EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61249-2-45 testing. IEC EN 61249-2-45 gives requirements for properties of thermal conductivity and defined flammability (vertical burning test), copper clad non-halogenated epoxide nonwoven reinforced core/woven E-glass reinforced surface laminate sheets.
The degree of flammability is achieved through the use of non-halogenated fire retardants that react as part of the epoxide polymeric structure. The glass transition temperature is defined as a minimum of 105°C. The thermal conductivity is defined as (1,0 ± 0,15) W/(m•K).
The copper clad face shall be substantially free of imperfections that could have an impact on the suitability of the material for its intended use. Scratches deeper than 10 µm or 20% of the nominal thickness of the foil thickness, whichever is lower, are not permitted. Scratches with a depth of less than 5% of the nominal thickness of the foil are not counted unless that depth is 10 µm or more.
The uncoated side of the sheet, which is coated on one side, will have the natural appearance resulting from the curing process. Minor irregularities in color are allowed. The gloss of the uncoated side will be the gloss imparted by the printing plate, release film or release foil used. Changes in gloss due to the influence of the pressure of the gases released during curing are allowed.
