Exposed wire tolerance limit of coating resin part on product side.
Size of exposed wire occurring to coating resin is specified below.
1. Width direction（dimension a）
：Acceptable
when a≦w/2
Nonconforming when a＞w/2
2. Length direction（dimension b）
：Dimension
b is not specified.
3. The total area of exposed wire occurring to each sides is
not greater than 50% of coating resin area, and is acceptable.
