MIL-C-5541D question: Is Class 1A Clear?


Q. Is there any type of color specifically per MIL-C-5541D Class 1A? Our customer returned to us the quite a number of part since they said we coated them wrongly. In the specs it's Alchromed, what we did was clear chromate. Please advice, thanks!

A. Unless otherwise specified, parts processed per Mil-C-5541E or the more current revision, Mil-DTL-5541 [link is to free spec at Defense Logistics Agency, dla.mil]F (type I) shall be gold (yellow) in color.

Need copy of MIL-DTL-5541 D

May 29, 2020

Q. I have a drawing that calls out MIL-DTL-5541 D (yes, I know, don't call out spec revs...moot point now). I cannot locate a copy of Rev D, and I'm not sure about the switch from MIL-C-5541 to MIL-DTL-5541, so it may be MIL-C-5541 D. Can anyone point me to a copy of Rev D? It should be available for public consumption.

Thanks for any help.

A. Hi Kelly.
I believe the history is MIL-C-5541D was superceded by MIL-C-5541E in Nov. 1990, then superceded by MIL-DTL-5541F in July 2006. Unfortunately I don't have a copy of D, not know where to get one.
