Leakage-Test Pressure: Verify the Test Plan Before Pressurizing
Use only the pressure, duration, allowable leakage, equipment range, and sequence stated in the approved project test plan.
Stop if
- What approved test pressure and allowable leakage apply to this exact section, and who is authorizing the test?
Watch out
- Do not choose a pressure from memory, exceed the duct or equipment rating, or increase pressure to force a result.
Check
- Confirm the duct pressure class and section being tested
- Read the approved test procedure
- Verify gauge and fan range
- Confirm the allowable leakage basis and test duration
- Get authorization before increasing pressure
Steps
