Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method identical with IEC 62396-2:2012 "Avionics Process Management Atmospheric Radiation Part 2. Airline Guidelines for single-particle effects in empty electronic systems.

The documents of our country that are consistent with the corresponding international documents that are normative references in this standard are as follows.

2016, IDT)

This standard compared with IEC 62396-2:2012, mainly made the following editorial changes.

--- The standard name changed to "atmospheric radiation effects of avionics system single-particle effect test guide." this standard is proposed by China Aviation Industry Corporation.

This standard by the National Avionics Process Management Standardization Technical Committee (SAC/TC427) centralized.

This standard was drafted unit. China Aviation Institute of Integrated Technology, Beijing Shengtao Ping Experimental Engineering Technology Co., Ltd., China Aviation Industry First Aircraft Design and Research Institute.

Introduction

This standard avionics system designers, manufacturers of electronic equipment and electronic components and their users to determine the large avionics Gas neutron single particle effect sensitivity method is GB/T 34956-2017 supplement.

This standard provides guidance on the use of single-particle effects data, data sources, and types of accelerated radiation sources used. When no when obtaining single event data, consider using appropriate radiation sources to conduct experiments to obtain single event data for avionics.

This standard also specifies the method of converting data obtained by different radiation sources into a single-particle effect rate for avionics.

Atmospheric radiation affects avionics systems Single particle effect test guidelines

1 Scope

This standard gives a guide to test methods for measuring the sensitivities of single-particle neutron single-particle effects to microelectronic devices. Due to the radiation source used and test methods, so this standard also gives how to use the test data to assess the device and function board at cruising altitude by the atmosphere SEE rate caused by child.

This standard applies not only to the aviation industry, but also to other areas.
