The actuator shall be secured in a holding device and the breakaway %orque applied to the end closure and breech assemblies. 4.3.2 Initial lock security
18、 The actuator shall be tested for initial lock security by securing the actuator body in a holding device and manually pulling on the strap assembly to assure that the webbing cannot be extended or retracted. 4.3.3 Residual mametism.- The actuator shall be tested for excessive re- sidual magnetism
19、 in an area free of local magnetic effects, by placing the actuator six inches from and at the same height as the compass in a north-south horizontal position (breech end at south) with the compass set in an east-west heading as shown in Figure I. The actuator shall be moved slowly past the com- pa
