IEC 60230 PDF

Product Details IEC defines the procedure for carrying out withstand lightning and switching impulse tests and withstand superimposed impulse test on cables and their accessories. This document applies solely to the methods of carrying out the tests as such, independently of the problem of selecting the test levels to be specified. The voltages pertaining to the system on which cables and accessories are to be used are given in IEC or in the relevant product standard. This document specifies the following requirements: - the characteristics and state of the test installation and those parts of the procedure which are common to withstand tests and tests above the withstand level; - the procedure for carrying out withstand lightning, switching impulse tests and superimposed impulse test; - the procedure for carrying out tests above the withstand level which is intended for research purposes.

Terminology[ edit ] Appliance couplers enable the use of standard inlets and country-specific cord sets which allow manufacturers to produce the same appliance for many markets, where only the cord set has to be changed for a particular market.

Interconnection couplers allow a power supply from a piece of equipment or an appliance to be made available to other equipment or appliances. Couplers described under these standards have standardized current and temperature ratings.

The parts of the couplers are defined in the standard as follows. Connector: "part of the appliance coupler integral with, or intended to be attached to, one cord connected to the supply". Appliance inlet: "part of the appliance coupler integrated as a part of an appliance or incorporated as a separate part in the appliance or equipment or intended to be fixed to it".

Plug connector: "part of the interconnection coupler integral with or intended to be attached to one cord". Appliance outlet: "part of the interconnection coupler which is the part integrated or incorporated in the appliance or equipment or intended to be fixed to it and from which the supply is obtained".

Cord set: "assembly consisting of one cable or cord fitted with one non-rewirable plug and one non-rewirable connector, intended for the connection of an electrical appliance or equipment to the electrical supply". Interconnection cord set: "assembly consisting of one cable or cord fitted with one non-rewirable plug connector and one non-rewirable connector, intended for the interconnection between two electrical appliances".

Although the terms "male" and "female" are sometimes applied to these connectors, the terms are not used in the standards themselves. Gender references for connectors refer only to the contacts, not the complete connectors. Each type of coupler is identified by a standard sheet number. For appliance couplers this consists of the letter "C" followed by a number, where the standard sheet for the appliance inlet is 1 higher than the sheet for the corresponding cable connector.

Many types of coupler also have common names. Kettle plug often jug plug in Australian English is a colloquial term used for the high-temperature C16 appliance inlet and sometimes, wrongly, for the mating C15 connector. Application[ edit ] Detachable appliance couplers are used in office equipment , measuring instruments , IT environments, and medical devices , among many types of equipment for worldwide distribution.

Instead, a country-specific power supply cord can be included in the product packaging , so that model variations are minimized and factory testing is simplified.

A cord which is fitted with non-rewireable usually moulded connectors at both ends is termed a cord set. Appliance manufacturing may be simplified by mounting an appliance coupler directly on the printed circuit board. Assembly and handling of an appliance is easier if the power cord can be removed without much effort. Appliances can be used in another country easily, with a simple change of the power supply cord including a connector and a country-specific plug.

The power supply cord can be replaced easily if damaged, because it is a standardized part that can be unplugged and re-inserted. Safety hazards, maintenance expenditure and repairs are minimized. Parts of the standard[ edit ] IEC is divided into several parts: IEC General Requirements specifies two- pole and two-pole with earth couplers intended for the connection of a supply cord to electrical appliances.

This part of the standard no longer includes standard sheets which have been moved to a new part first published in IEC IEC Sewing machine couplers specifies couplers which are not interchangeable with other couplers from IEC , for use with household sewing machines. They are rated no higher than 2. This section was withdrawn in January The general requirements for these items are now included in IEC and the standard sheets are part of IEC IEC Couplers with a degree of protection higher than IPX0 [5] specifies couplers with some degree of liquid ingress protection.

IEC Couplers dependent on appliance weight for engagement. For appliance couplers the various coupler outlines are designated using a combination of letters and numbers, e. The connector supplies power to the appliance inlet. The appliance inlet is designated by the even number one greater than the number assigned to the connector, so a C1 connector mates with a C2 inlet, and a C15A mates with a C16A.

Interconnection couplers have single letter designators, e. They consist of two parts: a plug connector, which is the part integral with, or intended to be attached to, the cord, and an appliance outlet, which is the part integrated or incorporated in the appliance or equipment or intended to be fixed to it, and from which the supply is obtained.

Contents of standards[ edit ] The standards define the mechanical, electrical and thermal requirements and safety goals of power couplers.

Further sub-parts of IEC focus on special topics such as protection ratings and appliance specific requirements. Selection of a coupler depends in part on the IEC appliance classes. The shape and dimensions of appliance inlets and connectors are coordinated so that a connector with lower current rating, temperature rating, or polarization cannot be inserted into an appliance inlet that requires higher ratings. Pin temperature is measured where the pin projects from the engagement surface.

The pin temperature is determined by the design of the appliance, and its interior temperature, rather than by its ambient temperature. Typical applications with increased pin temperatures include appliances with heating coils such as ovens or electric grills. It is generally possible to use a connector with a higher rated temperature with a lower rated appliance inlet, but the keying feature of the inlet prevents use of a connector with a lower temperature rating.

Connectors are also classified according to the method of connecting the cord, either as rewirable connectors or non-rewirable connectors. In addition the standards define further general criteria such as withdrawal forces, testing procedures, the minimum number of insertion cycles, and the number of flexings of cords. IEC defines a cord set as an "assembly consisting of one cable or cord fitted with one plug and one connector, intended for the connection of an electrical appliance or equipment to the electrical supply".

It also defines an interconnection cord set as an "assembly consisting of one cable or cord fitted with one plug connector and one connector, intended for the interconnection between two electrical appliances".

In addition to the connections within the standards, as mentioned, there are possible combinations between appliance couplers and IEC interconnection couplers. Fitted with a flexible cord, the components become interconnection cords to be used for connecting appliances or for extending other interconnection cords or power supply cords.

Appliance couplers[ edit ] The dimensions and tolerances for connectors and appliance inlets are given in standard sheets, which are dimensioned drawings showing the features required for safety and interchangeability. Appliance couplers.
