- 7 Classification [Go to Page]
- 7.1 Weight-engaged couplers are classified: [Go to Page]
- 7.1.1 According to whether or not protection against water spillage is provided when the connector is installed according to the manufacturer’s instructions.
- 7.1.2 According to type of equipment to be connected:
- 7.1.3 According to whether or not the coupler is intended to be engaged and disengaged with current flowing.
- 7.1.4 According to the maximum ambient working temperature of the coupler.
- 7.1.5 According to the number of cycles to be performed in the test of Clause 20. Preferred values are: [Go to Page]
- 7.1.5.1 100 000
- 7.1.5.2 60 000
- 7.1.5.3 30 000
- 7.1.5.4 20 000
- 7.1.5.5 10 000
- 7.1.5.6 6 000

- 12.1 Replacement
- 12.2 This subclause of IEC 60320-1 does not apply.
- 13 Construction
- 14 Moisture resistance [Go to Page]
- 14.2 Weight-engaged connectors which are declared as providing protection against water spillage shall be constructed so that, when installed into a representative power base, in accordance with manufacturer’s installation instructions, the connector is not affected by water.
- 15 Insulation resistance and electric strength
- 16 Forces necessary to insert and withdraw the connector [Go to Page]
- 16.1 The construction of weight-engaged appliance couplers shall be such that the connector will fully engage under the weight of the appliance or equipment, and will disengage under the weight of the power base. The minimum values of these weights shall be specified by the manufacturer’s installation instructions.
- 16.2 The minimum weight for full engagement is determined by mounting a weight-engaged connector and appliance inlet so that they may engage freely, and that the axis of engagement is vertical. A force equal to the specified minimum appliance weight, less the weight of the appliance inlet, is applied vertically downwards to the appliance inlet. The appliance inlet shall fully enter the connector, in accordance with the manufacturer’s installation instructions.
- 16.3 The minimum weight for correct disengagement of the power base shall be determined by placing the weight-engaged appliance connector on a horizontal surface so that its axis of engagement is vertical, and attaching to the connector a weight equal to the minimum weight declared by the manufacturer. The weight-engaged connector shall be free to move on the surface.

- 26.1.4 For functional insulation the values of Table 103 are applicable.
- 26.2 Appliance inlets and connectors shall be constructed so that creepage distances are not less than those appropriate for the working voltage, taking into account the material group and the pollution degree.
- 26.3 Solid insulation shall have a minimum thickness of 1 mm for supplementary insulation and 2 mm for reinforced insulation.
- 27 Resistance of insulating material to heat, fire and tracking [Go to Page]
- 27.1 Parts of non-metallic material shall be resistant to ignition and spread of fire.
- provided that the test sample was no thicker than the relevant part.
