There are 3.5 million businesses in Germany, but fewer than one per cent of these are engaged in research activities. This represents an extremely important group, because it is only through research that a business can make new discoveries, innovate and grow. Stifterverband awards the “Innovative through Research” seal to businesses that demonstrate a particular commitment to research and development.

Round-robin tests for noise protection testing bodies at MFPA Leipzig GmbH

Round-robin tests for noise protection testing bodies at MFPA Leipzig GmbH

The German Association of Materials Testing Institutions (VMPA) has been successfully organising comparative tests for noise protection testing bodies for years, and since 2013 these have had a new format as a 2-day measuring campaign with five test centres measuring in parallel. The tests are mandatory for VMPA-recognised noise protection testing bodies.

Since 2016, the comparative measurements for impact noise, airborne noise and installation noise have been conducted on the premises with technical support from MFPA Leipzig GmbH. The specialist evaluation is carried out jointly with the National Metrology Institute of Germany (Physikalisch-Technische Bundesanstalt, PTB) and the German Acoustical Society (DEGA).

If you would like to participate, please send an email to berlin@ vmpa.de. You can also find more information in the round-robin test database of the German Federal Institute for Materials Research and Testing (BAM), EPTIS: https://www.eptis.bam.de/eptis/WebSearch/view/144538

Ruling on thermal insulation composite systems – TICS tested, monitored and assessed

Ruling on thermal insulation composite systems – TICS tested, monitored and assessed

The building regulations of the German federal states also include rules for construction products, construction types and construction systems and stipulate the proofs of usability that must be provided. MFPA Leipzig GmbH prepares General Technical Test Certificates and assists you in obtaining General Technical Approvals and approvals on a case-by-case basis. The recent ruling by the Higher Regional Court of Stuttgart shows that it can be expensive to build without the proper documentation.

 

HAGER Rechtsanwälte PartG mbB attorney Mirko Zebisch writes: “In the course of the proceedings, it became apparent that the TICS which was placed in use had no General Technical Approval and also no approval on a case-by-case basis; in any case, the builder was unable to furnish any such proofs. The senate based its argument on the fact that, under the state building regulation of Baden-Württemberg, construction products may only be used for the erection of physical structures if the proof of usability is documented by means of a standard or, in the case of unregulated construction products, by means of a General Technical Approval, a General Technical Test Certificate or an approval on a case-by-case basis.”

The ICCRRR attracted more than 180 participants and featured 136 presentations (in two parallel sessions) on the subjects of concrete repair, rehabilitation and retrofitting. The IWCS consisted of 39 events focused on concrete spalling as a result of fire exposure and was attended by some 70 participants. Further details, including the full programme, are available at www.iccrrr.com.

BELFA – a Leipzig newcomer

BELFA – a Leipzig newcomer

The latest addition to our service portfolio is the “BELFA”. Short for “Belastungsfahrzeug”, the BELFA load-testing vehicle makes it possible to carry out load assessments for bridges on site at laboratory quality, using cutting-edge technology and experienced personnel. Load tests can be used to measure the load-bearing capacity of bridges exceptionally accurately – often providing figures that differ considerably from calculations. Decisions on demolition, reconstruction, maintenance and reinforcement can thus be made quickly on the basis of demonstrable evidence. Further information on the redesigned and updated BELFA is available at belfa.eu.

Load test for historic staircases

Load test for historic staircases

On 14 August 2015, inFranken.de reported on MFPA Leipzig’s recent work at the Luitpoldbad building in Bad Kissingen:

Robust and resistant

The stability of the historic staircases in the east and south wings of the Luitpoldbad building in Bad Kissingen has been put to the test. Top marks – the supports can withstand a load of 600 kg per square metre.

By THOMAS MÄUSER

400 kg... 500 kg... “This is where it gets exciting,” says Dr. Elke Reuschel. She checks the screen showing the data from the monitor – inching closer to 600 kg. This is the weight per square metre that the staircase of the former Luitpoldbad has to be able to withstand. Success! The historic staircases and their supports have passed the test.

Elke Reuschel is a division manager at the MFPA in Leipzig – the Leipzig Institute for Materials Research and Testing for the Construction Industry (“Gesellschaft für Materialforschung und Prüfanstalt für das Bauwesen”). As contracted by the state construction authority, the professor and her staff have been testing the stability of the staircases in the east and west wings of the building.

Metal support structures

During an assessment of the Luitpoldbad building in 2013, it was discovered that the two staircases concealed a set of exceptionally well-designed cast iron and steel supports. Once uncovered, they were deemed to offer high conservation potential, as long as they could still provide sufficient stability.

Neither of the staircases dates back to when the Luitpoldbad was originally constructed in 1868–1871; they were installed during renovation works in around 1906. “We tried to assess the design as accurately as we could, but it wasn’t possible to complete a conclusive analysis, as a number of uncertainties remained,” says structural engineer Martin Folchert. A load test had to be carried out to check stability in a definitive way. The contract was tendered and awarded to the MFPA in Leipzig, as Erwin Full from the state construction authority reports.

Cables and sensors

A load test in this context isn’t about piling on heavy weights or bags of cement. Instead, tensile forces are used. “We’re using hydraulics to pull on the triangular support arms,” explains Elke Reuschel. The traction cables are attached to these support arms. Metal supports are secured in the foundations to serve as counterweight for the duration of the test. MFPA staff have also attached highly accurate sensors to the balustrade’s supports. These sensors transfer information to the computer about any deformations caused by the heavy load. The measurements will be a matter of millimetres. 

When the staircases were originally built, they were expected to withstand 400 kg per square metre. These days the requirement is 500 kg – but the supports at the Luitpoldbad are also being tested for 600 kg.

One of Elke Reuschel’s colleagues pumps oil into the hydraulic column – the traction cables tighten, but nothing breaks or even makes a sound before the required load is reached. At the slightest hint of trouble, the test would be called to a halt immediately. “We always stop testing before any damage is caused,” says Elke Reuschel.

A real novelty

There aren’t many companies that carry out load tests of this kind. Even for staff at the state construction authority, this measurement task is something of a novelty. “I’ve been working here for nearly 40 years, but I’d never done anything like this before,” says Otto Gass, one of the state construction authority employees.

There is evidently a sense of relief among all of the state construction authority staff when it becomes clear that the historic staircases can remain in place without requiring extensive additional safety measures. Unfortunately, the handrails are missing – they must have disappeared at some point. However, catalogues are still available from earlier days. “These will be used as the basis for reconstructing the handrails just as they used to be,” says Erwin Full.
