GB 4706.13—2004/IEC 60335-2-24:2000 This part is a revision of B4706.13.-1999 "Particular requirements for safety of household and similar electrical appliances - refrigerating appliances, ice cream machines and ice makers". This part is equivalent to 1EC60335-2-24:2000 "Particular requirements for safety of household and similar electrical appliances - refrigerating appliances, ice cream machines and ice makers". This part should be used in conjunction with 34706.1-1998 "General requirements for safety of household and similar electrical appliances" (equivalent to 1EC60335-1:1991 and its first supplement). The main differences between this part and B4706.13-1998 are as follows: a) In Chapter 2, the definitions of refrigerating appliances, heating systems, flammable refrigerants and free passage of ice cream machines are added. b) In Chapter 3, "Note 101: Appliances using non-flammable refrigerants do not consider the additional hazards caused by the use of flammable refrigerants."
This standard is aimed at the ignition hazard of flammable refrigerants caused by leakage of potential ignition sources related to the appliance. The ignition hazard of flammable refrigerants caused by leakage of external ignition sources related to the environment where the appliance is installed is compensated by adopting a small probability of ignition. "c) In Chapter 4, 4.3 is revised to * Before the initial test, the ice cream machine should be operated at no load for 1 hour at the rated voltage or at the maximum setting time of the installed timer, whichever is shorter:
Other compression appliances should be operated at rated voltage for at least 24 hours, then disconnected and placed for at least 12 hours. 4.7 is revised to *32℃ for sub-temperate (SN) and temperate (N) appliances: 38℃ for subtropical appliances (ST): 11℃ for tropical appliances (T): 43C ± 1℃."
d) Chapter 7+.7.1 Add "Rated input power (W) or rated current (4) shall be marked on the appliance, except for compression appliances (excluding ice cream machines), which are only required to be marked with rated current (A): and separate requirements for single refrigerant and mixed refrigerant; Add the chemical name of the main component of the foam layer material or the refrigerant number. "e) In Chapter 8, 8.1.1 is modified to replace the second paragraph of the test regulations with the following content: If the appliance can be isolated from the power supply by a plug or a full switch, the lamp is not removed, but during the replacement of the lamp, it should be ensured that the live parts of the lamp cap are protected from direct contact."
f) In Chapter 13, add 13.1\13. 2 Tests are not applicable to battery circuits. \Change 13.2 to\Replace the values specified for Class 01 appliances and various types of Class 1 appliances with the following values:.--01 Class I appliances
Class II appliances
In Chapter 15, 15.103 is added. For the requirements of appliances other than built-in play appliances, ice machines and ice cream machines, 15.105 is added. The operation of the defrost system shall not affect the electrical insulation of the defrost heating element. Compliance is checked by the following test: Immediately after the test of 11.102, the appliance shall be subjected to the electrical strength test specified in 16.3 and inspection shall show that there is no water on the insulation that could reduce the electrical distances and clearances below the limits specified in 29.1. In addition, if visual inspection shows that water has come into contact with the defrost heating element or its insulation, the device shall be able to withstand the test of 22.102. "
h) In Chapter 16, 16.3 adds to the table the following note: "Where the test voltage is applied: In the absence of a circuit driven solely by a battery and a circuit supplied by the mains".
GB4706.13--2004/IEC 60335-2-24:2000i) In Chapter 19, 19.104° lighting devices should not create any fire hazard under abnormal working conditions\ Test method Add 19.105\ Appliances intended to be powered by batteries and marked with forging marks on or near their terminals or terminal devices are constructed so that the risk of fire, mechanical damage or electric shock can be avoided when the polarity is reversed. The appliance works under the conditions specified in Chapter 11, but a fully charged 70Ah battery is connected to the opposite polarity, and its compliance is checked by this test.
During and after the test period, the appliance shall comply with the requirements of 19.13. j) In clause 20, amend 20.1 to read: "Ice cream machines shall have adequate stability." Add 20.101: "Refrigerating appliances and ice machines shall have adequate stability." - Add 20.102: "Tests to be applied to appliances with doors, 20.103: Tests to be applied to appliances with sliding drawers in food storage compartments, 20.103: Tests to be applied to appliances with sliding drawers accessible without opening the door." k) In clause 21, add 21.102: "Lamp caps shall be protected against mechanical impacts. Compliance is checked by testing with a sphere of 75 mm ± 0.5 mm diameter, which is brought as close to the cap as possible after the lampshade is fitted without applying appreciable force.
The sphere shall not touch the cap. \
1) In Chapter 22, 22.7 is added: Compression appliances using flammable refrigerants, including protective external elements of the protected cooling system, should be able to withstand the test.
22.104 "Appliances with two or more temperature control devices for controlling the same motor-compressor should not cause inappropriate operation of the motor thermal protector of the motor-compressor" test method is added. 22.105\ For appliances that can be powered by both the mains and batteries, double insulation or reinforced insulation should be used between the battery circuit and the live parts. In addition, it should not be possible to touch the live parts when the battery is connected. This requirement also applies to non-detachable parts that must be removed when connected, such as covers or other parts: compliance is determined by regulatory inspection and prescribed tests on reinforced insulation or double insulation. "Added 22.106 "For cooling systems of compression type appliances using flammable refrigerants, the amount of refrigerant charged in each independent refrigeration circuit shall not exceed 150g. Compliance shall be determined by visual inspection. \m) In Chapter 23, 23.3 was added. \Note 101: The requirements for open disc springs do not apply to external conductors. \n) In Chapter 24, 24.1.2 was added.

1) IEC (International Electrotechnical Commission) is a world-wide standardization organization composed of all national Electrotechnical Committees (IEC National Committees). The purpose of IEC is to promote comprehensive cooperation among countries in the field of electrical and electronic standardization. In view of the above purposes and taking into account the needs of other activities, IEC also publishes international standards. The entire formulation work is completed by the Technical Committee. Any IEC National Committee that is particularly interested in this technical issue can participate in the formulation work. According to the agreement reached between IEC and IEC, they have a close cooperative relationship in their work: 2) IEC resolutions or agreements on technical issues are formulated by technical committees in which all national committees that are particularly interested in the issue participate, and try to express the international consensus on the issues involved. These resolutions or agreements 3) In the form of standards, technical reports or regulations for international use and in this sense recognized by national committees.
4) In order to promote international unification, IEC hopes that national committees will adopt the contents of IEC standards as their national standards to the extent permitted by national conditions. Differences between IEC and corresponding national standards or regional standards should be clearly indicated in national standards as much as possible.
5) IEC has established a non-marking procedure to express its recognition, but does not mean that a certain equipment is claimed to comply with a certain standard. 6) Some of the contents of this international standard may involve some patent rights issues, which should be noted. The IEC organization is not responsible for identifying any or all such patent rights issues. This standard was prepared by IEC Technical Committee 61C "Household Refrigeration Appliances" in the 61st "Safety of Household and Similar Electrical Appliances".
This standard constitutes the fifth edition of IEC 60335-2-24 and replaces the fourth edition of 1997, Supplement 1 (1998) and Supplement 2 (1999).
