23、 on or off the aircraft, with two or more end destinations 3.2 cable bundle any group of cables which are tied together 1) Published by: DoD National (US) Mil. Department of Defense. http:/www.defenselink.mil/ BS EN 4056-001:2015EN 4056-001:2015 (E) 5 4 Conditions of use 4.1 Temperature ratings (typ

24、e) The ties shall be capable of use within the temperature range specified in the product standards. Temperature ratings shall be defined by the material codes specified in EN 4056-002. 4.2 Flammability class Ties shall meet either class 1 or class 2 flammability requirements as defined Table 2 test

25、 EN 4057-302 and in the appropriate product standard: Class 1 has the highest degree of flame retardant properties; Class 2 has a lower degree of flame retardant properties. 5 Descriptions and design 5.1 Description Ties, see Figure 1, shall be designed for installation by a tool providing controlle

26、d tension in accordance with MS 90387. The head design, locking system and strap cross sectional dimensions shall be such that the requirements of the tests given in Clause 6 are met. Ties are available with plastic or metallic locking mechanisms and those with plastic locking mechanisms may have ei

27、ther internal or external serrations on the strap. Figure 1 BS EN 4056-001:2015EN 4056-001:2015 (E) 6 5.2 Design and manufacture The finish shall prevent abrasion to the harness and to adjacent harnesses or breakouts. In completing the joint, no sharp or abrasive edges shall be formed that could dam

28、age the cable insulation of the loom or any adjacent looms, or that could cause injury to an operator. 5.3 Materials Ties shall be made from virgin materials which may be formulated to be UV resistant. The use of in process reground material to a maximum of 25 % by mass is permissible but is limited

29、 to the percentage used in the qualification sample.
