The Accreditation Body of Serbia (ATS) has expanded the scope of the TMS certification body to the area of conformity assessment of pressure equipment (PE), as well as simple pressure vessels. In the previous period, TMS gathered a team of top experts in this field, including Dejan Simonović, Milutin Nikolić and Mirko Đapić, and intends to provide services with the recognized quality in this extremely demanding area. In every country, pressure equipment is of great importance both for the safety of users and for the smooth operation of technical facilities and the economy in general.
