Unless otherwise stated ， all the inspections are carryout under the following condition

除非有特别的规定，检验条件按以下执行。

The following standards only apply to the visible area. As long as function good non-visual

area appearance can be ignored. Available deerskin with petroleum ether, a clean stains do not

apply to the exterior standard. If debris in a certain direction is perpendicular to the direction of

three times the length of that line debris; the insulation as granular debris; the silver carbon glue as

a rejection of defects.

以下标准只适用于可视区。只要功能良好非可视区的外观可忽略。可用鹿皮沾石油醚，擦干净

的污渍不适用于该外观标准。如 果杂物某方向的长度是垂直方向的 3 倍则认为是线状杂物；多出的

绝缘点看作粒状杂物；多出的 银碳胶视为拒收缺陷。
