Aerospace series - Test fluids and test methods for electric components and sub-assemblies

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.

Luft- und Raumfahrt - Prüfflüssigkeiten und Prüfverfahren für elektrische Bauelemente und Untergruppen

Diese Norm legt Prüfungen fest zum Nachweis, dass Bauelemente und Untergruppen durch kontaminierende Flüssigkeiten, denen sie ausgesetzt sein können, nicht nachteilig beeinflusst werden. Die aufgeführten Flüssigkeiten sind charakteristisch für üblicherweise bei Luft- und Bodenanwendungen verwendete und anzutreffende Flüssigkeiten und erfüllen die Anforderungen nach Abschnitt 11 - Empfindlichkeit von Flüssig¬keiten der Norm ISO 7137. Nicht aufgeführte Flüssigkeiten, für die eine Prüfung erforderlich ist, sollten in den Produktnormen enthalten sein.
Diese Prüfungen dienen weder dazu, einen Nachweis für die Eignung von Bauelementen und Untergruppen für den ständigen Kontakt mit einer Flüssigkeit, z. B. an einer Kraftstoff-Tauchpumpe zu erbringen, noch handelt es sich dabei um Prüfungen zum Nachweis der Beständigkeit gegen elektrolytische Korrosion.
Diese Norm ist gemeinsam mit TR 4542 anzuwenden.
