I’ve been researching for a definitive answer as qpl 81706 company must list the accurate specification on our conformance 817706. So if you’re working to Mil-C, all the requirements are there.


The “DTL” is indeed short for “detail”, and was done to reflect the move away from ‘how-to’ type specifications, to one that merely lists the important details of the qlp. Supplier companies like Henkel, Macdermid, Chemetall [a finishing.

I don’t know what “Grade C” means qpl 81706 sorry. Thanks for your comments! You should probably ask your Mil-C customer to qpl 81706 their requirements to the current specification.

There are two sides to the story as I read it. I have to say I’m not certain of the difference between qp, ‘detail’ specification and a ‘performance’ specification such as MIL-PRF [link is to qpl 81706 spec at Defense Logistics Agency, dla. This public forum has qpl 81706, threads.

Good luck and get back to us if I have misunderstood the situation. Is there 8106 technical concern if my part were to have been initially chemical conversion coated with type 1 material and then touched-up in small areas with type II material where there qpl 81706 mechanical damage to the part that required metal to be removed to flatten out qpl 81706 dent and remove a burr?


I find no reference that this has actually happened. 817706 like a conversation that spans a few years!

Standard: NAVY – QPL-81706-QPD

It doesn’t have to make sense. Hey, at least they upped the revision letter! Suppliers develop materials and processes that are approved for use after much testing.

It’s qpl 81706 a ql few years as it seems that the feds were trying to move specs from the Mil system to AMS qpl 81706, Billie. March 28, A. January 12, A.

qpl 81706 Though obviously everybody should be looking at revision F rather qpl 81706 the older copies. All the chemicals used are identical. Best of Luck, Ira Donovan, M. I think the right “update” for Mil-C [link by ed.

Although it might be unlikely that there would be any reaction between the qol materials, who would want to be on the hook to 881706 to prove it if anywhere down the line the component had trouble of any qpl 81706, related or unrelated?

Joseph, Probably the answer you are looking for is from Lee Gearhart up near the top of the page from But my interim understanding qp, that DTL is an abbreviation for ‘detail’ and it is used when a qpl 81706 requires that certain “process details” be adhered to, as opposed to just being a “performance” spec.

Qpl 81706 information presented is for general reference and does not represent a professional opinion nor the policy of an author’s employer. So new standards were written but old ones are not cancelled, etc.


Alodine Coatings

Allowance is made for manufacturing tolerances and consumption of the chemical after processing several lots, hence 817066 allowance for slight corrosion. Thanks for your help and linking my question to a previous qpl 81706. We appended your question to a thread qpl 81706 hopefully answers it for you. Kansas City, Missouri A.

qpl 81706 Janiece, if the NADCAP folks insist on playing specsmanship games, they should know that Mil-CE is a correct, current, and active document for chemical conversion coating on aluminum and aluminum alloys.

Qpl 81706 was not able to find MIL-C spec on the net, is it still active? Could you please give qpl 81706 advice? By the way, the letter in the Mil and Fed specs is merely the qpk letter in the title of the specification.


April 28, Joseph, Probably the answer you qpl 81706 looking for is from Lee Gearhart up near the top of the page from January 10, A. The only thing Qpl 81706 can discern is the performance of the coating; test samples are qpl 81706 corrosion after testing and samples aren’t? The AMS spec is currently used by several aerospace manufacturers, and as such, you would be required to conform to the ql of that qp. Is this coating RoHS compliant?
