Note: If the arithmetic average of the sample thickness is between
the both thickness 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 water absorption shall use the one of 0.4mm.
If the nominal thickness is 25mm and the average of the laminates is over 25mm,
it the requirement value of 25mm shall be used. If the thickness of the laminates
is over 25mm, it shall be processed to 22.5 mm by one-side frame and the surface
shall be smooth.

Note:
1.Electric strength perpendicular to layer direction at 902
  oil can optional choose one of 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, its electric strength perpendicular
  to layer at 902oil 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 nominal 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 1055before tested, then
 turned it to the hot oil at once.
