Blair, I wish that what you stated was true for aerospace. I have a customer that insists on Mil-Std-2000C and other old specs. Despite my best efforts to indicate that we should not build product to a cancelled specification, the customer refuses to change the contract language. Apparently, you know of some clause where it is my option to make this call. So, have you had success with a customer who says build it to "X" where you come back and say, "No, we're going to build it to 'Y'"? Just curious, Bill Kasprzak Moog Inc.

It is entirely the option of the organization to determine which version of the standard to use - the one called for in the contract or the latest version or superseded standard. However, if you are going to do this, I would recommend that you let your customers know this when they place an order with the old standard called out.

If the production-drawing states "PCB shall be produced according to to MIL-P-55110D" does it mean that the board manufacturer has the freedom to use the replacement specification ? The specific issue is that Mil-P-55110 D does not allow exposed fibers, whereas Mil-PRF-31032 does allow this (with some restrictions of course), but I assume there are more diffferences between these two specs.
