This section of IEC 61249 outlines the properties required for brominated epoxy cellulose paper reinforced core/woven E-glass reinforced surfaces, with a specified flammability (vertical burning test) ranging from 0,80 mm to 1,70 mm in thickness. The flammability rating is achieved through the use of brominated fire retardants that react as part of the epoxy polymer structure. The glass transition temperature is defined to be at least 75°C.
Some property requirements may have multiple performance categories. The category desired must be specified on the purchase order; otherwise, the default category of material will be supplied.
