Scope

This Part of GB/T 16935 specifies the dimensioning of clearances and creepage
distances for spacings equal to or less than 2 mm for printed wiring board and
equivalent constructions, where the clearance and the creepage distance are identical
and are along the surface of solid insulation, such as the paths described in 6.2 of Part
12) (Examples 1, 5 and 11).

Summary	This standard specifies the printed circuit boards and similar structures not exceeding 2mm clearances and creepage distances method for determining the size, in these structures, clearances and creepage distances are the same and are along the surface of the solid insulation, such as part 1 of 2) in the path described in 6. 2 (Examples 1, 5 and 11). The size determination method than the method specified in Part 1 is more accurate. But if you do not require precise dimensions, Part 1 content may apply. This section can only be used as a whole, does not allow this part excerpt from one or several use, but also allow them to replace the corresponding provisions of Part 1 to use. And this part can only be used in conjunction with Part 1.
