IBExU Inst. Für Sicherheitstechnik GmbH

What IBExU Inst. Für Sicherheitstechnik GmbH does

IBExU Institut für Sicherheitstechnik GmbH is a German engineering services firm headquartered in Freiberg, Saxony, specializing in explosion protection testing and certification. Founded in 1928 as the Saxon testing station by Prof. Karl Kegel and re-established as a GmbH in 1990, the company operates accredited laboratories and test facilities for determining the safety characteristics of combustible substances (dusts, gases, liquids and their vapors, mists/aerosols, and hybrid mixtures), and issues conformity assessments, expert opinions, and certifications under the ATEX Directive 2014/34/EU, the IECEx Certified Equipment Scheme, and U.S. Coast Guard recognition. It also conducts explosives accessories testing as a specialist facility recognized by the Saxon Oberbergamt and performs experimental investigations including MIL (MIL-STD-810), RTCA (DO-160), and IP degree-of-protection testing.

The firm's core revenue streams are professional-service fees from testing and certification engagements, paid seminars and in-house training on explosion protection (offered both in-person in Freiberg and online), and technical publications such as the 4th-edition reference book on safety characteristics of flammable gases and vapors. Distribution is direct-application: equipment manufacturers and industrial operators engage IBExU via quote-based per-application pricing, with 30-day invoice payment terms and reserved advance-payment rights. Marketing is primarily through the corporate website (ibexu.de / ibexu.com), email seminar newsletter, SEO/organic search, and in-person seminars with practical demonstrations.

IBExU is an An-Institut of TU Bergakademie Freiberg (since 1995), holds DAkkS accreditation as both testing laboratory (ISO/IEC 17025) and certification body (ISO/IEC 17065), and operates as European Notified Body 0637 under the ATEX Directive. It wholly owns IBExU UK Ltd., a UK approved body accredited by UKAS since 2022, providing post-Brexit UK market access. The firm exited its Marine Equipment Directive (RL 2014/90/EU) notified-body activities in 2023 and took over Autogentechnik (gas welding technology) testing from BAM on 31.12.2024. With approximately 9 employees and managing director Dr.-Ing. Dirk Bauersfeld, the firm operates as a tightly focused, privately held specialist in a regulatory-monopoly niche.
