scope:
This part of IEC 61249 specifies requirements for properties of non-halogenated epoxide woven E-glass laminate sheet of a thickness of 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The glass transition temperature is defined to be 150 C minimum. The relative permittivity is equal to or less than 3,7 and the dissipation factor is equal to or less than 0,007 0 at 1 GHz. Some property requirements may have several classes of performance. The class desired should be specified in the purchase order, otherwise the default class of material will be supplied.
