60335-2-104 IEC:2004 – 13 – HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – SAFETY – Part 2-104: Particular requirements for appliances to recover and/or recycle refrigerant from air conditioning and refrigeration equipment 1 Scope This clause of Part 1 is replaced by the following: This International Standard deals with the safety of electrical appliances to recover and/or recycle refrigerant from air conditioning and refrigeration equipment incorporating open drive or motor-compressor s, their maximum rated voltages being not more than 250 V for single phase appliances and 600 V for all other appliances. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by service personnel in shops, in light industry and on farms, are within the scope of this standard. The appliances referenced above may consist of one or more factory made assemblies. If provided in more than one assembly, the separate assemblies are to be used together, and the requirements are based on the use of matched assemblies. NOTE 101 A definition of “sealed motor-compressor ” is given in IEC 60335-2-34. NOTE 102 Requirements for refrigeration safety are covered by ISO 5149. NOTE 103 For appliances using flammable refrigerants, additional requirements are under consideration. NOTE 104 Attention is drawn to the fact that for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary; for appliances subjected to pressure, additional requirements may be necessary; in many countries additional requirements are specified by the national he
