Note:
1.             Electric strength perpendicular to layer direction at 90± 2° C Coil can optional choose one 20s raising voltage class by class and the requirement of voltage resistance test for 1 min. If the material is conform with one of the both methods, the electric strength shall be considered to be also conform with the standard.
2.             If the arithmetic average of the sample thickness is between the both thicknesses listed in the above table, its requirement value shall use the interpolation method to get. If the average is below 0.4mm, the requirement value of electric strength shall use the one of 0.4mm, If the normal thickness is 3mm and the average of the sample thickness is over 3mm, the requirement value of 3mm shall be used.
3.             3020 type shall be pre-conditioned for 96h at 105± 5 ° C before tested, then turned it to the hot oil at once.
