Scope
This specification establishes the performance requirements for non-chromated materials used for surface preparation of metallic aircraft surfaces prior to applying organic coatings.
Rationale
The current AMS and Mil specifications for pretreatment prior to painting do not cover non-chromated pretreatments. Users have requested an industry specification to cover these new technologies and the move towards non-chromated materials in our industry. There are at least four manufacturers and a dozen users interested in having this specification and a QPL approved to control these materials.

Issuing Committee
AMS G8 Aerospace Organic Coatings Committee
The AMS Committee G-8, Aerospace Organic Coatings, provides a forum to address common concerns such as application, corrosion, environmental compliance, material compatibility, OSHA requirements, performance requirements, specifications, surface preparation, and test methods. The three primary areas of activity are: 1. Writing and Maintaining Specifications 2. Cooperative Testing 3. Information Sharing and Networking

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
