3 Requirements
In addition to complying with the general requirements of IEC 60626-1, each flexible combined laminate shall conform to the requirements set forth in the appropriate sheet corresponding to its type, as shown in the sheets of this standard.
4 Designation
Table 1 lists material designations and constructions appropriate to each sheet. Material conforming to this specification shall be identified by a designation containing the IEC standard number, the material designation from IEC 60626-1 and the nominal thickness. For example: IEC 60626-3, Sheet 112, P-C/F-PET/P-C, 0,15 mm
