EVS-EN ISO 16315:2026

ISO 16315 specifies the design and installation of alternating current (AC) and direct current (DC) electrical systems used for the purpose of electrical propulsion and/or the electrical part of a hybrid propulsion system (system with both a rechargeable battery and a fuelled power source).

ISO 16315 applies to electrical propulsion systems operated in the following ranges either individually or in combination:

— direct current of less than 1 500 V DC,
— single-phase alternating current up to AC 1 000 V,
— three-phase alternating current up to AC 1 000 V.

Electric propulsion systems for small craft are generally designed and constructed from a number of component parts many of which can be of proprietary origin and all of the electrical and control items are interconnected by cables and operated as a system. This standard can be applied to electrical propulsion systems installed in small craft up to 24 m length of the hull.

ISO 16315:2026 text has been approved in Europe as EN ISO 16315:2026 without any changes.
