The Air Tightness Testing & Measurement Association (ATTMA) is a professional association dedicated to promoting technical excellence and commercial effectiveness in all air tightness testing applications. It was formed in 2002 to promote the testing and measurement industry and supports its members by extending market awareness of the technology and the members’ services.
In 2023, it launched the domestic ventilation commissioning scheme, allowing testers to commission domestic ventilation systems from intermittent systems to MVHR.
