What is EN14509
EN 14509 specifies requirements for factory-produced, self-supporting, double-skinned metal-faced thermal insulation sandwich panels (for use as a separating layer between roofs and roof coverings or between external walls and wall coverings). The core materials used for thermal insulation include rigid polyurethane, expanded polystyrene, extruded polystyrene foam, phenolic foam, foam glass, and mineral wool.
EN 14509 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 core material of the sandwich panel. The four-point bending test is used for this purpose. The shear modulus is calculated from the load-deflection curve using the ultimate load at which the test specimen breaks in shear.
When designing the bending fixture, it is essential to minimize wobbling or rebound, and the load plate in contact with the sample should be wide enough to prevent damage to the surface of the core material. The maximum test load depends on the thickness and material type of the core material but is usually less than 50 kN. For this test, we recommend using a universal testing machine to calculate the shear strength and shear modulus values automatically.

EN 14509:2013–Main test items for metal thermal insulation sandwich panels for building
1. Shear strength and shear modulus
2. Creep coefficient
3. Compressive strength or compressive stress
4. Shear strength after long-term loading
5. Cross panel tensile strength Tensile strength
6. Bending moment capacity and wrinkling stress Bending resistance and wrinkling stress
7. Bending moment capacity and wrinkling stress over a central support
8. Thermal transmittance
9. Reduction of tensile strength with time as a consequence of aging (durability) Tensile strength as a result of aging
10. Resistance to point loads and access loads–ceiling panels and roofs
11. Reaction to fire
12. Dimensional tolerances for sandwich panels
EN 14509:2013–3 types of certification systems for metal sandwich panels for building use
AVCP System 1 certification system: EU Bulletin No. Preliminary type test, on-site audit, EU Bulletin No. issue certificate
AVCP System 3 certification system: EU Bulletin No. Preliminary type test, EU Bulletin No. issue certificate
AVCP System 4 certification system: preliminary type test, manufacturer's self-declaration
According to System 1, the higher the fire rating, the more likely EN 14509 CE certification is required.
