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 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. This standard is also applicable to appliance couplers with auxiliary contacts rated for ac, dc or both, with a total rated current not exceeding 16A. This standard is also valid for appliance inlets/appliance outlets integrated or incorporated in appliances. 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 appliance 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 of liquid in normal use. They are classified according to whether protection against liquid spillage is provided, when installed in accordance with the manufacturer’s 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 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 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. NOTE 6: Additional auxiliary contacts can be used as part of the appliance coupler. An example of an auxiliary contact is a contact used to supply a low power device or used to transmit signals for sensors and to/from a microprocessor.
