适用范围：This part of IEC 61249 gives requirements for properties of non-halogenated phenolic cellulose paper copper-clad laminated sheets, economic grade, in thicknesses of 0,8 mm up to 3,2 mm. This standard covers materials with different requirements on flammability and are designated according to the following: Material 61249-2-23-1: general purpose grade, requirement on flammability not specified; Material 61249-2-23-2: materials of defined flammability (vertical burning test). These grades of material provide for one of two flammability requirements and designated as FV0 or FV1 in Table 8. 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 may be supplied.
