ISO 15856:2009是空间环境模拟系列的第一部分，用于对空间使用的材料进行地面试验。本国际标准涵盖暴露于模拟空间辐射的非金属材料的测试。非金属材料包括玻璃、陶瓷和聚合物金属复合材料，如金属基复合材料和层压材料。ISO 15856:2009不包括用于电子元件的半导体材料。模拟辐射的类型包括带电粒子（电子和质子）、太阳紫外线辐射和太阳耀斑的软X辐射。辐射环境的协同作用仅适用于这些自然和某些诱发的环境效应。 ISO 15856:2009概述了模拟空间辐射对材料影响的推荐方法和实践。模拟方法用于再现空间辐射环境对位于航天器表面和屏蔽后面的材料的影响。

ISO 15856:2009 is the first part of a series on space environment simulation for on-ground tests of materials used in space. This International Standard covers the testing of non-metallic materials exposed to simulated space radiation. Non-metallic materials include glasses, ceramics and polymer-metal composite materials such as metal matrix composites and laminated materials. ISO 15856:2009 does not cover semiconductor materials used for electronic components. The types of simulated radiation include charged particles (electrons and protons), solar ultraviolet radiation and soft X-radiation of solar flares. Synergistic interactions of the radiation environment are covered only for these natural, and some induced, environmental effects. ISO 15856:2009 outlines the recommended methodology and practices for the simulation of space radiation effects on materials. Simulation methods are used to reproduce the effects of the space radiation environment on materials that are located on surfaces of space vehicles and behind shielding.
