There are various kind of airtightness tester organizations. Some organizations are led by the qualification scheme in the country for example the British ATTMA and iATS and the Belgian BCCA. In France Qualibat is in charge of the qualification process with about 1000 qualified testers and Syneole is the trade union for airtightness testers. Among other things, Syneole represents airtightness testers in standardization and regulation working groups and is part of the commission for tester qualification.
In Germany the association FLIB, more than 300 members, helps to improve both the implementation of airtightness and the measurement protocol by editing guidelines and contributing in standardization committee (such as for ISO 9972’s national annex).
There are also smaller associations of testers, such as the Association Blower Door CZ (A.BD_CZ) in the Czech Republic, gathering 21 members in 2022, which represents about half of the testers operating in the country. Its objective is also to improve measurement practice by performing round-robin tests with its members.
Since September 2012, TightVent hosts an airtightness associations committee (TAAC) with representatives of national/local associations or groups including, Syneole, A.BD_CZ, FLiB, iATS and ATTMA.
