1) The International Electrotechnical Commission (IEC) is a global standardization organization composed of the Electrotechnical Commissions of member countries (IEC National Committees). The mission of IFC is to promote international cooperation on all issues related to standardization in the fields of electrical and electronic engineering. To this end, in addition to other activities, IEC also promulgates international standards. Its formulation work is entrusted to various technical committees. Any IEC National Committee interested in the issues involved can participate in this work. International organizations, government agencies and non-governmental organizations associated with IEC can also participate. IEC and the International Organization for Standardization (ISO) work closely together under the conditions stipulated in the agreement between the two organizations.
2) Formal IEC decisions or agreements on technical questions drawn up by technical committees in which all interested National Committees participate represent as nearly as possible international consensus on the issues involved. 3) The standards, technical reports or manuals they propose are presented in the form of recommendations for international use and are accepted by the National Committees in this sense.
4) In order to promote international unification, the IEC National Committees agree to apply IEC International Standards to national and regional standards as clearly as possible. Any inconsistencies between IEC standards and corresponding national and regional standards shall be clearly stated in the national and regional standards.
5) IEC does not provide a mark of approval and does not assume any responsibility for any equipment claiming to conform to one of its standards. 6) Noting that some of the components of this International Standard may be the subject of patent rights, IEC does not assume any responsibility for identifying any or all such patents.
This part of the IEC60335 international standard was prepared by Subcommittee 61E "Safety of commercial electrical food processing and serving equipment" of Technical Committee 61 of 1EC "Safety of household and similar electrical appliances".

The devices controlling the water inlet remain fully open and water filling is continued for 1 min after any overflow occurs or until another protective device operates to stop the water inlet.
The appliance is then immediately subjected to the electrical strength test of 16.3 and a visual inspection shall show that there is no trace of water on the insulation that could cause creepage distances and electrical spacings to be reduced below the values specified in 29.1. 15.3 This clause adds the following content
Note 101: If it is not possible to place the entire appliance in a wet cabinet, the parts containing electrical components are tested separately, but attention should be paid to the conditions inside the appliance. 15.101 Appliances equipped with a water switch for watering or cleaning should be constructed so that the water flowing from the water switch cannot contact live parts. Compliance is determined by the following test: The appliance is connected to a water source with the maximum water supply pressure required by the manufacturer, and all devices controlling the water inlet are opened for 1 min. Tiltable and movable parts, including covers, are tilted or placed in the most unfavorable position. The rotatable outlet of the water switch is positioned so that water flows to those parts that will produce the most unfavorable results. The appliance should then be subjected to the electrical strength test specified in 16.3. 16 Leakage current and electrical strengthbzxz.net

NOTE Care should be taken to ensure that the capillary is not closed by breaking. 22.103 Signal lamps, switches or buttons indicating danger, alarm or similar conditions shall only be red. Compliance is checked by inspection.
22.104 Drain plugs and other drain devices shall be so constructed that they cannot be opened accidentally and it shall not be possible to remove the drain plug accidentally.
Compliance is checked by inspection and by manual test. NOTE: This requirement is satisfied, for example, if the door handle automatically returns to the closed position when it is released, or if the door handle is wheel-shaped or recessed. 22.105 The means provided for discharging fluid from the appliance shall not affect the insulation during discharge of the fluid. Compliance is checked by inspection and by manual test. 22.106 Portable appliances shall be constructed to prevent hazards caused by objects placed on the table or on the floor penetrating the bottom surface. Compliance is checked by inspection and, where necessary, by measurement. NOTE: Appliances without feet are considered to comply if the distance between each live part and the upper support surface measured through any through hole is not less than 6 mm. For appliances equipped with feet and intended for use on a table, this distance is extended to 10 mm. For appliances intended for use on the floor, this distance is extended to 20 mm. 22.107 The water level mark to which an artificial water-filling appliance must be reached shall be placed in a position that is easily visible during water-filling.

Note 101: In the above case, if it is impossible to move the moving parts of the appliance at the given rate due to reasons such as the mass of the component, the bending rate may be reduced.
After the bending test, the capillary tube shall not show any signs of damage within the meaning of this standard and any damage that would impair its further use. However, if damage to the capillary tube at one point renders the appliance inoperable (fail-safe), the individual capillary tube shall not be tested and the capillary tube installed as a component of internal wiring shall not be checked for compliance. Compliance is checked by breaking the capillary tube. NOTE 102 Take care to ensure that the capillary tube does not seal when broken. 24 Components
