This specification details the general materials performance, compatibility, and processing information requirements for international company approval of electrodeposition (ELPO) primers.

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose/Material Description.

Materials qualified to this standard shall meet the performance requirements shown in Appendix A, Table A2. Additional testing and any exceptions to the requirements detailed herein are noted in the Appendix. Suppliers shall demonstrate the technology as being production capable to reduce undue risk prior to release in a production facility. Any material development issues, such as chemical or performance values that fall outside of specified ranges, should be discussed with the appropriate ELPO engineer for resolution. Material should successfully complete a production trial in a target facility prior to release for other facilities. Plant-specific tests should be performed after generic approval is received. An example of items evaluated in plant-specific testing includes GM sealers and sealing compounds.

Applicability.

This specification applies to medium, high-build and Hyper-throw materials for use on vehicles and space frames. These primers are intended to provide corrosion and chip resistance and may or may not be intended for subsequent coating for appearance purposes. These coatings shall perform over bare Cold Rolled Steel (CRS), Electrogalvanized (EG) coated steel, Hot Dip Galvanized coated steel (HDG), Galvannealed (Zinc-Iron Alloy (ZnFe)) and Aluminum substrates (Al).

Remarks.

Not applicable.
