3. TECHNICAL REQUIREMENTS
3.1 Material Material requirements for cable, end fitting, and ferrule shall be as specified on the part standards. 3.2 Design 3.2.1 Finished safety cable shall conform to AS3509, AS3510, AS3511, or AS3655. 3.2.2 Corresponding finished safety cable ferrules shall conform to AS3509, AS3510, AS3511, AS3618, AS3619, or AS3655. 3.3 Construction 3.3.1 Wire Properties Tensile strength of wire and wire sizes shall be such that the cable will be capable of meeting the requirements of this specification. 3.3.1.1 Preforming of Wires The individual wires comprising a strand shall be shaped into the exact helical position they will have in the finished strand or cable, so that if the strand or cable is cut, the measured diameter of the cable at the cut ends shall not increase by more than 0.004 inch (0.10 mm) for nominal cable diameter 0.022 inch (0.56 mm), shall not increase by more than 0.006 inch (0.15 mm) for nominal cable diameter 0.032 inch (0.81 mm), shall not increase more than 0.008 inch (0.20 mm) for nominal cable diameter 0.040 inch (1.02 mm), and shall not increase by more than 0.009 inch (0.23 mm) for nominal cable diameter 0.062 inch (1.57 mm). 3.3.1.2 Splicing and Joining There shall be no wire splices in the finished strand or cable.3.3.2 Type of Construction 3.3.2.1 0.022 inch (0.56 mm) diameter safety cable shall be 1 x 7 construction. 3.3.2.1.1 Strand 1 x 7 The 0.022 inch (0.56 mm) nominal diameter cable shall be a strand of wires having 1 x 7 construction, consisting of a lay of six wires laid around a center core wire in a left-hand, or right hand direction. The length of lay shall be not more than 0.25 inch (6.35 mm) nor less than 0.20 inch (0.51 mm). 3.3.2.2 0.032 inch (0.81 mm) diameter safety cable shall be 3 x 7 construction. 3.3.2.2.1 Cable 3 x 7 The 0.032 inch (0.81 mm) nominal diameter cable shall consist of three strands of seven wires each, laid together without a core. Each strand shall consist of a layer of six wires laid around a center core wire in a left-hand direction. The three strands shall be laid together in a right-hand direction. The length of the lay of the six outer wires in each strand shall not exceed 70% of the lay of the finished cable. The length of lay of the finished cable shall be not more than 0.25 inch (6.35 mm) nor less than 0.18 inch (4.57 mm). 3.3.2.3 0.040 inch (1.02 mm) diameter safety cable shall be 7 x 7 construction. 3.3.2.3.1 Cable 7 x 7 The 0.040 inch (1.02 mm) nominal diameter cable shall consist of six outer strands of seven wires each laid around a core of seven wires. The six outer strands shall consist of six wires laid around a center wire in a left-hand direction. The core strand shall consist of six wires laid around a center wire in a right-hand direction. The six outer strands shall be laid around a core in a right-hand direction. The length of lay of the outside six wires in each of the six outside strands, and the outside six wires of the core strand shall not exceed 60% of the length of lay of the finished cable. The length of lay of the finished cable shall be not more than 0.37 inch (9.40 mm) not less than 0.24 inch (6.10 mm).
