适用范围：This part of IEC 61249 gives requirements for properties of epoxide woven E-glass laminated sheet 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The flammability rating is achieved through the use of brominated fire retardants contained as an integral part of the polymeric structure. The glass transition temperature is defined to be 120 ℃ minimum. Some property requirements may have several classes of performance. The class desired must be specified on the purchase order otherwise the default class of material will be supplied.
