The test institute in Lathen

The testing in Lathen started in 2010 with the launch of the furnace for vertical test specimens as a branch of the accredited and notified testing centre for fire protection in Dortmund. In the following years, the test laboratory in Lathen was continuously expanded and currently has three vertical furnaces with a clear opening of up to 6.40 m x 5.3 m, a smoke test stand with a clear opening of 5.00 m x 5.00 m, a separate hall for durability tests and a sound-absorption test stand on a hall area of 2500 m².

A smoke control system specially built for fire tests ensures safe, environmentally conscious and climate-friendly decontamination of the combustion gases. The environmental management system of DMT GmbH & Co. KG is certified according to DIN EN ISO 14001:2015

These test reports are used as a basis for the allgemeinen bauaufsichtlichen Zulassung (general type approval) (abZ) at Deutsches Institut für Bautechnik, Berlin and at VKF in Switzerland. Furthermore they are used in the European procedure according to the Building Products Regulation in accordance with the product standard DIN EN 16034 as a proof for the creation of classification reports according to EN 13501-2 as well as reports for the extended application (EXAP reports) and in addiation, serve as proof of usability all over Europe.

The DMT Testing Institute for Fire Protection is horizontally notified for tests according to the procedures EN 1366-7, EN 1634-1, EN 1634-3, EN 1364-1, EN 1364-3 and EN 1364-4 of the Construction Products Regulation. This means that tests according to these procedures can be used for bringing construction products onto the market according to harmonised technical specifications under the Construction Products Regulation (EU Construction Products Regulation, EU 305/2011 "CPR") with the CE marking.


Gladly we support you with our expertise to achieve all necessary approvals.

Smoke control

Smoke control test chamber – 5,0 m x 5,0 m

In the smoke control test chamber, maximum dimensions of up to 5.00 m x 5.00 m or 3.40 m x 3.40 m can be tested for smoke protection. All other dimensions can also be realized after on request. The test equipment was developed in 2011 according to the state of the art technical standards. The control of the test stand is fully automatized.

For the smoke control test chamber, 14 mobile exchangeable test frames are available for mounting the test specimens. These allow a very flexible test process, so that the waiting times between assembly or possible improvements to the test specimen and the tests are minimized.


  • Test according to EN 1634-3, Smoke control test for door and shutter assemblies (Doors, Gates, Shutter assemblies, Windows) to determine the leakage rate

    Fire resistance and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware - Part 3: Smoke control test for door and shutter assemblies EN 1634-3

    This part of EN 1634 specifies a test method for determining the leakage of cold and hot smoke from one side of a closure to the other under given test conditions. The test may be applied to different types of closure designed to inhibit the circulation of smoke in the case of fire. This test method can also be applied to lift landing doors and railway conveyor closures.
  • Tests according to DIN 18095, tests for smoke control of smoke control closures (Doors, Gates, Flaps, Windows) to determine the leakage rate

    Testing of smoke control doors - Type testing of durability and tightness according to DIN 18095-2

    This standard specifies the test method to be applied for the verification of suitability of smoke control doors according to DIN 18095 Part 1 for durability and for tightness at ambient and increased temperaturer.

    The purpose of testing the smoke control behaviour of smoke control closures or fire protection closures is to determine leakage rates.

Durability

The separate and video-monitored durability test hall has an area of 200 m² and provides space for 10 test specimens to be tested in simultaneously.

The test specimens are mounted in mobile changeable frames with an opening clearance of up to 5.0 m x 5.0 m.

Furthermore, test stations for gates and conveyor systems and their closures (conveyor system closures) are available up to the maximum dimensions of (W x H) 25.00 m x 4.50 m or 20.00 m x 6.00 m.

The purpose of the standard tests is to prove the durability of the self-closure (long-term functional tests). For this purpose the test specimens are subjected to a specified number of opening and closing cycles. The number of cycles depends on the aimed class or national requirements.

Notified product certification body (NPZ) Partner of TÜV Nord Cert as certification body (Construction Products Regulation / Bauproduktenverordnung))

Our cooperation within the TÜV NORD GROUP allows us to provide all services and tests within the scope of the product standard EN 16034 as well as EN 13241 or EN 14351-1, which result in the CE marking by the manufacturer.
This of course also includes the certification of construction products as an notified product certification body.

Partner of the PfB as testing and certification body

The PfB Test Centre for Construction Elements in Stephanskirchen near Rosenheim and the DMT Test Laboratory for Fire Protection will work more closely together in future. Both have signed a cooperation agreement to this effect.

The PfB is approved as an accredited and notified testing and certification body for a large number of tests on construction products. The PfB is able to perform all tests (except fire tests) for doors, windows, gates, facades, roller shutters and their fittings. In addition, the PfB offers a wide range of special tests.

It is also possible to have certification carried out by the internal PfBcert certification body. Among other things, components with properties regarding fire and smoke resistance are also certified.

Especially certifications according to EN 14351-2 (exterior doors) and in the future EN 14351-1 (interior doors) can be provided by this cooperation.

Partner of TÜV Nord Systems for measurement of sound insulation

[Translate to English:] Schallkammer

In Lathen, there is a test stand for airborne sound insulation according to DIN EN ISO 10140, DIN EN 1793-2, which means that through cooperation within the TÜV Nord Group, building products such as facade elements, sound insulation walls, partitions, windows, doors and gates can be tested for airborne sound insulation.  A sound insulation value of R'max,w = 72 dB can be reached.

Professional supervision is provided by experienced TÜV NORD experts in a test laboratory accredited by the DAkkS according to DIN EN ISO/IEC 17025. Further expert advice from TÜV NORD's sound experts (measuring body announced in accordance with § 29b BImSchG) can be obtained at any time.
