C1.2.b. What is the period of validity for a medical certificate?
The MLC, 2006 sets out maximum periods in Standard A1.2, paragraph 7, which states that, unless a shorter period is required by reason of the specific duties to be performed by the seafarer concerned or is required under the STCW, a medical certificate shall be valid for a maximum period of validity of two years unless the seafarer is under the age of 18, in which case the maximum period is one year. A certification of colour vision is valid for a maximum period of six years. As indicated these are maximums; a country could have shorter periods of validity.
