Guidelines for the qualification test for differential pressure measuring
instruments for the measurement of underpressures in rooms where firing
installations are set up
These guidelines were created by the ZIV (Guild of Master Chimney Sweeps) in
collaboration with differential pressure measuring instrument manufacturers, the
TÜV SÜD Industrie Service GmbH test centre, firing and heat technology, and
the DVGW (German Technical and Scientific Association for Gas and Water).
Areas of application and purpose:
Firing installations which are dependent on indoor air must not be set up in
rooms with air extraction equipment. However, insofar as no dangerous
underpressure can arise while the firing installations are in operation,
