I do the purchasing and quoting for a small job shop and am trying to find out what 5.3.1.2. or 5.3.2.2 of MIL-STD-171 is. I would greatly appreciate any help.

Greg, you can find Military Specifications on the web pretty easily- currently http://assist.daps.dla.mil/quicksearch/ works, but if the DoD changes it just type in "Military Specification" in Google, and you'll get there. Anyway, in Revision E, paragraph 5.3.1.2 deals with Chemical Agent Resistant Coatings (CARC), and there is no 5.3.2.2. Perhaps your request refers to an earlier revision of Mil-Std-171.

MIL-STD-171E concerns Phosphate finishes for iron & low alloy steels. 5.3.1.2. is Phosphate Type M per DOD-DTL-16232 [link is to spec at TechStreet, German only] Class 2, is with a supplementary treatment with lubricating oil conforming to MIL-L-3150 & 5.3.2.2. is Phosphate Type Z per DOD-P-16232 Class 2 with preservative conforming to Mil-PRF-16173 [link is to spec at TechStreet], grade 3 or MIL-L-3150 (as alternate for very small parts) Hope this helps.

Marie M's answer is the correct one! Mil STD 171 is the standard for industry to coat bare metals to a certain specification for the Department of Defense. MIL-STD-193 is the standard for CARC.

QUESTION IS WHAT IS THE DIFFERENCE IN THE 2 VS 3 IN 5.3.1.2 MIL-STD-171 AND 5.3.1.3
Thinking differance is .2 for oiling parts and .3 for not oiled parts to be painted?

Sorry, I was lost at first, as Lee was, because this spec has a section 5.3.1.2, but that's not not what you are talking about . . . you are talking about finish number 5.3.1.2 and 5.3.1.3, from Table V
Although phosphated parts thar not oiled usualy get painted, I don't see this specification demanding that they be painted.
