本规范涵盖了精密、非线绕、可变电阻器的一般要求，其电气输出（以施加电压的百分比表示）相对于操作轴的角度位置为线性或非线性。本规范包括线性和非线性、单匝和多匝、单段（杯）和多段可变电阻器的要求。这些电阻器的电阻公差为±10%。这些电阻器能够在70OC的最高环境温度下满负荷运行，并且能够在适当降额时连续运行至125OC的最高温度（参见3.1、6.2和图10）。本规范包括一类、二类和三类精密电阻器的采购程序和要求。

This specification covers the general requirements for precision, nonwirewound, variable resistors whose electrical output (in terms of percent of applied voltage) are linear or nonlinear with respect to the angular position of the operating shaft. This specification includes requirements for linear and nonlinear, single turn and multiturn, single-section (cup) and multi-section variable resistors. These resistors have a resistance tolerance of å±10 percent. These resistors are capable of full-load operation at maximum ambient temperatures of 70OC and are capable for continuous operation, when properly derated, to maximum temperatures of 125OC, (see 3.1, 6.2, and figure 10). This specification includes procedures and requirements for the acquisition of category I, category II, and category III precision resistors.
