The DOP may need to be increased or decreased. Downstream penetration of aerosol will then be measured using a photometer, scanning the filter face with overlapping strokes at a speed no greater than 5cm/s. The ISO 14644 Part 3 standard permits a maximum downstream limit of 0.01% penetration.

- What is DOP test?
- The DOP test, also known as the DOP aerosol test, is a standardized procedure used to evaluate the performance of high-efficiency particulate air (HEPA) filters.
- What is dispersed oil particulate (DOP) testing?
- Dispersed Oil Particulate (DOP) testing, also known as 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 challenged by introducing particulates and measuring the output. Keep the instrument in the area.
- What is a DOP machine?
- A machine used to move HEPA filtered air into or out of a construction site. DOP or dioctyl phthalate is an organic compound used as a poly-dispersed test aerosol, to generate sub-micron particles, to challenge (evaluate integrity of) of HEPA filters.
- What is a dioctyl phthalate (DOP) test?
- The test involves generating aerosol particles of a known size and concentration, typically using dioctyl phthalate (DOP), and passing them through the filter under controlled conditions. The objective of the DOP test is to determine the filter's efficiency at capturing particles of a specific size, typically 0.3 microns.
- Who makes aerosol testing equipment?
- Currently, the only known acceptable testing equipment is manufactured by ATI (Air Techniques International) and TEC Services Inc (TEC). ATI and TEC manufactures acceptable and widely used aerosol generators and photometers. Please refer to ATI’s website, www.atitest.com and TEC’s website, www.tecservicesinc.com for additional information.
