Level 3 – Enclosure Integrity Certification

Level 3 – Advanced Testing & Leakage Location

Level 3 is tailored for experienced technicians looking to expand their capabilities beyond single-fan testing. It focuses on larger, more complex enclosures and advanced techniques for locating and quantifying leakage paths.

Technicians will learn:

• Leakage distribution measurement using pressure neutralization with dual fans

• Techniques involving plastic membranes for leakage mapping

• Advanced testing procedures for attached volumes, extended discharge durations, and subfloors

This course also delves deeper into the theory behind the tests, enhancing the technician’s ability to interpret results and understand the physical phenomena being measured.

Expiration Policy: Completion is required within six months of enrollment. A recertification fee is necessary to continue or add new levels after expiration.
