ASME reference related to defining Process versus end results on drawings help

I recall seeing something in ASME documentation regarding not specifying a process to acomplish a desired result unless the process were critical to the end result.

Does anyone know where that is in ASME documents, if at all?

I am having a heated discussion regarding the use of 'Tinned' on drawing to indicate a wire stripped insulation is to recieve 'Tinned Coating' in order to prevent multiple strand wires from fraying.

My preference is to note 'Tinned' in dimension as a subfix. I am not concerned with method of tinning, either with solder iron or dipping in pot with molten solder. We have multiple manufacturing facilities and Vendors that do the tinning.

We have for decades used 'Tinned' as part of dimension at strip area for noting this. We have recently had a facility miss this process, which resulted in a return of an order from a customer. A sales engineer is insisting that we modify that particular drawing to not 'Tin Dipped' in place of 'Tinned' and I am reluctant to do that on a case by case basis.

There are notes on drawings that indicate solder composition to be used and another that indicates no damage to  wires permitted,

I would agree with your version. Tinned indicates a result without specifying method, tin dipped indicates a method/process.
