Classic Ride Status

[Trakehner]

Anyone tell me how long a ride must be opened to achieve "Classic Ride" status? From what I have heard, said ride should never of been refurbished, but how long must it be in that state and opened?

I tried looking it up, but all I keep getting is info on the classic rides DLC pack. BTW, the current ride I am asking about is a high reliability coaster I made. Been opened 13 years and not one refurbishment. Thanks in advance.
