FAQ
Frequently asked questions
What does accreditation mean?
Accreditation is formal confirmation by the Accreditation Body of Serbia (ATS) that the laboratory meets ISO/IEC 17025:2017 and is competent for the tests in its scope. Our accreditation number is 01-008.
What is in the scope of accreditation?
Thermo-technical testing of water and air installations, heat exchangers, air permeability of apartments and buildings, heat transmission and thermography, plus physical testing of the working environment, noise, sound insulation and reverberation time. The full list of methods and standards is in the table on this page.
When do I need a report from an accredited laboratory?
Typically for building handover and the occupancy permit, when the client or supervisor needs proof of workmanship, for inspections, and in disputes about construction quality or noise.
Since when is the laboratory accredited?
Initial accreditation: 3 September 2001. The current scope is valid from 28 July 2025 and the accreditation is valid until 15 March 2027.
Where do you work?
Our office and laboratory are in New Belgrade; testing takes place on site at your building. Locations outside Belgrade by arrangement.
