Can you deviate from a mil standard?
Can you deviate from a mil standard?
(OP)
Hi all,
I ran across something today and wanted to get other engineers opinions.
I design products for a company and we routinely use mil specs to identify process parameters for our products.
Recently, I released a drawing that said process per the anodize mil-spec-xxx.xxx and below it I identified a thickness that does not fall completely within the range of the mil-spec
More specifically I said process per mil-spec -xxx.xx, and apply a coating thickness of .0004-.0008. However, the mil spec recommends a minimum of .0005.
In our business we use the anodize primarily for aluminum protection and color, the thickness range was recommended by the coating business who applies this anodize per the mil spec all day every day. When I say protection I simply mean no oxidation, it is a hand held device that does not mate with anything.
I originally thought it was no problem but I am starting to second guess myself. The mil-spec provides tons of information, and we deviate from one small portion of it to fit our needs, but we aren't military.
I feel like our drawings are the final say, so if we state process per the mil-spec but then below it we have a small deviation than its legit. Obviously we want 99% of the process to be followed so it wouldn't make sense in my opinion to do it any other way.
What is everyone's take on it?

FINISH SHALL BE PER MIL-SPEC -XXX.XX, EXCEPT WITH COATING THICKNESS OF .0004-.0008.
Then get on with your day which is clearly going pretty well otherwise if you're concerned about this.

If the anodize coating is for corrosion protection and cosmetic purposes, and there is no need to maintain tight dimensional control of the coated part surfaces, why are you specifying a .0004-.0008" min/max limit for the coating thickness rather than the .0005" min coating thickness in the standard?
