Calibration

MPA Universität Stuttgart is equipped with an excellent calibration laboratory which was accredited for the first time in 1995 by the Deutschen Kalibrierdienst and by the Deutschen Akkreditierungssystem Prüfwesen GmbH and presently by the Deutschen Akkreditierungsstelle GmbH (DAkkS). With more than 45,000 calibration certificates under the accreditation the MPA Universität Stuttgart has a lot of experience. The run time of the contracts  with our customers for more than 45 years is a signal of the high customer satisfaction. As an independent test body for calibration the MPA Universität Stuttgart offers the following services:

  • DAkkS calibration of force proving instruments in the range from 100 N to 1 MN. The calibration machines are traceable to the national standard of the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig
  • DAkkS calibration / verification of material testing machines including length measuring systems, hardness testing machines, impact testing machines
  • DAkkS calibration of the voltage range for amplifiers
  • DAkkS calibration of indenters for hardness measurements

Bearing and expansion joints in structural engineering

 The unit Bearing and Expansion Joints in Structural Engineering is an officially approved as well as notified inspection and certification body with testing, third party surveillance and certification (PÜZ) of bridge bearings, expansions joints and anti-seismic devices, as well as the investigation into qualification quality assurance and operational proving of bearings and components concerning bridges and constructions. Our objective is to improve the operating safety of constructional bearings by external controlling and quality assurance of components and constructions. Furthermore our aim is to improve development of bearings on the basis of research and the consequences from events of damage and in addition to qualify new materials and constructional concepts within the scope of research and development, the state of the art for contributing to standards and directives as well as minimizing the risk of damage. Our staff receives always training in order to meet all these high demands.

Emphasis is put on the following activities:

  • Research and approval tests to prove the applicability of materials and lubricants (components) of bridges and building constructions during short and long term tests in dependence on relevant loading parameters (such as pressure, temperature, velocity) as to friction, wear, creep
  • Acceptance tests on bearing components according to the required approval tests and standards as to materials characteristics (strength, hardness), surface characteristics, friction and wear behaviour
  • Third party surveillance and certification of bearing systems such as slide bearings, spherical bearings, pot bearings, roller bearings, restrained bearings and approval of components
  • Third party surveillance and certification of bridge expansion joints according European Technical Approval Guidelines (ETAGs)
  • Third party surveillance and certification of anti-seismic devices according EN 15129
  • Analysis of events of damage and assessment of the installation situation in the construction, investigation of dismantled bearings
  • Expert activities
  • Advice on processes in bearing technology
  • Cooperation in committees and the expert committee "bearings" of the Deutsches Institut für Bautechnik Berlin
  • Training of experts in bearings in structural engineering

Bearing Installation Course

 

Bearings for bridges and buildings are safety-relevant components. Bridge bearings need to be designed and produced therefore in Germany according to national technical approvals and national standards. For the reliability of the bearings in practice are in addition to a production corresponding to the regulations in particular the undamaged transport to the building structure and the professional installation of importance.
In the courses design and performance features of approved bearing types, essential content of valid regulations, understanding of their requirements, the concept of quality assurance and basic knowledge necessary for the proper transport and installation in the building structure in theory and practice are conveyed.
Depending on the type of course the in lectures mediated content is supplemented and deepened by practical exercises and experimental demonstrations.

  • Course A: The five-day bearing installation course with examination serves the acquisition of a temporary 5-year qualification for installation of bearings in bridge and building construction, the successful completion is confirmed by a certificate.
  • Course B: The two-day bearing installation course without examination serves the acquisition of knowledge of the installation and installation check for bearings in bridge and building construction.
  • Course C: The two-day refresher course is designed for the extension of the in Course A acquired qualification for another 5 years.
