本规范涵盖了非建立可靠性（非ER）和建立可靠性（ER）、密封（见3.27）和非密封网络（见3.27.1）的一般要求。这些网络完全由固定的薄膜电阻器组成。它们主要用于空间是主要问题的表面安装应用。本规范涵盖的ER电阻器的寿命故障率（FR）范围为每1000小时1%至0.001%（见1.2.1.7）。ER FR至少为60- 基于寿命测试的置信度百分比。设计师应注意在脉冲应用中使用这些电阻器（见6.4.4）。

This specification covers the general requirements for nonestablished reliability (non-ER) and established reliability (ER), hermetically sealed (see 3.27) and nonhermetically sealed networks (see 3.27.1). These networks consist entirely of fixed, film resistors. They are primarily intended for use in surface mount applications where space is a major concern. ER resistors covered by this specification will have life failure rates (FR) ranging from 1 percent to 0.001 percent per 1,000 hours (see 1.2.1.7). The ER FR are established at a minimum 60-percent confidence level on the basis of life tests. Designers are CAUTIONED on using these resistors in pulse applications (see 6.4.4).
