ISO 9022-6:2015规定了与光学仪器（包括其他领域（如机械、化学和电子设备）在同等条件下的环境试验相关的方法，以确定其抵抗扬尘影响的能力。 测试的目的是调查吹灰对试样的光学、气候、机械、化学和电气（包括静电）性能特性的影响程度，尤其是考虑到运动部件（如滑动面、轴承、触点、操作控制装置、齿轮）的故障或表面的不可接受磨损。 本试验的目的不是测定粗粉尘的耐磨性。

ISO 9022-6:2015 specifies the methods relating to the environmental tests of optical instruments including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices), under equivalent conditions, for their ability to resist the influence of blowing dust. The purpose of testing is to investigate to what extent the optical, climatic, mechanical, chemical, and electrical (including electrostatic) performance characteristics of the specimen are affected by blowing dust, especially with a view to malfunctions of moving parts (such as sliding surfaces, bearings, contacts, operating controls, gears) or unacceptable wear of surfaces. This test is not intended to determine the wear resistance to coarse dust.
