Certificate of Conformaty

[komatias]

Hi Guys,

Is it normal to ask for a C of C for a machined part? We are not ISO registered.

Of course it is normal. It states that you are abiding by the customers drawing and providing them with what they paid for and are liable for any discrepancy. Iso or not makes no difference. You basically put in writing that the parts you made are good. Ideally you will have inspected a number of parts from the batch and ensured they are to tolerance according to the drawing. How many of the batch you inspected should have been discussed before you took the order.
