Process management for avionics - Atmospheric radiation effects - Part 4: Design of high voltage aircraft electronics managing potential single event effects

IEC 62396-4:2013(E) provides guidance on atmospheric radiation effects and their management on high voltage (nominally above 200 V) avionics electronics used in aircraft operating at altitudes up to 60 000 ft (18,3 km). This part of IEC 62396 defines the effects of that environment on high voltage electronics and provides design considerations for the accommodation of those effects within avionics systems. This part of IEC 62396 provides technical data and methodology for aerospace equipment manufacturers and designers to standardise their approach to single event effects on high voltage avionics by providing guidance, leading to a standard methodology.
This publication is to be read in conjunction with IEC 62396-1:2012.

IEC TR 62396-8:2020(Main)
Process management for avionics - Atmospheric radiation effects - Part 8: Proton, electron, pion, muon, alpha-ray fluxes and single event effects in avionics electronic equipment - Awareness guidelines

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.

Process management for avionics - Electronic components capability in operation - Part 1: Temperature uprating

IEC TR 62240-1:2018 is available as IEC TR 62240-1:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC TR 62240-1:2018 is a technical report, which provides information when using semiconductor devices in wider temperature ranges than those specified by the device manufacturer. The uprating solutions described herein are considered exceptions, when no reasonable alternatives are available; otherwise devices are utilized within the manufacturers’ specifications. This document describes the methods and processes for implementing this special case of thermal uprating. All of the elements of these methods and processes employ existing, commonly used best engineering practices. No new or unique engineering knowledge is needed to follow these processes, only a rigorous application of the overall approach. The terms “uprating” and “thermal uprating” are being used increasingly in avionics industry discussions and meetings, and clear definitions are included in the present IEC Technical Report. They were coined as shorthand references to a special case of methods commonly used in selecting electronic components for circuit design. This new edition cancels and replaces the first edition published in 2013 and includes a revised wording for subclause 4.1 (Introduction to selection provisions) and the associated flowchart.
