随着科学技术经济贸易的迅猛发展,自然资源海洋宇宙开发与利用,各种产品在贮存、运输和使用过程中遇到的环境越来越复杂,越来越严酷。从热带到寒带,从平原到高原,从海洋到太空等等,这就使得用户和生产者双方都关心产品在上述环境中得性能、可靠性和安全性,以保证产品能满意地工作,这就必须要进行环境试验。

对产品的评价不能只看其功能和性能是否优秀,还要综合其各方面条件,例如在严酷环境中,其功能和性能的可靠程度以及维修、成本高低等。在提高产品可靠性方面,环境试验占有重要位置,说的极端一些,没有环境试验,就无法正确鉴别产品的品质、确保产品质量。

自然环境试验是将产品特别是材料和构件长期直接暴露于某一自然环境中,以确定该自然环境对它的影响过程,通常在各种类型的自然暴露场进行;

使用环境试验是将产品安装于载体(平台)上,直接经受产品使用中遇到的自然(或诱发)的平台环境的作用,以确定其对平台环境的适应性,通常在现场进行;

实验室环境试验则是将产品置于人工产生的气候、力学或电磁等环境中,以确定这些环境对它的影响,通常在实验室内进行。

气候环境试验其项目可分为如下几项:高温、低温、温度循环、温度冲击、低气压、湿热、日光辐射、砂尘、淋雨等,一般将盐雾和霉菌试验包括在其中。

从本世纪初,人们就注意到环境条件对产品的性能有很大的影响,随着产品越来越复杂和使用环境越来越严酷,环境试验受到人们的重视。

环境试验在国际上已有80多年的历史,1919年美国开始进行人工模拟环境试验,1943年,美国陆海空军便制定了环境试验方法。当时的试验项目主要是高温、湿热、低气压、砂尘、盐雾、日光辐射等,其主要的目的是解决热带沙漠地区作战的战斗机、装甲车等的质量问题。1955年,美国成立了环境工程学会。英国于1949年成立了环境工程学会。前苏联在五十年代就在国内各地建立了环境试验站,并在我国进行大量的暴露试验。东德于1962年成立了环境试验委员会,主要负责电信设备和元件方面的环境试验。

我国的环境试验始于五十年代,最先在广州、上海、海南岛等地建立了天然暴露试验站,与东欧各国共同探索热带、亚热带、沿海地区气候条件对产品的影响。我国的环境试验从学习国外的标准,到逐步建立自己的环境试验体系,几十年来有了很大的发展。目前,国内的环境试验工作正大面积地开展,各省市都建立了电子产品检验所(站),各大公司各大厂、所也都拥有自己的可靠性环境试验室,并陆续淘汰了旧设备,引进和购置了一些新设备,随着宇航事业的迅速发展,国防工业部门开始对可靠性和环境试验给予高度重视,并投入了巨大的人力、物力、财力,对提高军用产品的质量起到重要作用。

在环境试验中,人工模拟试验是最常用和最重要的试验方法,而环境试验设备是开展人工模拟试验工作研究的工具和手段。和环境试验一样,环境试验设备从本世纪二十年代至今已有80多年的历史了,从70年代开始,环境试验设备有了迅速发展,并逐渐成为一门综合性强技术复杂的边缘科学。

1) 国外气候试验设备的发展情况来看,大致可分为三个阶段:

环境试验设备设计、生产的依据是环境试验方法,随着生产力的进步、国民经济的发展,环境试验方法的日臻丰富,相应的环境试验设备亦随之日益增多。为了使环境试验能可靠、持续地得到实施,这就需要有质量上乘,性能合格的试验设备,而要达到这一要求,就需有一个统一衡量试验设备尺度即环境试验设备标准,以及环境试验设备基本参数检定标准。
