Normally 60898-1 says 30deg as calibration temperature, why? because in most of Hot countries the ambient will be on average >40deg, also if the product used in a system the ambient in cabinet easily goes up to 50deg

@Anonymous user  - The reference ambient temperature of 30^oC for specifying rated current (In) is taken according to the installation rules standard. The current that it would deliver continuously without derating would depend on the assembly into which it is integrated. So, this is addressed as part of assembly standards and not the product standard.
