Optional use of ECDIS
current versions of IHO S-52 and IHO S-57 and associated appendices. The IEC ECDIS
Test Standard is contained in IEC Publication 61174. In addition IEC 61174 refers to the
application of other test standards to an ECDIS. In particular to IEC 60945, containing
general requirements for robustness of the device against environmental influences and
for software design, and IEC 61162 for data interfacing.
Meeting Carriage Requirements with ECDIS
Only a type approved ECDIS operating with up to date official ENCs and with
appropriate back up may be used to replace all paper charts on a vessel.
Where official ENCs are not yet available, IMO regulations allow Flag States to authorise
the use of official raster charts (together with an appropriate folio of paper charts) - see
section below.
