是的,标准里没提到带调速的,不过你看一下5.2.1.1,有这么一句话,5.2.1.1 Normal load shall be considered to be that load which approximates as closely as possible the most severe conditions of normal use but is not a deliberate overload. A multifunction appliance is to be tested individually for each applicable normal load.(大概意思是,正常负荷是最接近正常使用中最严重状况下的负荷,但不是故意的超负荷)
那么你认为什么状态下是正常负荷?
