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 3.7 and dispassion factor is equal or less than 0.0070 at 1GHz.
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.
