goals of A.BD.CZ Jiří Novák | April 2011 supervision and quality control of the professional activities of the members support of knowledge exchange and lifelong learning of the members development of measuring procedures and their implementation cooperation with state authorities

members of A.BD.CZ Jiří Novák | April members 19 mesuring devices membership open to every active airtightness test provider observation of ethical code required violations of ethical code – disciplinary procedure

ongoing activities Jiří Novák | April 2011 general meetings with workshops round-robin tests (2010, 2012) collection of test results development and analysis of a leakage database

planned activities Jiří Novák | April 2011 certification of members commentary of EN (common interpretation)

EU network - motivation / expectations Jiří Novák | April 2011 motivation −need of information exchange (learning from good examples, successful approaches...) −contribute, support this information exchange

EU network - motivation / expectations Jiří Novák | April 2011 motivation −need of information exchange (learning from good examples, successful approaches...) −contribute, support this information exchange expectations (role of the EU network) −gathering the information about the approaches adopted in different countries to deal with selected issues („summary tables“) −gathering detailed information concerning main issues (conference / workshop papers, leakage data...) −facilitate a homogenous testing practice - common approaches or guidelines (e.g. structure of test protocol, of a lekage database training...,)

we can offer... Jiří Novák | April 2011 experience with: −round-robin tests −development and analysis of a leakage database −implementation of EN −developpment of a common test protocol

thank you...
