13、. 4.5 Property and Performance Requirements All assemblies furnished to this specification shall meet the provisions and requirements of TMS-7006, and, in addition, the following requirements: 4.5.1 Sag Resistance 4.5.1.1 Method Extend coiled assembly to the maximum recommended working length (as sp
14、ecified on the part drawing) in a horizontal position by clamping at ends and hold for 16 hours at 24 3C (75 5F). While in the extended position, measure the deflection from a horizontal line at top of the coil at the assembly mid-point. Reduce the extension of the assembly to 50% of the recommended
15、 working length and hold. After 30 minutes, repeat the sag measurement. 4.5.1.2 Required Sag from the horizontal shall not exceed 4% of the maximum working length for full extension nor more than 8% of maximum working length for 50% extension. 4.5.2 Force of Extension 4.5.2.1 Method Extend coiled as
16、sembly to the maximum recommended working length at 24 3C (75 5F). Using a spring scale or other suitable measurement device, determine total force of extension. 4.5.2.2 Required Force to extend to maximum working length shall not exceed 66.7 N (15 lbf). 4.5.3 Ovality - Nylon Tubing 4.5.3.1 Method:
17、ASTM D 2122, Section #7, Calculations M in im u m O .D.a x im u m O .D. x 1 0 0 4.5.3.2 Required: Shall be a minimum of 75% ovality. 4.5.4 Restriction 4.5.4.1 Method: Measure the inside diameter of the metallic sleeve (sleeve inside tubing). 4.5.4.2 Required: A 12.7 mm (1/2 in) O.D. coiled assembly
18、shall have a minimum sleeve I.D. of 8.0 mm (0.315 in). 4.5.5 Fitting Tensile 4.5.5.1 Method: ASTM D 622 4.5.5.2 Required: Minimum pull-off shall be 1.45 kN (325 lbf) 4.5.6 Spring Guard Tensile 4.5.6.1 Method: ASTM A 318, Section 3, with cross head speed of 2.5 cm (1 in) per minute.
