To determine the static friction coefficient between the building protection mat and roof cladding:

Clean roof cladding

Place test specimen on roof cladding

Draw the test specimen parallel to the roof using measurement device

Record result
The testing is based on DIN EN ISO 8295 Plastics
– Film and sheeting – Determination of coefficient of
friction, issue October 2004.
It is necessary to carry out 10 tests, 5 in a dry state, 5 in the wet state. The arrangement of the test has to
be carried out uniformly on the roof surface. Visually different roof areas should be examined separately.
In this case tests have to be repeated accordingly. The roof areas where the test will be made have to be
cleaned before testing. Place the specimen on the roof and wait 30 seconds afterwards. In the next step
the force (F) has to be applied steadily and parallel to the centre of the specimen and measured by the
dynamometer. To determine the coefficient of friction, the decisive force is the maximum force that occurs
prior to the movement of the specimen.

Static friction coefficient µ = F /G
Important information:
You can use the IBC test protocol “Determining static friction coefficients” to help you determine the static
friction coefficients!
06. System design/dimensioning
Proof of the load-bearing capacity of the assembly system is based on valid EN standards. Security
against slipping and lifting off (position stability) is also proven.
The aerodynamic coefficients of the entire system were calculated in a boundary layer wind tunnel in order
to optimise and reduce loading on the system, in accordance with the information sheet „Information on
the manufacture, planning and implementation of solar plants“ from the DIBt.
