Overview

IBExU Institut für Sicherheitstechnik GmbH, commonly known as IBExU, is a German engineering services company based in Freiberg, Saxony, that specialises in explosion protection. Its tradition reaches back to 1928, making it one of the longer-established names in the field. The company operates as a European Notified Body under Directive 2014/34/EU (the ATEX equipment directive, which replaced Directive 94/9/EC on 20 April 2016), an accredited testing laboratory and an accredited certification body for equipment, protective systems and components intended for use in potentially explosive atmospheres, as well as for safety, control and regulating devices used outside such atmospheres. Beyond its European role, IBExU is recognised internationally. It is an accepted ExTL (IECEx Test Laboratory) and ExCB (IECEx Certification Body) within the IECEx Certified Equipment System, covering the testing and certification of equipment, protective systems and components for use in explosive atmospheres. It is also recognised by the U.S. Coast Guard as an independent laboratory for the testing and certification of electrical equipment and components for use in explosive atmospheres. The company is certified to ISO 9001 and is an An-Institut (affiliated institute) of the Technische Universität Bergakademie Freiberg. IBExU's services are aimed at manufacturers, operators and importers who need to demonstrate compliance with explosion-protection regulations and standards. Its portfolio spans testing, certification, assessment and related engineering services in the field of explosion protection. Because it is both a European Notified Body and an IECEx-recognised body, it can serve clients seeking access to European and international markets. The company presents itself as a traditional yet modern service provider, combining a long history in explosion protection with current accreditation and recognition.

History

IBExU Institut für Sicherheitstechnik GmbH traces its tradition in explosion protection back to 1928. The company is based in Freiberg, Saxony, Germany, a town long associated with mining and technical education, and it operates as an An-Institut (affiliated institute) of the Technische Universität Bergakademie Freiberg. Over the decades it developed into an engineering services provider focused on explosion protection, combining testing, certification and assessment work. A significant regulatory milestone came with the European Union's ATEX framework. Directive 94/9/EC, the original ATEX equipment directive, was replaced by Directive 2014/34/EU on 20 April 2016. IBExU is a European Notified Body within the scope of Directive 2014/34/EU, accredited as a testing laboratory and certification body for equipment, protective systems and components intended for use in potentially explosive atmospheres, as well as for safety, control and regulating devices for use outside explosive atmospheres. Its accreditations apply to the testing procedures and areas named in the annexes to its accreditation certificates. Internationally, IBExU became recognised within the IECEx system as an accepted ExTL (IECEx Test Laboratory) and ExCB (IECEx Certification Body) under the Certified Equipment Scheme, covering testing and certification of equipment, protective systems and components for use in explosive atmospheres. It also gained recognition from the U.S. Coast Guard as an independent laboratory for testing and certifying electrical equipment and components for use in explosive atmospheres. The company is certified to ISO 9001. IBExU presents itself as a 'Traditionsunternehmen seit 1928' — a traditional company since 1928 — while maintaining current accreditations and international recognitions. Its official website provides further information about the company and career opportunities.
