Validation of Operating Theatres

Protection Factor Measurement of Operating Rooms

The new guideline DIN 1946-4:2008 Room Air Technology – Part 4: ‘Room air conditioning equipment in buildings and rooms of public health sector’ describes a test procedure on determination of a protection factor in operating theatres considering the following:

  • inclusion of German standard VDI 2167, guideline SWKI 99-3 of Swiss assoziation of building services engineering engineers
  • simulation of inner and outer contaminations
  • simulation of flow bodies (OP-table, OP-lamp, dummies) and heat sources

Following equipment is required for performing according testing:

The advantage of the Aerosol Distribution and Dilution System ADD 536 is its ability to have a combined aerosol distribution and dilution. For performing these validation tests only an aerosol generator and a particle counter is needed additionally.
By means of the control and data acquisition software OPQWin it is possible to create detailed test protocols.
