本规范涵盖了既定可靠性（ER）和非既定可靠性（非ER）（产品等级C）、通用陶瓷电介质、绝缘固定电容器的一般要求，这些电容器用于电容在温度、电压、频率和寿命方面可容许明显变化的应用（见6.1）。本规范涵盖的ER电容器的故障率水平（FRL）（M、P、R和S）范围为每1000小时1.0%至0.001%。这些FRL建立在90- %置信水平，并保持在10%的生产商风险下，并且基于在最大额定电压和最大额定温度下进行的寿命测试。使用8:1的加速系数将在最高额定温度下200%额定电压下获得的寿命试验数据与额定温度下的额定电压联系起来。

This specification covers the general requirements for established reliability (ER) and non-established reliability (non-ER), (product level C), general purpose, ceramic dielectric, insulated, fixed capacitors for use in applications where appreciable variations in capacitance with respect to temperature, voltage, frequency, and life can be tolerated (see 6.1). ER capacitors covered by this specification have failure rate levels (FRL) (M, P, R, and S) ranging from 1.0 percent to 0.001 percent per 1,000 hours. These FRLs are established at a 90-percent confidence level and maintained at a 10-percent producer's risk and are based on life tests performed at maximum rated voltage at maximum rated temperature. An acceleration factor of 8:1 has been used to relate life test data obtained at 200 percent of rated voltage at maximum rated temperature, to rated voltage at rated temperature.
