标准摘要
[中文适用范围]: 本部分国际电工标准旨在提供关于大气中微小粒子(即质子、电子、π介子和μ子通量)以及航空电子设备中单粒子效应的认识和指导。这适用于运行高度达 60,000 英尺(18,300 米)的航空器中使用的航空电子设备。这是一个新兴主题,缺乏实质性的支持数据。本文件旨在通过为此新兴主题提供认识指导,帮助航空航天或地面电子设备制造商和设计师。提供了辐射环境的详细信息以及由此导致的潜在问题识别。给出了量化电子元件中单粒子效应(SEE)率的适当方法。注 1:总体系统安全方法论通常扩展以适应单粒子效应率,并证明电子元件、电子设备和系统级电子设备的适用性。注 2:在本文件中,“电子器件”和“电子元件”一词可互换使用。虽然本文件是专门为航空业开发的,但其他工业部门可根据需要自行使用。 [外文原描述]: IEC 62396-8:2020 is intended to provide awareness and guidance with regard to the effects of small particles (that is, protons, electrons, pions and muon fluxes) and single event effects on avionics electronics used in aircraft operating at altitudes up to 60 000 feet (18 300 m). This is an emerging topic and lacks substantive supporting data. This document is intended to help aerospace or ground level electronic equipment manufacturers and designers by providing awareness guidance for this new emerging topic. Details of the radiation environment are provided together with identification of potential problems caused as a result of the atmospheric radiation received. Appropriate methods are given for quantifying single event effect (SEE) rates in electronic components.
