本规范涵盖了绝缘薄膜固定电阻器的未建立可靠性（非ER）和已建立可靠性（ER）的一般要求。这些电阻器能够在70摄氏度的环境温度下满负荷运行，并且具有百万分之100（PPM）和每摄氏度350（PPM/摄氏度）的电阻温度特性。ER电阻器的寿命故障率（FR）水平为每1000小时1.0%至0.001%（见1.2.1.4）。这些FR水平是在寿命测试的基础上以60%的置信水平确定的。设计师应注意在高功率脉冲应用中使用这些电阻器（见6.13.2）。

This specification covers the general requirements for nonestablished reliability (non-ER) and established reliability (ER), insulated, film, fixed resistors. These resistors are capable of full load operation at an ambient temperature of 70 Degrees C and have a resistance temperature characteristic of 100 parts per million (PPM) and 350 PPM per degree Celsius (PPM/ Degrees C). The ER resistors have life failure rate (FR) levels ranging from 1.0 percent to 0.001 percent per 1,000 hours (see 1.2.1.4). These FR levels are established at a 60 percent confidence level on the basis of life tests. Designers are CAUTIONED on using these resistors in high power pulse applications (see 6.13.2).
