GB4706.19的问题

19.4 The appliance is tested under the conditions specified in clause 11. Any control that
limits the temperature during the test of clause 11 is short-circuited.
NOTE If the appliance incorporates more than one control, they are short-circuited in turn.
19.5 The test of 19.4 is repeated on class 0I appliances and class I appliances
incorporating tubular sheathed or embedded heating elements. However, controls are not

貌似只对用氧化镁等吸湿材料作为绝缘材料制成的管状外鞘的电热元件才需要。
用PVC或硅橡胶等材料作为绝缘材料的管状外鞘的电热元件不用做19.5。
