寻求高人指点：
澳洲认证，产品：Fan heater
澳洲针对Fan heater（室内加热器）最新2009版标准AS/NZS 60335.2.30: 2009 clause 30.2.1章规定：
30.2.1 Modification:
The glow-wire test is carried out on enclosures at a temperature of 650 °C.
Addition:
For fan heaters having an enclosure of substantially non-metallic material, the non-metallic
material
– in the enclosure, in fan blades and in all structural elements within the enclosure;
– in components such as thermostats, thermal cut-outs, switches and the like that are
mounted within a distance of 25 mm from a heating element;are subjected to the following tests.
Such parts shall withstand the glow-wire test of IEC 60695-2-11 without ignition, the test
being carried out with a severity of 850 °C. However, the glow-wire test is not carried out on
parts of material classified as having a glow-wire ignition temperature according to
IEC 60695-2-13 of at least 875 °C.
我的理解是只要是产品外壳内部所有的塑胶零部件都需要做850度的灼热丝测试，而且一点火都不能起，也就是不是按照通常的判定方法：点火30秒，移开后30秒要熄灭来判定。
问题点是：哪些部件需要测试灼热丝，标准表达得非常模糊。以上in the enclosure, in fan blades and in all structural elements with the enclosure都用到了3个in, 是指外壳里，风扇叶片里，和外壳内部的结构性元件吗？
什么是外壳内部结构性元件？
上面讲到的substantially non-metallic material 是什么意思？
判能找到高人指点！

谁有AS/NZS 60335.2.30: 2009这份标准？可否提供一下？

应该是带电体和电器元件要通过850度灼热丝试验。因最近几年每年出货去澳洲和新西兰，送认证和他们那边实验室也是怎么理解的。
