airtightness tests

Purpose of the work

Presentation of the newly created standard VDI 2083/19 (VDI is the Association of German Engineers) for airtightness tests of clean rooms.

Content of the contribution

It has been ten years since the publication of a draft proposal, and now, many hundred measurements without a binding standard for such a sensitive area later, the day has finally come. We have a standard dealing exclusively with the airtightness of clean rooms.

Purpose of the work

To guarantee the reliability of airtightness measurements.

Content of the contribution

In response to the questions of the three regional governments that had found quality deficiencies with regard to airtightness tests, the Belgian professional association has developed a control software and has organized the certification of airtightness testers.

When conducting airtightness tests of buildings, you must ensure that all building parts to be measured have air connection, so that the test object can be considered as one single zone. This also applies to large buildings like office buildings, schools, old people homes, indoor pools, etc. with several floors and rambling floor plans. Openings that are too small for a constant air flow from the leakages to the measuring device can prevent an even pressure distribution.
