26、4:2006 4 APPLIANCE COUPLERS FOR HOUSEHOLD AND SIMILAR GENERAL PURPOSES Part 2-4: Couplers dependent on appliance weight for engagement 1 Scope This clause of IEC 60320-1 is replaced as follows: This standard is applicable to two-pole appliance couplers for a.c. only, with or without earthing contact
27、, with a rated voltage not exceeding 250 V and a rated current not exceeding 16 A, for household and similar general purposes and intended for incorporation or integration within electric appliances or other electric equipment of multi-part construction for 50 Hz or 60 Hz supply which depend on the
28、weight of the appliance to ensure correct engagement. NOTE 1 Appliance couplers complying with this standard are suitable for use in appliances which are used in an ambient temperature not normally exceeding 25 C but occasionally reaching 35 C. However the ambient temperature surrounding the applian
29、ce coupler may exceed these figures and is to be declared by the manufacturer. It is possible that the maximum working ambient temperature for the appliance inlet and for the connector may be different. NOTE 2 Appliance couplers dependent on appliance weight for engagement may be subject to spillage
30、 of liquid in normal use. They are classified according to whether protection against water spillage is provided, when installed in accordance with the manufacturers installation instructions. NOTE 3 If appliance inlets according to this standard are used with appliances or other equipment which may
31、 be subject to spillage of liquid affecting the appliance inlet when the functioning part of the appliance or equipment is seated on its power base, then protection against moisture is to be provided by the equipment. NOTE 4 References to standard sheets within IEC 60320-1 do not apply to appliance
32、couplers dependent on appliance weight for engagement. NOTE 5 Special constructions may be required: in locations where special conditions may prevail, for example, in ships, vehicles and the like; in hazardous locations, for example, where explosions are likely to occur. 2 Normative references This

45、ation instructions of the manufacturer; they are tested with a.c. at 50 Hz or 60 Hz. Non-rewirable weight-engaged connectors shall be submitted with a cord at least 1 m long. For those clauses requiring the tests to be carried out on weight-engaged connectors and appliance inlets installed in accord
46、ance with the manufacturers instructions, representative appliances or appliance parts shall be supplied. 5.5 Replacement: For weight-engaged appliance inlets three specimens are required, to be subjected to the tests specified. For weight-engaged connectors six specimens are required: set 1 of thre
47、e specimens is subjected to the tests specified, with the exception of those of Clauses 14, 15, 16, 19, 20 and 21, and of 24.2; set 2 of three specimens is subjected to the tests of 14.1 and of Clauses 15, 16, 19, 20 and 21 (including the repetition of Clause 16). For weight-engaged connectors which
48、 are declared as providing protection against water spillage, three additional specimens are required, which are subjected to the test of 14.2. For weight-engaged connectors of elastomeric or thermoplastic material, two additional specimens are required which are subjected to the tests of 24.2.1 or
49、24.2.2, whichever is applicable. For non rewirable weight-engaged connectors with indicators, three additional specimens with one pole of the indicator disconnected are required for the tests of Clause 15.
