en 14509Requirements are set for factory-produced, self-loading, double-walled metal-faced sandwich panels (partitions used for cladding between roofs and roof cladding, and between exterior walls and walls). Thermal insulation core materials include rigid polyurethane, expanded polystyrene, extruded polystyrene foam, phenolic foam, foam glass and mineral wool.
The EN14509 standard specifies a number of requirements for the mechanical strength of sandwich panels, including the determination and specification of the shear strength and shear modulus of the sandwich core material. The test uses a four-point flexure test, which calculates the shear modulus from the load deflection curve by testing the ultimate load of the sample at shear fracture.
The most important thing in the design of the bending fixture is to minimize shaking or **, and the load plate in contact with the sample should be of sufficient width to prevent damage to the surface of the core board. The maximum test load depends on the thickness of the core board and the type of material, but is typically less than 50 kN. For this test, we recommend using a universal testing machine, which automatically calculates the shear strength and shear modulus values.

EN 14509:2013 Self-supporting double-layer metal surface insulation sandwich panels - Factory-made products - Specification.
This European standard specifies the requirements for factory-manufactured self-supporting double-layer metal face laminates for discontinuous laying in the following applications:
a) Roof and roof cladding.
b) Exterior walls and wall cladding.
c) Walls (including partition walls) and ceilings within the building envelope.
The insulating core materials covered by EN14509 are rigid polyurethane, expanded polystyrene, extruded polystyrene foam, phenolic foam, honeycomb glass and mineral wool.

*CP System 1 certification system: EU Gazette Preliminary Type Test, On-site Audit, EU Gazette Number Issuance Certificate.
*CP System 3 certification system: EU Gazette number preliminary type test, EU Gazette number issuance certificate.
*CP System 4 certification system: preliminary type inspection, manufacturer's self-declaration.
The specific choice of which certification system needs to be decided in combination with the actual use of the product and the fire rating, you can consult Ruidu, the higher the fire rating, the higher the EU CE certification of EN14509 is generally required according to system 1.
