GB/T 16292-2010 Translated English of Chinese Standard. (GBT 16292-2010, GB/T16292-2010, GBT16292-2010): Test method for airborne particles in cleanroom (zone) of the pharmaceutical industry
https://www.chinesestandard.net, 2019 M02 2 - 17 pages
This Standard specifies the test method for airborne particle contamination. This Standard is applicable to the verification of airborne particle testing and environment in cleanroom and clean areas in the pharmaceutical industry, sterile rooms or local air purification areas (including clean bench). This Standard cannot be used to characterize physical, chemical, or reflective, or reproducible properties of airborne particles.
