这台实验室电源有个露在外面的涂有黑色油漆的铝合金散热器,容易接触,温度超过限值。" V1 d# [9 I0 t* d
IEC61010-1:2001标准如下说:8 W4 G( ~. \2 @. _
If easily touched heated surfaces are necessary for functional reasons, they are permitted to

我的问题:6 b, j6 A9 I6 R8 h. a& m
1。那么散热器露在机器外面散热属于功能原因哇?如果属于功能原因的话贴个高温标志就行了。$ v4 I% R: L/ ?3 K3 W
2。这个铝合金散热器外表涂有一层较薄的黑色油漆,那么这个易接触的表面是不是就该属于非金属? |
