Sammlung von Bauteil relevanten Mikroorganismen. Unsere Datenbank enthält Pilze, Algen, Bakterien und Moose, die von befallenen Bauteilen isoliert und taxonomisch bestimmt wurden.
Measurement Survey of airborne germs of indoor air by filtration in comparison to outdoor air
Standards DIN ISO 16000-16, DIN ISO 16000-17, DIN ISO 16000-18, DIN ISO 16000-19, VDI 4300-10
Measurement object Indoor air in comparison to outdoor air


Technical data

Test volume For short-term measurement typically 50 L for each filter
Test duration Nine-fold measurement, approx. 30 min for each reading point
Processing Preparation of the measured rooms according to VDI 4300-10
Evaluation According to UBA guide, counting of germs growing after 3, 7 and 10 days


Special features

Culture media Use of microbiological culture media for mesophilic and xerotolerant fungi and airborne bacteria as a matter of routine
Flexibility Use of gelatine filters allows also the application of a dilution series, apart from direct cultivation – depending on the expected germ load of the investigated air

 

Further tests in context

  • long term measurement of air germs, impaction or filtration 
  • microbial analysis of materials (e.g. floor insulation)
