Visual Inspection Coupons for Chromate Conversion

Are there coupons available for purchase that show the range of acceptable conditions when performing visual inspection of Chromate conversion coated aluminum parts per MIL-DTL-5541 [affil link or DLA]?

Ed. note: Sorry, this RFQ is outdated so private contact is no longer available, but public technical replies are still welcome! No public brand/source suggestions please ( huh? why?)

Hi, J. If they are available someone else will have to tell you about them because I have never seen them. I imagine that both the buyer and the plating shop would have to sign off that the coupons properly represent their understanding of Mil-DTL-5541, but it sounds like a good idea.

In fact, this sounds like a good idea for a thousand different finishes, since we have questions about "aesthetic standards" here every week. Even in the worst of times there are ways for entrepreneurs to start a whole new market -- I'm looking forward to hearing about these coupons soon :-)
