There could be many. Generally, the code to be used for repairs should be the same code used for original fabrication of the system. Or, the Engineer accepting responsibility for the repair can select any code/spec agreed upon with the customer.
What comes to my mind, or anybody else's except the client, is irrelevant. Whoever is going to be responsible for the repair has to pick an applicable code/spec or work in accordance with the code/spec chosen by the owner.
