真空吸尘器（输入27Vdc, 0.5A,含可拆卸可充电电池模块，输入口在电池模块上）+适配器（输入100-240V~，50/60Hz,输出27Vdc,0.5A,适配器有认证报告及证书），请大佬帮忙解答下下面几个问题：


1. 做国际和国内，真空吸尘器+适配器按照 Class II 器具评估，还是按照Class III器具评估？

2. 若按Class II器具评估，哪些条款可以豁免或者说不用测试及在报告中N/A？若按Class III器具评估，测试中或报告中需要对适配器做出评估吗，哪些条款可以豁免或N/A？

4. 仅针对真空吸尘器三类器具结构，需要做抗电强度测试、泄漏电流测试吗？

1带适配器肯定是II类；
, N# p  }/ o4 e( i6 B" t& @2 j8 U2看具体结构如果没有功能地，盲猜豁免27章节；
3盲猜器具是锂电池，适配器给充电，充电和运行我可能两个都会考虑摸一下；
4盲猜器具是锂电池，适配器给充电，如果电池电压低于8.1.4的话不考虑；
5必须拆了看结构，就怕是Y1电容和数字隔离芯片

请教：Class III appliance需要进行泄漏电流和500V耐压测试，怎么理解？是仅针对42.4V-50VDC之间的Class III结构吗？包括3.3.13中提到的Basic insulation may be required in addition to supply at SELV.

要符合新電池指令法規啊 (EU)2023/1542

是的仅针对不满足8.1.4的安全特地电压部分需要考虑13章节500V的耐压测试。

3 t8 w. w" v4 E0 e9 jI'm safety project engineer of household electric appliances. I have three questions in IEC60335-1:2001 to discuss with you:
' V3 o5 B% }- i3 a" T5 HQuestion 1:The definition of the Class III appliance is: appliance in which protection against electric shock relies on supply at safety extra-low voltage and in which voltages higher than those of safety extra-low voltage are not generated:
) w3 D8 X* d9 Z4 ^9 }: {But we know, according to the Clause 8.1.4, the conductor supplied by safety extra-low voltage may be live part if the peak value of the voltage exceed 42.4V. So, the safety of Class III appliance can't only relay on the safety extra-low voltage but also basic insulation if applicable. Just same for Class III construction.
Question 2: The definition of the Basic insulation is: insulation applied to live parts to provide basic protection against electric shock That means if there is no live parts, there is no basic insulation too. But according to the Clause 13.3, we must carry out the 500V electric strength test on the basic insulation of SELV, but SELV may not be live if compliance with the Clause 8.1.4. If the part is not considered to be live, the basic insulation which can withstand the 500V electric strength should not be necessary. In fact ,the two questions  are relative.
. C6 h8 i) k+ T0 GQuestion 3: Clause19.13: "When the insulation, other than that of Class III appliances....." The "Class III appliances" should be replaced by "Class III appliances and Class III construction"

谢谢~ 总算找到相对官方的技术判定了
