Initial situation

• Resilient or MMF floor coverings show concave or convex deformations or/and gaping of joints when exposed to unusual temperatures, such as solar irradiation.Normative methods make use of only small samples without any joints.
• The simulated heat impact does not correspond with real practice.

Implementation

• The investigations takes place in a research project of IHD, which was started in june of 2019.
• It we‘ll be investigating various test setups (approx. 4.5 m² and approx. 0.5 m²).
• The larger test setup is being installed with various sensors to evaluate the deformation behaviour.
• The thermal irradiation takes place from above of a partial area of the flooring.

State of affairs

• Investigation of the thermally induced deformation behaviour of different floor coverings on the large hotspot setup and on the table hotspot setup.
• Validation of the first treshold to differentiate between thermally stable and unstable product qualities.
