This part of IEC 61249 specifies requirements for properties of modified brominated epoxide woven E-glass laminated sheet of a thickness 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The glass transition temperature is defined to be 170 \u00b0C minimum.<\/p>\n

Its flame resistance is defined in terms of the flammability requirements of 7.3.<\/p>\n

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.<\/p>\n
