16、enia, Spain, Sweden, Switzerland and the United Kingdom. EN 3475-501:20064 1 Scope This standard specifies a method of measuring the resistance to cut-through of an insulated conductor or jacket. This test is limited to cables smaller than code 140 (gauge size 6) and insulations with a thickness of

17、0,38 mm or less. It shall be used together with EN 3475-100. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (

18、including any amendments) applies. EN 3475-100, Aerospace series Cables, electrical, aircraft use Test methods Part 100: General. 3 Preparation of specimens The test specimen shall be a single 450 mm length of insulated cable. Remove sufficient insulation from one end of the specimen for connection

19、to the detection circuit. 4 Apparatus A tensile tester (or equivalent apparatus) shall operate in a compression mode and be equipped with a means to record the force necessary to drive the cutting edge through the insulation of a finished cable specimen. The cutting edge shall be positioned across t

20、he specimen at 90 to its longitudinal axis and shall have the dimensions shown in Figure 1. The tester shall also be equipped with a chamber that allows the test to be performed after stabilisation at elevated temperatures, and a low voltage detection circuit shall stop the tester when the edge cuts

21、 through the insulation and contacts the conductor. EN 3475-501:20065 Figure 1 Needle holder 5 Method Carry out the test at the temperature specified in the applicable product standard. At elevated temperatures the apparatus must be stabilised prior to each test which may require up to one hour (1 h

22、) depending upon chamber and specimen size. Move the cutting edge through the insulation at a constant rate of loading of (1 0,1) N/s at the specimen until contact with the conductor occurs. Move the specimen longitudinally a minimum of 25 mm and rotate it 90 between each test, keeping the direction

23、 of movement and rotation constant. Perform eight individual tests on the specimen. Record the force at cut-through for each test. 6 Requirements The arithmetic mean value of the eight measured cut-through results shall exceed the value given in the product standard.
