Part Numbering
Part Numbering
(OP)
Hello,
I'm new this forum and have a question about part numbering. Here we go.
Our company at one time bought a couple of smaller companies and had a problem with overlapping in the numbering system. There fix was to take all the drawings of these two companies and stamp i.e. "H" for Hardware in front part numbers in the title block of the drawing. Here's the problem................They did not create an ECO for these changes and now it's creating some trouble. It seems that that the customers are complaining that we change the overall part number of that document without an ECO, which I agree 110%. What I need from you is where and what standard is this documented in that I can show management that this was the wrong way to do this witout doing an ECO change. I looked at MIL-STD-100 and it said it was superceded by all the ASME standard series. I pulled ASME Y 14.100-2000 and in the process of reviewing it. Can you please help me and point out some other specifications?
This breaks all the rules of Configuration Management 101!
Thanks in advance,

RE: Part Numbering
We did do/are doing a similar thing. We bought a company and they had their own part numbers. When we merged them into our facility, we assigned all of their parts one of our part numbers in our MRP system only. We are now adding a block to all of their drawings with our part number below theirs and filing all of the drawings in our viewing system by our part numbers. They only cross references are in the MRP item master.
