5 Test Methods
5.1 Unless otherwise specified in the specific test method, the test should be conducted after being stable for 2 hours under the following conditions: ambient temperature: 18 ℃~28 ℃, relative humidity of air: 45%~75%, atmospheric pressure: 86kPa~106kPa. 5.2 The size of the wire harness should be tested with a steel tape and should comply with the provisions of 4.2. &Nbsp 5.3 Visual inspection of the appearance of wire harnesses should comply with the provisions of 4.4.1, 4.4.3, 4.4.6.1, 4.5.2, 4.5.3, 4.5.5, 4.6, 4.7, 4.8, and 4.9.
5.4 The bending test of the insulation layer crimping part shall be carried out as shown in Figure 2. The process of bending 30 ° with the axis as the reference, then bending 60 ° in the opposite direction, and then returning to the axis is a cycle. 5.5 Wire to terminal connection, puncture connection, tension and tear force test of contacts shall be conducted using a tensile testing machine with a relative error of no more than 1%. The displacement of the clamp of the tensile testing machine shall move at a uniform speed, with a speed of 25mm/min to 100mm/min 5.5.1 Wire to terminal connection, puncture connection, and tension test of contacts. Apply tension along the wire axis direction. 5.5.2 Tear force test for solderless welded joints
