The Air Tightness Testing & Measurement Association is a company limited by guarantee, owned and operated by its members. It is also a Department for Communities and Local Government (DCLG)-appointed operator of a “Competent Persons Scheme” for air-tightness testing.
The Air Tightness Testing and Measurement Association (ATTMA) is a professional association dedicated to promoting technical excellence and commercial effectiveness in all air tightness testing and air leakage measurement 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.
The ATTMA Scheme commenced 1 January 2015 and provides a combined scheme covering all parts of the industry. It is open to all those previously registered with British Institute of Non-Destructive Testing (BINDT) and nearly 200 testers from over 100 firms have so far indicated their interest in joining.
Prior to 2015 all members of ATTMA had to be accredited by United Kingdom Accreditation Service (UKAS) to ISO/IEC 17025, with a scope covering air tightness testing to ATTMA Technical Standard 1 and BS EN:13829 (2001). This third party accreditation demonstrates the technical competence of ATTMA members in carrying out air tightness testing, including calibration of the equipment used and training of staff carrying out the test. A test report carrying the ATTMA and UKAS logos will therefore be recognisable and technically credible. Members of ATTMA are BINDT Registered to test dwellings (L1A, Section 6 domestic and Technical Booklet F1) and new buildings other than dwellings (L2A & L2B, Section 6 non-domestic and Technical Booklet F2).
