energy storage device air tightness test standard
Building Airtightness Targets and Standards
Codes and standards typically specify airtightness performance targets using either of two metrics: Air Changes per Hour (ACH) or Normalized Air Leakage Rate (in L/S per m2 of building enclosure area). Both metrics are reported at a specific pressure difference, usually 50 or 75 Pascals (Pa). The below table summarizes maximum air leakage rates ...

Launch a Pulse test. A Pulse test is initiated using the touch-screen control unit. This will release one or more "pulses" of air into the internal space of the building creating a pressure difference between inside and outside. Compressed air will be released to pressurise the building to 4Pa. As the increased pressure finds all the air ...

The accuracy of measurement should be ±1 m/s in the range 3 to 6 m/s. This is a nominal accuracy since the recommendation is to. ndertake air leakage measurements at wind velocities less than 6 m/s. Wind speed indicators tend to have poor accuracy at these low velocities and in any case accuracy.
