加湿器做完干烧如何判定

加温器做ETL，在做非正常干烧结束后，振荡片处有微熔胶，测试指碰不到带电体，但如加水会漏水，是否符合标准要求。

求高手指点，最好能附上标准条款更好。

有没有去核对过标准的具体要求？是按哪个标准做？加热器的标准很多的

老大，是UL998，平时做美标产品少，欧标做完非正常不会重加水去评估，对美标标准理解也不透彻，所以上来请教高手。有空帮看看，谢谢！

加水打耐压，3A的保险丝要是动作耐压一定过不了的，欧标应该要重新注水打耐压的吧

65 Abnormal Operation Test
65.1 General
65.1.1 If the conditions of normal operation are not representative also of abnormal conditions likely to be
encountered in actual service, the product shall not cause a risk of fire, electric shock, or injury to persons
when operated under such abnormal conditions.
65.1.2 The conditions resulting from abnormal operation of a product shall be confined by the enclosure
when the product is subjected to tests such as blocked armature in a relay, transformer burnout, stalled
rotor, operation without liquids, or other conditions that may be encountered in service.
65.1.3 An electrode-type product shall be operated as described in Clause 65.1.4 until ultimate results are
obtained. The results shall not be acceptable if a nonintegral branch-circuit protector trips during the test.
After the test, the product shall comply with the Starting Test, Clause 55 and the Input Test, Clause 56.
Exception: A product need not be subjected to this test if the water-level-limiting device operates for
100,000 cycles with no mechanical or electrical malfunction or significant pitting or burning of the contacts.
65.1.4 The product shall be mounted as intended and connected to a source of rated voltage. The drain
valve shall be blocked closed, the water-inlet valve blocked open, each water-level-limiting device shall
be bypassed, and the electrodes are to be electrically connected. In addition, the product shall be
mechanically and electrically isolated from any ground means. If the hardness of the water may be a
factor, the test shall be performed with a solution of 0.5 g (0.018 oz) of calcium sulfate (CaSO4) per litre
of distilled water. The product shall be operated until ultimate results are obtained.
65.1.5 A product that is permanently connected to a water supply shall be operated without water.

红字中的不带水工作应该指的是非正常工作中的一个状态，例如堵转、。。。。。、空烧，是这样的吧
