I类或III类产品中,产品内部扬声器外壳直流风扇外壳,是否要考量防火测试
I类或III类产品中,产品内部扬声器外壳直流风扇外壳,是否要考量防火测试。就是条款4.7.3.4假定产品外壳为金属外壳。III假定为有做LPS的电源适配器供电,产品同样为金属外壳
同學習,求科普 Inside FIRE ENCLOSURES, materials for components and other parts, (including MECHANICAL
ENCLOSURES and ELECTRICAL ENCLOSURES located inside FIRE ENCLOSURES), shall comply with
one of the following:
− be of V-2 CLASS MATERIAL or HF-2 CLASS FOAMED MATERIAL; or
− pass the flammability test described in Clause A.2; or
− meet the flammability requirements of a relevant IEC component standard that includes
such requirements.
Class I,三選一。Class III, adapter with LPS, 看4.7.2.2就可以了吧 路过学习:) zuo 发表于 2017-11-10 09:45

III类,适配器LPS 但,直流风扇外壳和扬声器外壳如何界定它是否安装在V-1的材料上,元器件只要是PCB有相关认证,且PCB达到V-1,就可以,但这两个如果确定呢? 45550629 发表于 2017-11-13 11:37

PCB都是V-1, 但是扬声器外壳和直流风扇外壳不在PCB上的。 学习了:D :):):):):):):)
