Self supporting sandwich panels tests according to EN 14509 standard

Sandwich Biegeprüfung EN 14509The requirements for testing sandwich panels (elements) are described in the DIN EN 14509:
"self-supporting double skin metal facing insulating panels - factory made product - specifications".

This standard shows all requirements for prefabricated self-supporting double skin facing insulating panels, which are designed for discontinuous laying for the following applications:

 

  • Roof and roofing
  • Exterior walls and walls covering
  • Walls (including partition walls)
  • Interior ceiling


Sandwich Querzug EN 14509The standard is also dedicated for panels with a treated polyurethane foam, expended extruded polystyrene foam, cellular glass or mineral wool core.

 

Factory production control

DYNA-MESS testing machines can be part of the production control which allows detection of defects and insures the quality of the product.

  • Shear strength
  • Shear modulus
  • Tension strength
  • Compression strength

Standardized tests and automatic properties calculation

Sandwich Vierpunkt BiegeversuchDYNA-MESS offers testing machines with accessories such as 4-point flexion fixture, shear devices and external position measurement sensors to perform a wide range of standardized tests.

DYNA-MESS software calculates automatically all the mechanical properties during the test.

 

Practice-oriented operation

In many cases, DYNA-MESS test machines need to be integrated into the production line. The robust, easy to maintain design, as well as the user friendly software provides an excellent solution for in-process testing.

Vibration stimulaton of structures

 

Schwingungserreger für BaudynamikA servo-hydraulic vibration exciter, a "shaker", is used to dynamically stimulate massive structures such as bridges or houses. The used hydrostat achieves a nominal force of 20kN and a stroke of 100mm. In dynamic operation, this system can run frequencies up to 110Hz. By the use of variable mountable disks masses up to 800kg can be set in vibration.

 

 

 

 

Optimal for mobile use

Mobiles Hydraulik Aggregat für SchwingerregerThe compact machine is mounted on a trolley whereas the hydraulic unit is also mobile. This enables measurements on the sample which can be carried out on-site. The shaker can be operated both, in vertical- and horizontal arrangement. Lateral fastening strips allow it to be screwed to the building structure.

 

Frequency sweep for detailed analysis

Through the software module "Sweep test" the frequency is continuously increased in defined steps. It is also possible to change the amplitude. Evaluations for each frequency or amplitude are included in the module.
