The ISO 9972 offers 3 methods for building preparation. The corresponding checklists
are stored in the Wöhler BC 600 app.
5.2.1 Method 1: Testing a
building in in use
All natural ventilation openings as well as open-
ings for mechanical ventilation or air conditioning
openings must be closed throughout the whole
building.
5.2.2 Method 2: Testing the
building envelope
All intentional openings must be sealed and all
doors, windows and trapdoors closed.
5.2.3 Method 3: Testing the
building for a specific
purpose
All intentional openings must be adapted to the
purpose of the measurement in accordance with
the corresponding applicable standards or guide-
lines of the respective country.
NOTE!
If it is not possible to seal openings with a sealing bladder, then they must be sealed
with the panel and duct tape or similar material.
