Sample Volume
According to ISO 14644-1:2015 cleanroom classification standard, Required Single Sample Volume (VS) is the only formula (Formula A.2) that you should calculate as;
Vs=(20/Cn)*1000
Where, Cn is the class limit for the largest considered particle size.
If you print the below table out, you don’t have to calculate every single cleanroom ISO class and designated particle sizes. This table could prove to be useful for cleanroom qualification and contamination control departments!
