Revision G issued
On September 12, 2011 the specification for Mil-PRF-22750 was updated to Revision G. This was the first revision in almost 20 years and changed the specification in many ways. The spec now makes distinctions for various levels of performance. Now included in the spec are designations for Types, Classes, and Grades, none of which were ever relevant in the prior revisions. Rev G has four different Types as well as two Classes and two Grades. The callout for this item now has become very complicated. For example, a typical Hentzen product PIN number, Part or Identifying Number, would read as follows: M22750-2-H-A-001G-17925, meaning it is Type II, Class H meaning high solids, solvent base formulation as opposed to Class W which would be water base formulation, and Grade A, for this one gallon kit of color 17925. Here is the link to the latest revision of this spec for those who are interested in all of the details.
