The Air Tightness Testing & Measurement Association (ATTMA) is a not-for-profit company limited by guarantee, owned and operated by its members. It is also a MHCLG appointed operator of a “Competent Persons Scheme” for air-tightness testing and runs a Registered Testers Scheme for Sound Insulation Testing.
ATTMA is a professional association dedicated to promoting technical excellence and commercial effectiveness in all air tightness and sound insulation 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.
The ATTMA Competent Persons Scheme commences 1 January 2015 and provides a combined scheme covering all parts of the industry. It is open to all those previously registered with BINDT and nearly 200 testers from over 100 firms have so far indicated their interest in joining. Scheme membership will be updated during January 2015 as testers confirm their wish to be part of the scheme and a list of scheme members will appear here as soon as possible.
Prior to 2015 all members of ATTMA had to be accredited by 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)
