dmakers, compliance is also checked by the test of 11.Z103.

(简译: 面包机需要满足11.Z103的测试)

Products classification: please see Page 24 of EN 60335-2-9

 

11.3 Addition:

For flat surfaces, temperature rises are measured using the probe of Figure Z101. The probe is

applied with a force of 4 N ± 1 N to the surface in such a way that the best possible contact

between the probe and the surface is ensured.

NOTE Any measuring instrument giving the same results as the probe may be used.

(简译: 对于平坦的表面温升测量, 需要用图Z101的测试探棒来测, 探棒与接触表面的压力为4 N ± 1 N )

建议: Means that the thermocouples can be use if non-flat surface.

(如果不平坦的表面, 直接用热电偶线测量也可符合)

  

 

11.8 Addition:

The temperature rise of handles or grips and that of operational devices such as switches, keypads

   and knobs that are intended to be touched in normal use is measured as follows:

(简译:在正常情况下接触的手柄,把手,旋钮,开关按键等按以下要求测试)

 

1. for operational devices and grips with a surface greater than 300 mm2,over an area of 20 mm

    around the part normally gripped or touched to operate the appliance.

(简译:对于正常情况下接触面积大于300 mm2部位,需超出20mm范围内测量)

 

2. for operational devices and grips with a surface less than or equal to 300 mm2, over an area of

    25 mm around the part normally gripped or touched to operate the appliance.

(简译:对于正常情况下接触面积小等于300mm2部位,需超出25mm范围内测量)

 

The distance is measured along the surface as for creepage distances unless it is evident from the

construction that the hot part cannot be touched unintentionally.

(简译:这个距离是沿着表面的测量距离, 除非结构能够保证热表面不会以外接触到)

 

3. for handles, over an area of 20 mm around the orthogonal projection of all points located at a

clearance less than 40 mm between the rear (inner) part of the handle or at least 80 mm along the

handle (whichever is the more unfavourable) and the hot part, unless it is evident from the

construction that the hot part cannot be touched unintentionally (see Figure Z102).

(简译: 对于把手结构,手柄的内表面到接触面小于40mm部分直角投影到接触向外拓展20mm的范围需要测量,

         或者沿着手柄80mm直角投影到接触向外拓展20mm的范围需要测量,两者取最不利的,见下图)

* 如果结构能够保证热表面不会接触到,热表面无需测量。

  

11.Z101

Ovens, rotary grills and cookers are placed as specified in 11.2. The appliance is supplied at

rated power and operated under normal operation.

All heating units that can be connected to the supply mains at the same time during normal

use ar
