This looks like induction. I am not aware of any standards that exist, perhaps someone else is.
When dealing with induction you must ask yourself; why is this happening? And, does it need to be repaired?
The why it is happening, is usually due a combination of the use of ferromagnetic materials, and the way the electrical components are installed.
The does it need to repaired is a bit more difficult, but I would say that if it is not a risk of damage to personnel, or materials, then it does not need anything more than monitoring. Your component looks like is is not something that anyone is likely to touch, so there is a very low risk of anyone burning themselves, also the temperature is not that high (assuming your measurement is good). Also as the temperature is not that high, I would not expect any damage to the metal itself, so there should be little risk of damaging the structure. You should highlight the problem to the engineer in charge and let him make the final decision.
