scope:
This specification specified requirements for properties of woven E-glass laminated sheet of a thickness of 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copperclad.
The glass transition temperature is defined to be 150°C minimum. The relative permittivity is equal or less than 4.1 and dispassion factor is equal or less than 0.0120 at 1 GHz.
Some property requirements may have several classes of performance. The class desired shall be specified in the purchase order otherwise the default class of material will be supplied.
