EN 3909:2007
(Main)Aerospace series - Test fluids and test methods for electric components and sub-assemblies
General Information
- Abstract
This standard specifies tests to demonstrate that components and sub-assemblies will not be adversely affected by contaminating fluids to which they may be exposed. The fluids listed are representative of those commonly used and encountered in airborne and ground operations, and align with the requirements of Section 11 – Fluids susceptibility of ISO 7137. Fluids not listed, and for which a test is required, should be included in the product standards.
These tests are not intended to demonstrate the suitability of components and sub-assemblies to perform in continuous contact with a fluid e.g. on an immersed fuel pump, nor are they tests to demonstrate immunity from electrolytic corrosion.
It shall be used together with TR 4542.
