适用范围：This part of IEC 61249 gives requirements for properties of brominated epoxide cellulose paper reinforced core/woven E-glass reinforced surfaces-laminated sheets of defined flammability (vertical burning test), copper-clad in thicknesses of 0,80 mm up to 1,70 mm. The flammability rating is achieved through the use of brominated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 75 ℃ minimum. Some property requirements may have several classes of performance. The class desired needs to be specified on the purchase order, otherwise the default class of material may be supplied.
