The degradation categories (N-, R-, and P-series) will be determined by using either sodium chloride (NaCl) or dioctyl phthalate (DOP) as the test aerosol. NaCl is only slightly degrading to filter efficiency, whereas DOP is very degrading.

What is DOP (Dispersed Oil Particulate) testing?

DOP, or filter integrity, testing is the process in which the integrity of your HEPA (High Efficiency Particulate Air) or ULPA (Ultra Low Penetration Air) filter is tested through the introduction of particulates. Find out more by exploring our Knowledge Centre.

Polyvinyl chloride

Since that time, studies of PVC workers in Australia, Italy, Germany, and the UK have all associated certain types of occupational cancers with exposure to vinyl chloride, and it has become accepted that VCM is a carcinogen. Technology for removal of VCM from products has become stringent, commensurate with the associated regulations.

Integrity testing of HEPA filters: A practical approach

Manufacturers of high-efficiency particulate air (HEPA) filters for cleanrooms and controlled environments test their products for particle removal efficiency. Equally, once the unit is installed in the user's production site, the test should be performed promptly to verify the integrity of the filter as well as the installation.

Respirator assigned protection factors

The respiratory protective devices (RPD) can protect workers only if their protective properties are adequate to the conditions in the workplace.Therefore, specialists have developed criteria for the selection of proper, adequate respirators, including the Assigned Protection Factors (APF) - the decrease of the concentration of harmful substances in the inhaled air, which (is expected) to be ...
