AIS SART: A Search And Rescue Transponder/Transmitter (SART) is a self-contained device intended for emergency use at sea. The SART shall be capable of indicating the location of a vessel in distress on the assisting vessel’s radar or AIS (Automatic Identification System).
Imo req:  The AIS-SART should: 

1 be capable of being easily activated by unskilled personnel.

2 be fitted with means to prevent inadvertent activation.

3 be equipped with a means which is either visual or audible, or both visual and audible, to indicate correct operation; 
4 be capable of manual activation and  deactivation; provision for automatic activation may be included:
5 be capable of withstanding without damage drops from a height of 20 m into water.
6 be watertight at a depth of 10 m for at least 5 min.

7 maintain water tightness when subjected to a thermal shock of 45°C under specified conditions of immersion;

8 be capable of floating (not necessarily in an operating position) if it is not an integral part of the survival craft;

9 be equipped with buoyant lanyard, suitable for use as a tether,if it is capable of floating;

10 not be unduly affected by seawater or oil.

11 be resistant to deterioration in prolonged exposure to sunlight.

12 be of a highly visible yellow/orange colour on all surfaces where this will assist detection.

13 have a smooth external construction to avoid damaging the survival craft.

14 be provided with an arrangement to bring the AIS-SART antenna to a level of atleast 1 metre above sea level, together with illustrated instructions; 

15 be capable of transmitting with a reporting interval of 1 minute or less.

16 equipped with an internal position source and be capable of transmitting its current position in each message; and 

17 be capable of being tested for all functionalities using specific test information.

2.2 The AIS-SART should have sufficient battery capacity to operate for 96 h within a 
temperature range of -20°C to +55°C, and to provide for testing of the functions on the 
equipment.  The AIS-SART should have an unique identifier to ensure  the integrity of the 
VHF data link. 

2.3 The AIS-SART should be so designed as to be able to operate under ambient 

temperatures of -20°C to +55°C.  It should not be damaged in stowage throughout the 
temperature range of -30°C to +70°C.  

2.4 The AIS-SARTs should be detectable at a range of 5 nautical miles over water.  

2.5 The AIS-SART should continue transmission even if the position and time synchronization from the positioning system is lost or fails. 

2.6 The AIS-SART should transmit within 1 minute of activation.
