ISO 13643-2:2013 pdf download.Ships and marine technology一Manoeuvring of ships-Part 2:Turning and yaw checking.
This part of Iso 13643 defines symbols and terms and provides guidelines for the conduct of tests to give evidences about the turning ability and the yaw containment of surface ships, submarines, and models. It is intended that it be read in conjunction with ISO 13643-1.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
turning circle test
manoeuvring test to determine the ship’s turning characteristics due to application of manoeuvring devices during the period of transient motion and the ensuing steady turn depending on initial speed, rudder angle or equivalent, and direction of turn
3.2
accelerating turn test
manoeuvring test to determine the ship’s behaviour when accelerating from stand-still and simultaneously applying the manoeuvring devices hard over
3.3
thruster turning test
manoeuvring test to determine the capability to turn a ship at zero speed by using its thrusters and to determine the limiting speed at which no more turning effect from bow thrusters can be obtained
Note 1 to entry: This test is relevant to all types and arrangements of tunnel- or azimuth-thrusters. However, dynamic positioning or traversing tests are beyond the scope of this part of ISO 13643.
3.4
zig-zag test
manoeuvring test to determine the ship’s turning and yaw checking ability depending upon initial speed, the amount of manoeuvring devices effect applied, and execute change of heading at which the manoeuvring device is applied in the opposite direction (execute change of heading)
3.5
course change test
manoeuvring test to determine the ships capability to change heading by a given angle by use ot the manoeuvring devices
3.6
parallel track test
manoeuvring test to determine the behaviour of the ship steering to a parallel track by applying manoeuvring devices and subsequently applying the manoeuvring devices in the opposite sense
3.7
person overboard test
manoeuvring test to determine the change of heading at which the ship is steered back to the reciprocal of its initial track by applying manoeuvring devices hard over.ISO 13643-2 pdf download.
