This chapter in the scope GB 4706.1-2005 is replaced by the following: This standard specifies the special safety requirements for electric commercial refrigeration appliances that are self portable compressors or assembled from two units into separate appliances (split systems) according to the manufacturer's instructions. Note 101: Examples of commercial refrigeration appliances within the scope of application of this standard are as follows: - Refrigeration display cabinets and refrigeration storage cabinets; -—— Mobile trolley type freezer; - He assisted counter cabinets and self-service counter cabinets—— Forced air cooling equipment and forced air freezing equipment. In practical terms, this standard covers the common hazards that arise from these commercial refrigeration appliances. This standard does not cover the structural characteristics and working characteristics of refrigeration appliances regulated by ISO standards. Note 102. The following facts should be noted: - For equipment intended for use on vehicles, ships, or aircraft, additional requirements may be required—— In many countries, national healthcare departments, national labor protection departments, national water supply management departments, national traffic management departments, and similar departments have set additional requirements for appliances. Note 103: This standard is not applicable to: - Household refrigeration appliances (GB 4706.13/IEC60335-2-24); - Industrial refrigeration systems; - Electric motors compressors (GB 4706.17/IEC60335-2-34)—— Commercial vending machines (GB 4706.72/IEC 60335-2-75)—— Commercial ice cream machine—— Commercial ice makers—— Cold storage—— Multiple cold rooms using the same remote compressor. Note 104: This standard does not apply to appliances that charge more than 150 g of combustible refrigerant in each independent refrigerant circuit. For the safety evaluation and installation procedures of such devices, ISO 5149 can be referred to. Due to the above reasons, the safety evaluation of such devices cannot be carried out according to this standard. 2 Normative References: The clauses in the following documents become clauses of this standard through reference in this standard. For dated reference documents, all subsequent amendments (excluding corrected content) or revisions are not applicable to this standard. However, parties to agreements based on this standard are encouraged to study whether the latest versions of these documents can be used. For undated references, the latest version applies to this standard. This chapter of GB 4706.1-2005 applies except for the following content. The following content is added to this article: GB 4706.17 Safety of Household and Similar Electrical Appliances, Special Requirements for Electric Motors and Compressors (GB 4706.17-2004, IEC 60335-2-34:1999, IDT).
