Ships where electrotechnical products may be permanently or temporarily installed include - ships propelled by mechanical means, including mobile offshore units, and - ships not propelled by mechanical means, including sailing boats and life rafts. The classes defined apply to all sizes of ship from pleasure craft to trawlers, ferry boats, icebreakers, cargo ships including tankers. The areas in which ships normally navigate are - inland waterways (canals, rivers, lakes etc.), - coastal waters, and - oceans. Areas where ships navigate in ice are also included. This second edition cancels and replaces the first edition, published in 1987, and constitutes a technical revision.
