EN 60335-2-105
22.7 Replacement:Appliances having a steam bath function shall incorporate adequate safeguards against the
risk of excessive pressure.
If jets of steam or hot water are emitted through protective devices, the electrical insulation
shall not be affected or the user exposed to a hazard.
Compliance is checked by inspection and by the following test.
For non-pressurized boilers, the water shall be supplied at a pressure not exceeding 150 kPa.
For pressurized boilers, the maximum pressure occurring during the test of Clause 11 with the
boiler filled but without steam emission is measured. All pressure-regulating devices
that operated during the test are rendered inoperative and the pressure measured again. The
pressure shall not increase by more than 200 kPa.
Any pressure-limiting protective device is then rendered inoperative and the pressure in
the boiler is raised hydraulically to five times the pressure measured originally or twice the
pressure measured with the pressure-regulating device operating during the test of Clause 11
rendered inoperative, whichever is higher. There shall be no leakage from the boiler.
请教有哪位大侠做过EN60335-2-105的22.7这个章节的测试?能否帮讲解一下这个测试怎么做,如何去理解这个条款?
什么叫做是non-pressurized boilers; pressurized boilers 它们的定义是什么啊?
万分感激! 楼主怎么发贴到这儿来了？？？ 这里 http://www.angui.org/bbs/read.php?tid-239-keyword-60335.html 有新版吗？旧版什么时候过期？
