Level 2 – Enclosure Integrity Certification

Level 2 – Basic Testing & Peak Pressure Analysis

Level 2 is intended for testers ready to work hands-on with door fan equipment. It covers the fundamental theory and practical operation required to conduct single-fan enclosure integrity tests in compliance with NFPA 2001, ISO 14520, or EN 15004 standards.

Technicians will:

• Become familiar with the Enclosure Integrity Test Form and its step-by-step process

• Use the accompanying guide to understand each phase of testing

• Complete exercises using Retrotec’s FanTestic Integrity software, which automates calculations to meet global compliance standards

Additionally, testers will learn to:

• Predict descending interface and continuous mixing retention times

• Estimate peak pressure based on measured leakage

• Conduct separate tests to determine installed pressure relief vent areas and enclosure leakage

This course includes training for both ISO and NFPA protocol paths.

Expiration Policy: As with all levels, training must be completed within six months of the start date. A recertification fee applies to resume expired or incomplete training.
