27、ngagement 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, with a rated voltage not exceeding 250 V and a rated current not exceeding 16 A, for household and similar general purposes
28、 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 weight of the appliance to ensure correct engagement. NOTE 1 Appliance couplers complying with this standard are suitable for
29、 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 appliance coupler may exceed these figures and is to be declared by the manufacturer. It is possible that the maximum working ambien
30、t 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 of liquid innormal use. They are classified according to whether protection against liquid spillage is provided, when instal
31、led 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 be subject to spillage of liquid affecting the appliance inlet when the functioning part of the appliance or equipment is se
32、ated 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 couplers dependent on appliance weight for engagement. NOTE 5 Special constructions may be required: in locations where speci
33、al 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 clause of IEC 60320-1 applies with the following additions: IEC 60320-1, Appliance couplers for household and similar genera
