20、the head of the cable tie when the force is applied in the manner specified. It shall be used together with EN 4057-100. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated refer-ences, only the edition cited applies. For undate
21、d references, the latest edition of the referenced document (including any amendments) applies. EN 4057-100, Aerospace series Cable ties for harnesses Test methods Part 100: General 3 Preparation of specimen Section the head of the cable tie along the plane as shown in Figure 2, taking care not to m
22、ove the locking device during this process. Precondition the cable tie as required in EN 4057-100. 4 Apparatus A tensile tester that will separate at a constant rate of 25 mm/min and 50 mm/min and apply sufficient force to pull out the locking device. A sample mounting fixture as in Figure 1, capabl
23、e of being fitted onto the tensile testing machine and suitable for the size of cable tie being tested. 5 Procedure Securely mount the cable tie head in bottom fixture as shown in Figure 1. Lock the top clamps onto the locking device and assemble into the tensile test machine ensuring that the lock-
24、ing device is aligned along the axis of pull. Separate the jaws of the tester at 25 mm/min and 50 mm/min and record the maximum force required to pull out the locking device from the cable tie head. 6 Requirements The force to pull the locking device out from the head of the cable tie, shall meet th
25、e requirements specified in the appropriate product standard.
