IEC 60092-305 has been prepared by JEC Technical Committee No. 18: Electrical Installations in Ships.
It forms a part of IEC Publication 92, which deals with electrical installations in ships.
The first edition of this publication was published in 1957.
A second edition consisted of six parts and was published in 1964 (Publication 92-1) and in 1965 (Publications 92-2, 92-3, 92-4, 92-5 and 92-6).
This third edition supersedes the second edition with the exception of Chapter X of Publication 92-3: Part 3: Cables (construction, testing and installation), which is under consideration. (Please see therefore the latest edition of the Catalogue of Publications.)
The series consists of the following publications:
Publications Nos. 92-101: Electrical Installations in Ships,
Part 101: Definitions and General Rcquiremezns.
92-201: Part 201: System Design—General.
92-202: Part 202: System Design — Protection.
92-301: Part 301: Equipment — Generators and Motors.
92-302: Part 302: Equipment Switchgear and Coritrolgear Assemblies.
92-303: Part 303: Equipment Transformers for Power and Lighting.
92-304: Part 304: Equipment — Semiconductor Convertors.
92-305: Part 305: Equipment — Accumulator (storage) Batteries.
92-306: Part 306: Equipment — Luminaires and Accessories.
IEC Publication 92: Electrical Installations in Ships, forms a series of international standards for electrical installations in sea-going ships, incorporating good practice and co-ordinating as far as possible existing rules.
These standards form a code of practical interpretation and amplification of the requirements of the International Convention on Safety of Life at Sea, a guide for future regulations which may be prepared and a statement of practice for use by shipowners, shipbuilders and appropriate organizations.
1. Scope
IEC 60092-305 is applicable to accumulator (storage) batteries which arc installed permanently in position for use in ships.
This standard is not applicable to batteries of the portable type.
6.1 For floating senice or for any other conditions where the load is connected to the battery while it is on charge, the maximum battery voltage under any conditions of charge shall not exceed the safe value of any connected apparatus. The voltage characteristics of the generator or generators, semiconductor convertor or semiconductor convcrtors, which will operate in parallel with the battery, shall be suitable for each individual application. Where apparatus capable of operation at the maximum charging potential is not available, a voltage regulator or other means of voltage control shall be provided.
6.2 When a battery is floated on the line with a resistor in series, all connected apparatus shall be capable of withstanding the line voltage to earth or be disconnected. For systems above 55 V it is recommended that a suitable warning plate be fitted stating: “Disconnect charging system before working on any circuit connected to the battery”.
6.3 Where the voltage of an emergency-lighting battery is the same as that of the ship’s d.c. supply, the battery may be arranged for charging in two equal sections, a charging resistor being provided for each section.
Alternatively, a booster generator may provide charging voltage. With either method, the arrange.IEC-60092-305-1980
