Target Condition - Class 1,2,3(⽬标条件 - 1,2,3级)
Insulation material fills the entire area between the PTH and the
metal core without any voids or areas of missing insulation.
整个区域填满绝缘材料,没有任何
洞或绝缘材料缺区域。
Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
Insulating material meets minimum thickness and dielectric spac-
ing requirements.
Voids or resin recession does not cause spacing to be less than
acceptability requirements.
充的绝缘材料足最间距的要求。
空洞或树脂没有造间距低于可接受性要求。
Nonconforming - Class 1,2,3(不符合条件 - 1,2,3级)
Defects either do not meet or exceed above criteria.

Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
Wicking, radial cracks, lateral spacing or voids in the hole-fill
insulation material does not reduce the electrical spacing between
adjacent conductive surfaces to less than 100 µm [0.003937 in].
Wicking and/or radial cracks does not exceed 75 µm [0.00295 in]
from the PTH edge into the hole-fill.
