Passivation Quality Standards & Specifications

Companies in industries such as aerospace, medical devices, and food manufacturing can’t afford to have components in their equipment that can’t withstand corrosion. That’s why EMI has gone out of its way to developing passivation services that meet the highest standards in the industry

Aerospace electropolished and passivated parts


This set of standards established by the American Society for Testing and Materials sets requirements for passivation of stainless steel parts, equipment and systems. It specifies various methods for testing the quality of the finish. While the quality standards are specific, ASTM A380 allows for different types of operations so long as the final product meets the standard requirements.

ASTM A 967

This set of standards from the ASTM is similar in that it sets forth requirements for passivation of stainless steel. The major difference is that it was inspired by – and has the net effect of replacing – QQ-P-35C, a similar set of discontinued standards produced by the U.S. Department of Defense.

AMS 2700

The Society of Automotive Engineers (SAE) has produced its own Aerospace Material Specifications standards that are unique to and heavily used by the aerospace industry. AMS 2700 is a set of passivation standards that is very similar to those developed by ASTM, only that they’re specifically geared towards aerospace.

In addition, we have provided passivation to standards set forth by some of the biggest manufacturers and government agencies in existence, including:

  • Boeing
  • Lockheed Martin
  • Honeywell
  • Accutherm
  • Allied signal
  • NASA

EMI passivation services meet or exceed the most stringent requirements set forth by the industry. We can provide passivation services at the quality levels you need. Call us today to learn more.
