IEC 60936-2:1998 pdf download – Maritime navigation and radiocommunicationequipment and systems – Radar – Part 2: Shipborne radar for high-speed craft (Hsc)-Methods of testing and required test results.
IEC 60936-2 specifies the minimum operational and performance requirements. methods of testing and required test results as required by IMO resolution A.820 and Chapter X of the h,gh.speed craft (HSC) code. It complies with the requirements of 13.13 of the HSC code and incorporates applicable parts of 13.5 of the HSC code on radar installations. In addition it takes account of IMO resolution A.694 and Is associated with IEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence.
The HSC scenarios, as defined In annex D. apØy to equipment Intended for use on high-speed craft and to equipment which is tested to IEC 60872-1 and IEC 60872-2 and also intended for use on high-speed craft.
All texts of this standard, whose wording is identical to that in IMO resolution A.820 are printed in italics and the resolution and paragraph numbers are indicated in brackets.

The radar equipment shall provide an indication, in relation to the craft, of the position of other surface craft and obstructions and 0$ buoys, shorelines and navigational maris in a manner which will assist In navigation and in avoiding collision.
3.2.1 Equipment shall be installed in such a manner that it is capable of meeting its recommended performance standards.
3.2.2 The operator manual for the radar shall include precautions in the use of the radar under certain combinations of condiIons with regard to not performing to specification i.e. picture smearing and target tracking loss when at high speed close to targets.
3.2.3 Quality assurance
The radar shall be designed, produced and documented by companies complying with the
ISO 9000 series standards, as applicable.
3.3 (A.8203) Range performance
The operational requirement, where the radar antenna is mounted 7,5 m above sea level, is that the equipment shall give a clear indication of surface objects such as a navigational buoy with a radar reflector height of 3.5 m. having an effective echoing area of approximately 10 m at 2,5 nautical miles in the absence of clutter.
3.4 (A.8204) Minimum rang.
The surface objects specified in 3.3 shall be clearly displayed from a minimum range of 35 m up to a range of one nautical mile, without changing the setting of controls other than the range selector.
The minimum range is the shortest distance at which, using a mandatory range scale of not more than I .5 nautical miles. a stationary target ahead is still presented separately from the point representing the antenna position.
3.5 (*820,5) Display
3.5.1 (A.8205. 1) The equipment shall without external magnification provide a multi-colour daylight display with an effective radar picture diameter of not less than 250 mm.
3.5.1.1 Target echoes shall be displayed by means of the same basic colours and the echo strength shall not be displayed in different cofours.
3.5.1.2 Additional information may be shown in different colours.
3.5.2 (A.8205.2) Day and night colours shall be provided. It shall be possible to adjust brightness.
3.5.2.1 The radar picture and information shall be readable under all ambient light conditions. If a light shield Is necessary to facilitate operation of the display In high ambient levels, then means shall be provided for its ready attachment and removal.
