"...how the part is made?" -> the manufacturing process and technique? Stuff from the ASTM has a little of this, but are typically materials test methods used to verify the result of the manufacturing process. Otherwise 'manufacturing' standards seem to be for the assembly of equipment. For example, ASTM F2946 does not talk about how to make a pipe seal, but does cover materials selection and assembly requirements for some types of seals for plastic pipe joins.
There are common tests like melt-flow index that can be done pre and post injection to verify the chemical changes of thermoplastic polymers resulting from the molding process. These test methods, and the myriad stuff in the UL746 series, could be indicative of the effectiveness of the manufacturing process, whether injection molding or AM. Some of the environmental standards indirectly effect the manufacturing process by eliminating or encouraging a process due to chemical restrictions of resultant by-products. Then there is UL, which seems to have dived into AM during past several years; they have AM manufacturing process and technique audits as part of their FUS. They seem to be running the ASTM F42 committee. Do not know what TC261 has done lately, but both have been active for 5 to 15 years. Travelers' Insurance is not saying anything new, they are just now realizing the size and breadth of the AM market and want a piece of the pie of something that has been growing for about 20 years.

Consider the Y capacitor. It must comply with the requirements in IEC 60384-1. Type and routine tests. Same as for a finished product. Supposedly, routine tests address the consistency of how the part or product is made.
