Scope
GB/T 46132-2025 is the English-translated version of 空间环境 航天材料空间辐射效应试验方法.
GB/T 46132-2025 is the Chinese national standard covering irradiating a material as orbit would — the electron, proton and ultraviolet exposures and the doses that stand for a mission, the vacuum kept throughout because bringing a specimen to air between steps changes the result, and the properties measured after. First edition, under the Chinese Academy of Sciences, and it belongs with the component test standards GB/T 46174 and 46189-2025. Already in force. Issued on 29 August 2025, it has been in force since 29 August 2025.

Space environment and space radiation effects of aerospace materials Test methods
1 Scope
This document describes the test methods for the effects of space radiation on aerospace materials.
This document applies to the single-factor environmental effects and multi-factor environmental synergy of aerospace materials in space radiation environments such as electrons, protons, and ultraviolet radiation.
Ground simulation test of the effect.

4 Experimental Purpose and Principle
4.1 Purpose of the Test
Obtain aerospace materials that can withstand performance changes in radiation environments such as electrons, protons, and ultraviolet rays.
4.2 Test Principle
Place aerospace materials in a ground simulation environment, and use ground simulation of electrons, protons, gamma rays, etc. according to the principle of equivalent effect simulation.
Dose depth distribution in the material (according to the requirements of Appendix C of GB/T 42846-2023) and dose depth of space energy particles in the material The distribution is equivalent, using a specific light source to simulate the radiation of ultraviolet radiation on the material in space, and the material is subjected to the test before, during or after the test.
It can conduct in-situ or ex-situ testing to obtain the changes in the performance of aerospace materials due to space radiation.
Taking the electron, proton and ultraviolet comprehensive irradiation simulation test as an example, the test device and irradiation simulation are shown in Figure 1.
