Broad meaning of the shell content, such as: there are some chassis and bottom heater, which did not install any electrical components within, but to play a supportive role in the working process equipment, there will not be have a "temperature", which also need to "flame" it?7 y+ D# D0 V/ R4 v3 _
How: For a "heating" function of the air conditioner standards: IEC-60335-2-40, why there isn’t this request? - v5 K/ u6 L4 KWhat’s the original intention of the specification 30.101 in IEC 60335-2-30? , {; K0 _ n5 b* E, n$ E在IEC60335-2-30第30.101条规定：“基本上由非金属材料构成的风扇式加热器的外壳应能耐燃”。外壳的内涵含义广泛，如：有一些加热器的底盘和底盖，其内没有安装任何电气部件，只是起支撑作用，在器具工作过程中，也不会有产生“温升”，这还需要“阻燃”吗？ % R) e! x7 B, B8 g1 a试问：对具有“制热”功能的空调器标准：IEC-60335-2-40，为什么没有这样的要求呢？$ i p6 C1 n' \# Y4 o) j
制定IEC60335-2-30第30.101条要求的“初衷”和“用意”是什么？: A1 |. @. M; A+ D* C; t c
Field experience has shown that the fire risk introduced by the heating function of an air-conditioner is much less than the fire risk introduced by Fan heaters having an enclosure of substantially non-metallic material ( \! C& x6 U/ o" q" YFan heaters having an enclosure of substantially non-metallic material have been the cause of many fires and have been subject to product recalls around the world. The intention of 30.101 was to try of reduce the fire hazard due to fan heaters. TC 61 is introducing much more onerous test requirements Fan heaters having an enclosure of substantially non-metallic material because the current requirements are not sufficient. 3 [" a: M" _* N. s8 ^1 m试验表明制热功能的空调器引起火灾的风险要远低于全非金属外壳风扇式加热器引起火灾的风险。 6 Q/ n/ F3 C* V, n! f风扇式加热器的全非金属外壳是许多火灾的起因，而且相关产品正在世界范围内被召回。30.101旨在降低风扇式加热器的火灾危险。由于电流要求不够充分，TC61正在针对非金属外壳的风扇式加热器提出更多责任性的试验要求。9 V: E* D/ Y9 v% B 作者: 浪子边城 时间: 2012-6-21 16:52
