There is a requirement in all clean air and containment industries to test the HEPA filter systems that protect people, product and environment. ISO14644-3 describes the installed filter leakage test, commonly referred to as the DOP (Dispersed Oil Particle) test. Being the preferred method in all industries expect microelectronics this test is global, and whilst it appears simple in fact it can be quite complex. Our Academy for Cleanroom Testing delivers a one-day course on testing installed HEPA filters, using trainers who are very experienced in this industry, the most current equipment and the latest best practices. The morning of theory will equip the delegate with great knowledge on what to test, what to test it with, when to test it, and how to test it. The afternoon is practical and gives the delegate confidence to set up the test equipment, connect to an installed HEPA filter system, carry out a test, and detect the leaks that we have created in test filters. Attendance is advised for anyone in the clean air and containment industries who has a role in Engineering, testing, Quality, cleanroom validation, Operations, management, inspections, or anyone responsible for the performance of clean air facilities and equipment. The course runs for 6-10 delegates, and a Manual and Certificate of Attendance is provided.
