IEC60945

MARINER SYSTEMS (UK) Ltd
Marine Test Requirements based on IACS Unified Requirement E10 & IEC60945


General:   The aim is to have an agreed consolidated “worst-case” test schedule, which will meet the current
requirements of all the major Classification Societies.  The schedule will fully cover the IACS
Unified Requirement E10 and, in addition, the relevant sections of IEC60945 (latest valid revision
applies, at present this is IEC60945:2002) for ECDIS, which relate specifically to marine personal
computer products, when used within a protected environment. The schedule will not cover the
ECDIS requirements for Visual Display Units, at the present time.
