Level 1 supplies the required information needed by witnessing authorities to properly verify an enclosure integrity test was done correctly using a detailed checklist and guide that virtually guarantees all significant factors are properly checked. Level 1 gives designers and consultants, the essential information needed to optimally design enclosures and clean agent systems.
Properly designed enclosures and clean agent systems will yield the longest hold time and lowest peak pressure while reducing exposure to risk created by smoke events. Enclosure Integrity Testers will learn the same details for verification and design that will ensure they properly understand the designer’s and the witnesses’ requirements.
Testers should pass Level 1 before they can take "Level 2 – Basic Enclosure Integrity Testing and Peak Pressure Analysis," which teaches how the actual door fan test equipment and software is properly used.
Any portion of training, levels 1-3, that is not completed within 6 months of the commencement date will expire. After that time, a recertification fee will be required to complete any unused training or add any further levels.
Level 2 is designed for testers who will learn about door fan test equipment, including basic theory and operation, and give them the foundation to run a single fan enclosure integrity test in accordance with NFPA 2001, ISO 14520, or EN 15004.
Technicians will become familiar with the Enclosure Integrity Test Form that provides the chronological direction for any test, along with the companion guide that explains exactly what is required to complete each step. Exercises will be given to practice in the use of Retrotec's FanTestic Integrity software, which does all of the calculations in compliance with current standards.
Technicians will also learn to predict descending interface and continual mixing retention times, as well as peak pressures based on enclosure leakage measurements made using a door fan air leakage test kit. Separate door fan test procedures are used to measure the installed pressure relief vent area and the enclosure leakage that will determine Clean Agent hold times.
This course includes training paths for both ISO and NFPA procedures.
Any portion of training, levels 1-3, that is not completed within 6 months of the commencement date will expire. After that time, a recertification fee will be required to complete any unused training or add any further levels.
Level 3 is designed for testers with experience performing single-fan Enclosure Integrity tests, and need to be able to perform larger and more complex tests that, to a large extent, involve techniques to determine the location of leakage paths.
Technicians will learn how to measure leakage distribution through pressure neutralization tests where two fans are used for leakage isolation. Techniques to measure distribution using plastic membranes will also be taught.
This course covers more of the theory behind the test concepts and gives technicians a deeper understanding of what they are measuring and why. Also, more advanced tests on attached volumes, extended discharge and subfloors are covered in detail.
Any portion of training, levels 1-3, that is not completed within 6 months of the commencement date will expire. After that time, a recertification fee will be required to complete any unused training or add any further levels.
Certification is rewarded with a formal certificate from Retrotec. Certification and support is valid for 3 years from the completion date. Recertification is available at any time during those three years to maintain current knowledge, compliance and testing confidence.
