1) The International Electrotechnical Commission (IEC) is a global standardization organization composed of the Electrotechnical Committees of its member countries (IEC National Committees). The mission of IEC is to promote international cooperation on all issues related to standardization in the electrical and electronic fields. To this end, IEC, in addition to other activities, also promulgates international standards. The formulation of standards is entrusted to technical committees. Any IEC National Committee interested in the issues involved may participate in this work. International organizations, government agencies and civil society groups associated with IEC may also participate. IEC and the International Organization for the Promotion of Standards (ISO) work closely under the conditions stipulated in the agreement between the two organizations. 2) The formal resolutions or agreements of IEC on technical issues formulated by the technical committees in which all the national committees concerned participate express as closely as possible the international consensus on the issues involved. 3) The standards, technical reports or manuals they publish are recommended 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. IEC Any inconsistency between the standard and the corresponding national and regional standards shall be clearly stated in the national and regional standards.
5) The EC does not provide a recognition mark and does not assume any responsibility for any equipment claiming to conform to one of its standards. This part of the IEC 60335 international standard was prepared by IEC Subcommittee 61E\Safety of commercial electrical food processing and serving equipment under IEC Technical Committee 61 "Safety of household and similar electrical appliances\Technical Committee 61". It constitutes the second edition of IEC 60335-2-50, superseding the first edition published in 1989 and its amendment No. 1 (1990). The text of this standard is based on the following documents: DIS

In addition, IPX0, IPX1, LPX2, IPX3 and IPX4 appliances shall be subjected to the following splash water test for 5 minutes. The test is carried out using the apparatus shown in Figure 101. During the test, the water pressure should be adjusted so that the water splashes 150 mm from the bottom of the bowl. For utensils normally used on the floor, the bowl is placed on the floor, while for all other utensils, the bowl is placed on a horizontal support surface 50 mm below the lowest edge of the appliance. The bowl is then moved around the appliance so that the water splashes on the appliance from all directions. Care should be taken not to direct the water jets at the appliance. 15.1.2 The following amendments are made to this clause:

Compliance is checked by the following test: Appliances with type X connections, except those fitted with specially prepared cords, shall be fitted with the lightest permissible flexible cable or with a cord of the smallest cross-sectional area specified in 26.2. Other appliances shall be tested in the delivery condition. Appliances with appliance inlet sockets may be tested with the associated connector in place or without it, whichever is the more unfavourable. Remove removable parts.
Fill the water tank and steam generator of manually filled appliances completely with water containing approximately 1% sodium chloride (NaCl) and then fill evenly with an additional amount equal to 15% of the capacity of the container but not more than 10 L over a period of 1 min. Fill the food containers of a dry heat warmer with water and then fill each container with an additional amount of 1 L. Connect appliances filled with water using a manually operated switch or an automatically operated valve to a water source with a maximum water supply pressure corresponding to the manufacturer's requirements. The means for controlling the inlet of water remain fully open and water is continued for 1 min after overflow has occurred or until another protective device operates to stop the inlet of water.
The appliance is then immediately subjected to the electrical strength test of 16.3 and inspection shall show that there is no trace of water on the insulation which could reduce creepage distances and clearances below the values specified in 29.1. 15.3 This clause is supplemented with the following:

Compliance is checked by the following test: The appliance is connected to a water supply having the maximum water pressure required by the manufacturer and the water inlet valve is fully open for 1 min. Tiltable and movable parts, including covers, are tilted or placed in the most unfavourable position. The rotatable outlet of the water valve is so positioned that the water flows towards those parts which would produce the most unfavourable result. Immediately following the above treatment, the appliance is subjected to the electrical strength test specified in 16.3. 15.102 Appliances or removable electrical parts which are partly or completely immersed in water for cleaning shall be adequately protected against the effects of immersion. Compliance is checked by the following test: The sample is operated under normal operating conditions with the supply voltage being such that the power input to the appliance is 1,15 times the rated power input until steady state conditions are reached.
Then the connectors are disconnected or the supply is switched off, as appropriate, and the sample is immediately emptied and completely immersed in water at a temperature between 10 °C and 25 °C to the depth indicated if a flooding line is marked. After flooding for 1 h, remove the sample from the water and dry it, taking care to ensure that all the water on the insulation near the input pins of the appliance is removed. Then measure the leakage current on the assembled appliance as described in 16.2. The leakage current shall not exceed the limit specified in 16.2. After the above treatment and measurement of the leakage current, the sample shall be subjected to the electrical strength test specified in 16.3, but the test voltage is reduced to 1000 V
. The sample is then operated as above for 10 days (240 hours). During this period, the sample is allowed to cool to near room temperature 5 times at regular intervals. After this, the connector of the sample is disconnected or the power supply is turned off. The sample is immediately emptied and immersed in water again as above for 1 h. The sample is then dried and the leakage current is measured again as described in 16.2. The leakage current shall not exceed the limit specified in 16.2. The sample shall then be subjected to the electrical strength test as specified above. Visual inspection shall prove that water has not visibly entered the device. Previous: When visually inspecting whether water has entered the appliance, special attention should be paid to the parts of the appliance with electrical components. 16 Leakage current and electrical strength
