After inquiries and votes carried out in accordance with the rules of ASD-STAN defined in ASD-STANs General Process Manual, this standard has received approval for Publication. prEN 6059-402:2017 (E) 3 1 Scope This standard specifies a method to determine the bending pr

12、operties of protection sleeve for electrical cable and cable bundles. It shall be used together with EN 6059-100. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the

13、 edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 6059-100, Aerospace series Electrical cables, installation Protection sleeves Test methods Part 100: General 3 Preparation of specimens A specimen with a minimum lengt

14、h of 600 mm is taken from a finished sleeve. prEN 6059-402:2017 (E) 4 4 Apparatus A spiral wrapped bending spring which has the nominal inner diameter of the specimen to be tested and capable of bending with a minimum radius (radius is specified as five times the nominal inner diameter, measured to

15、the centerline of the spring) as specified in the product standard. The sleeve shall be applied between two mandrels to bend the sleeve to both sides at the minimum specified bend radius. The sleeve shall be bent by means of a lever with a rotation point just above the mandrels, see Figure 1. The ap

16、plied mass shall be in accordance with the product standard. A counter to measure the cycles with an interface between lever and counter.

17、Figure 1 Test set-up for bending properties of sleeves prEN 6059-402:2017 (E) 5 5 Method The specimen should be bent 90 to left and 90 to right. The sleeve shall be applied between the two mandrels according to Figure 1. The number of cycles is specified in the product standard. The movement bent 90

18、 to left and 90 to right is one cycle. The axis of rotation for flex arm shall be at the same level or above the axis mandrels. Guide rods and weight loaded on conductors can be used so as to avoid movement not relevant for this test. For bundles whose diameter is larger than 32 mm, the use of convo

19、luted conduit to reduce the weight of harness during the test cables shall be used so as to prevent contact between the convoluted conduit and the sleeve. See Figure 2. Key A Protection sleeve B Cables arranged around conduit C Convoluted conduit Figure 2 Cable bundle with convoluted tube 6 Requirements The specimen shall be capable of bending to the minimum bend radius as specified in the product standard. Closing mechanisms (if present) shall not be opened or damaged. No damage or broken yams/strand shall be found after the test.
