电极式加湿器SAA认证

请问 电极式加湿器 60335-2-98 有谁做过没有，客户的电极直接和水接触，容器是塑料的单层绝缘，依据60335-1 clause 22.33，应该是不符合要求的吧？？是否还有别的看法，以前没做过电极式的，现要申请SAA认证，请教下22.33 Conductive liquids that are or may become accessible in normal use and conductive
liquids that are in contact with unearthed accessible metal parts shall not be in direct
contact with live parts. Electrodes shall not be used for heating liquids.
For class II construction, conductive liquids that are or may become accessible in normal
use and conductive liquids that are in contact with unearthed accessible metal parts shall
not be in direct contact with basic insulation or reinforced insulation unless the reinforced
insulation consists of at least 3 layers.
For class II construction, conductive liquids which are in contact with live parts shall not be
in direct contact with reinforced insulation unless the reinforced insulation consists of at
least 3 layers.
An air layer shall not be used as basic insulation or supplementary insulation in a double
insulation system if it is likely to be bridged by leaking liquid.
Compliance is checked by inspection.

请看-2-98，电极加热是允许的:
22.33 Modification:
Liquids may be heated using electrodes and may be in direct contact with their live parts.

注意上面的是modification，-1部分被修改了。

液体和人手触摸到的地方（水的容器）正常使用时要满足最好是双层绝缘，或3层的加强绝缘。并且，接触到水之前的盖子要有联锁装置。

这种方式的加湿器很少的哦。

应当是不允许基本绝缘的，如果是单层绝缘符合加强绝缘的要求，也是可以的吧
