The requirements concerning airtightness of the building envelope were introduced into the national standard ČSN 73 0540-2 in 2002. Until now the proof of compliance has not been mandatory. The compliance should be checked by means of testing according to the ČSN EN ISO 9972 standard (introduced in 2016 and translated into the Czech language in 2017).
However, the ČSN 73 0540-2 standard only sets the requirements but gives no further information about the time of test and the building preparation or other guidance beyond the ČSN EN ISO 9972 standard.
