BS 3475-411:2018 pdf download – Aerospace series – Cables, electrical, aircraft use – Test methods Part 411: Resistance to fluids This European Standard specifies two methods of determining the fluid resistance of a finished cable. Method 1: occasional contamination. Method 2: contamination test. It shall be used together with EN 3475-100 and EN 3909. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

Where large cables are being tested a single specimen may be divided into two (2) after fluid exposure if the resulting pieces are of sufficient length to allow the post tests to be correctly carried out. Strip approximately 25 mm of both ends of each...
