This specification covers the general requirements for nonestablished reliability (non-ER) and established reliability (ER), multiturn lead-screw actuated, and single-turn, nonwirewound, variable resistors with a contact bearing uniformly over the surface of the entire resistive element, when positioned by an actuator. These resistors are capable of full-load operation (when the maximum resistance is engaged), at a maximum temperature of 150 Degrees C, with a resistance tolerance of å±10 percent. The ER resistors will have life failure rate levels ranging from 1.0 to 0.001 percent per 1,000 hours (see 1.2.1.5). These failure rate levels are established at a 60 percent confidence level maintained at 10 percent producer’s risk on the basis of the life tests.
