27、rning test), copper-clad 1 Scope This part of IEC 61249 gives requirements for properties of modified non-halogenated epoxide woven E-glass laminated sheet 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The flammability rating is achieved through the use of phosp
28、horus compounds and/or aluminium hydroxide fire retardants contained as part of the polymeric structure. The glass transition temperature is defined to be between 150 C to 190 C. Some property requirements may have several classes of performance. The class desired should be specified on the purchase
29、 order, otherwise the default class of material will be supplied. 2 Normative references The following referenced documents are indispensable for the application of this document.

Scratches with a depth between 5 % and 20 % of the nominal thickness of the foil are permitted to a total len
44、gth of 100 mm for a 300 x 300 mm area. 6.1.4 Raised areas Raised areas are usually impressions in the press plates used during manufacture but may also be caused by blisters or inclusions of foreign particles under the foil. Raised areas caused by blisters or inclusions are not permitted. Raised are
