中文名称；气密性检验

外文名称；air tight test

原理；利用内外气体的压力差检查泄漏

所属学科；机械工程
|}

将压缩空气(或氨、氟利昂、氦、卤素气体等)压入容器，利用容器内外气体的[[压力]]差检查有无泄漏的试验法。

'''气密性检验'''需用气密性检测仪，它是专门应用于对腔体[[机械]]产品进行密封性检测的装置。主要用于汽车发动机、变速箱、车桥、水箱、油箱等对容腔有密封要求的生产中。气密性检测仪采用嵌入式控制的智能化设计，可自动完成测试[[程序]]，并对检验结果进行自动判别。<ref>[https://jingyan.baidu.com/article/63acb44a2e3a7661fcc17e1b.html 化学:如何检查装置的气密性],百度经验 , 2018-06-07</ref>
