, the Recommended Practice should be updated to be consistent with similar Recommended Practices. Recent industry practices and developments are to be incorporated.

          This standard provides general requirements, direction, and methods for qualifying Class1E electric cables, field splices, factory splices, and factory rework for service in nuclear power generating stations. Categories of cables covered are those used for power, control, and instrumentation services, including signal and communication cables. Field cables, wires, and splices are within the scope of this standard. Cables, wires, and splices within or integral to other devices (e.g., instruments, panels, motors, etc.) should be qualified using the requirements in the applicable device standard or IEEE Std 323-1983, as appropriate. However, this standard's requirements may be applied to the wire and cable within these devices.<br />\n

          This recommended practice provides recommended design practices and procedures for storage, location, mounting, ventilation, instrumentation, pre-assembly, assembly, and charging of vented lead-acid batteries. Required safety practices are also included. This recommended practice applies to all stationary applications. However, specific applications, such as emergency lighting units and semi portable equipment, and alternate energy applications, may have other appropriate practices and are beyond the scope of this recommended practice. The portions of this recommended practice that specifically relate to personnel safety are mandatory instructions and are designated by the word shall; all other portions are recommended practices and are designated by the word should. Sizing, maintenance, capacity testing, charging equipment, dry charged cells, and consideration of other types of batteries are beyond the scope of this recommended practice.<br />\n
          As part of its 5-year life cycle, the Recommended Practice should be updated to be consistent with similar Recommended Practices. Recent industry practices and developments are to be incorporated.
