" p  }' ]( }6 P. ?5 n5 b; D6 lIn case of an appliance having grills or openings which permit flame to exit from the appliance and the distance between the external parts and the connection is less than 50 mm (considering the envelope of the vertical cylinder having a diameter of 20 mm and a high of 50 mm), what considerations apply to the parts in contact with the external surface of the appliance?
Decision:
Taking into account the previous discussion in IEC/TC61 about the matter (see minutes of Cape Town meeting 2005 and the relevant Cape Town Chairman Report), it is considered that the flames out the appliance have not taken into account. In case of the drawing, if the enclosure complies with the needle flame, then the appliance withstands the clause 30 test.
