UNE-EN IEC 61249-2-46:2018

This part of IEC 61249 gives requirements for properties of non-halogenated epoxide non

woven reinforced core/woven E-glass reinforced surface laminate sheets of thermal

conductivity and defined flammability (vertical burning test), copper-clad for lead-free assembly

in thicknesses of 0,60 mm up to 1,70 mm. The flammability rating is achieved through the use

of non-halogenated fire retardants reacted as part of the epoxide polymeric structure. The

glass transition temperature is defined to be 105 °C minimum. Thermal Conductivity is defined

to beÿ1,5±0,20ÿW/m·K.

Some property requirements may have several classes of performance. The class desired

should be specified on the purchase order, otherwise the default class of material will be

supplied.
