请教商用款搅拌机输入功率和正常温升测试

请教大老,商用款食物搅拌机(Food blender)输入功率和正常温升测试如何测试,看不懂3.1.9


1.overload release operates 是否同11.8的Protective devices,这样额定电压保护装置都快动作,正常1.06 倍不是更容易动作了?
2.with the highest temperature has been attained. 如何获得最高温度,加载到多大(快到堵转状态吗)

3.产品额定功率如何选定,感觉这温升测试不太好过,第一次接触这类产品,请大神支招。
4.mechanical brake.设备是怎样的,如何购买。
谢谢!




3.1.9 Addition:
IEC 60335-2-64:2021 +AMD1 :2024 CSV
© IEC 2024
operation of the appliance under the following conditions:
The appliance is operated without load. The appliance is then loaded in appropriate steps, the
supply voltage being maintained at its original value. For each step, steady conditions have to
be established before increasing the load. This operation is repeated until just before an
overload release operates, or until the steady condition with the highest temperature has been
attained.
Note 101 to entry: The load may be achieved by using an electrical or mechanical brake.
Where it is not possible or is impractical to apply effectively an electrical or mechanical brake,
the load is 115 % of the input measured when the appliance is operated without load at rated
voltage and normal operating temperature, and with controls intended to be adjusted by the
user set at maximum.
Note 102 to entry: Examples of such appliances are
- liquid blenders;
- slicers;
- peelers;
- coffee grinders;
- machines used for washing and/or drying food;
- portioning machines.

-14确实是最难做的一个标准,比-9还烦:lol

商用液体搅拌器可以按空载实测功率的1.15倍。和面机类似的可以加面团做机械负载直到接近保护状态。
