This technical standard has been based rigorously upon the performance standards of the relevant resolution A.824(19). In the course of the development of this technical standard some problems had been identified with this resolution, as detailed in document NAV 45/7/1.
7.23 The Sub-Committee also noted that MSC 71 had considered document MSC 71/20/10 (IEC) proposing that amendments to resolution A.824(19) - Performance standards for devices to indicate speed and distance be developed, to enable IEC to finalize their relevant standard in line with that resolution and had decided to include in the Sub-Committee's work programme a high priority item on "Revision of performance standards for devices to indicate speed and distance (resolution A.824(19))", with a target completion date of 1999 and also include the item in the provisional agenda for NAV 45.
7.24 The Sub-Committee considered NAV 45/7/1 (IEC), NAV 45/7/6 (United Kingdom), NAV 45/7/7 (Sweden) and MSC 71/20/10 (IEC) and after considerable discussion agreed the revised performance standards for devices to measure and indicate speed and distance, given in annex ..., for adoption by the Committee.
7.25 The delegation of Bahamas, supported by the delegations of Australia, Greece, Panama and the ICS representative, was of the opinion that the minimum requirement for devices to measure and indicate speed and distance, which are intended for general navigation, ship manoeuvring and anti-collision use, should be - "to provide information on the distance run and the forward speed of the ship through the water" only.
ADOPTION OF PERFORMANCE STANDARDS
7.26 Taking into account the above decisions, the Sub-Committee prepared draft MSC resolutions on adoption of new and amended performance standards to which the following new and amended recommended performance standards are attached:
.1 night vision equipment for high-speed craft;
.2 daylight signalling lamps; and
.3 devices to measure and indicate speed and distance,
and was of the opinion that these performance standards should apply from 1 July 2002.
