5.3 Resistance to fixings

in case of HPL composite panels the Resistance to fixings shall be determined according to ISO

13894-1, clause 15.
5.4 Bonding strength

The bonding strength shall be determined according to ISO 13894-1 clause 10: Perpendicular tensile

strength.
5.5 Direct airborne sound insulation

The Direct airborne sound insulation shall be measured as described in EN ISO 10140-2.

5.6 Flexural tensile strength

The flexural tensile strength of HPL composite panels shall be determined as perpendicular tensile

strength according to ISO 13894-1 clause 10. The result(s) shall be declared and expressed in MPa.

The flexural tensile strength of compact laminate panels shall be determined as flexural strength and

flexural modulus of elasticity measured in the transverse direction according to EN ISO 178, at a

machine crosshead speed of 10 mm/min. The result(s) shall be declared and expressed in MPa.

5.7 Thermal resistance/conductivity

The thermal resistance/conductivity shall be determined in accordance with EN 12664 or can be

calculated from data taken from EN ISO 10456.

When calculating the thermal conductivity of the HPL composite panels, the contribution of HPL is to

be considered as 0,3 W/(m K)
