Development of ISO 23875 Operator's Maintenance Manual and certificate of conformance documentation 

 Who should take this course? Anyone using ISO 23875 to design, retrofit, performance test, certify, or maintain an operator enclosure. The course is focused on the implementation of the testing, reporting, and maintenance manual requirements. It provides a template for each of these administrative areas designed to save time and speed up operator enclosure compliance certification as required under ISO 23875.

World-renown expert and scientist in particle mechanics, Dr. R. Vijayakumar, Ph.D.,  presents a six lecture series on particle mechanics for the non-scientist. In this series, he reviews basic particle mechanics found in everyday life. He then reviews how particles are classified, measured, and used to evaluate air filtration media efficiency. This unique lecture series in particle mechanics will bring to life aspects of particles that impact our daily lives and filter media testing.  

While Dr. Vijayakumar uses some math in his explanations, you do not have to be competent in math to fully grasp the concepts presented in this lecture series. Dr. Vijayakumar serves as the international project lead for ISO 29463 - High-efficiency filters and filter media for removing particles from air.

In-Person Workshops


 This two-day workshop was designed to educate attendees on the best practices for developing operator enclosures that protect operators' lung health. It is focused on the engineer control requirements, design requirements, and existing and proposed standards and regulatory requirements which drive operator enclosure health and safety. The workshop assumes that the attendee has a working knowledge of operator enclosures and a basic understanding of filtration, pressurization, and HVAC function. The workshop tuition includes the ACTW workbook, a fully illustrated guide through the material.
