Current industry filter leak scan testing standards and recommended practices require a minimum of 10 micrograms per liter (ug/l) as an upstream aerosol challenge concentration when using photometry as the primary detection method. While higher concentrations may be used, 10-ug/l is the minimum required concentration that must be used to maintain compliance. ATI aerosol photometers are designed to operate in accordance with all current industry standards and recommended practices.
