Test flames — Needle-flame test method — Apparatus, confirmatory test arrangement and guidance IEC Preferred values are given in Table 4b. All markings of 6. Marking of the first contact and first row by a letter, number or another clear symbol is sufficient.

Other terminations and connection methods have to be tested in accordance with the relevant standards. This requirement does not apply to a connector in which contact identification is ensured in the end-use product.

BS EN – Connectors. Safety requirements and tests

For edge-socket connectors, the wire jumpers are soldered as close to the contact zone of the printed board as possible corresponding to the cross sectional area of the connecting cables Figure 1c.

It supersedes BS EN For numeral 3 and 4, unless otherwise specified in the detail specification or by the manufacturer, the oscillating tube, Figure 4 of IEC Compliance shall be checked by the test of 7. Your basket is empty. The length of the connecting cable and conductor loops see Figures 1a, 1b and 1c is given in Table 7.

If this is not possible, the conductor resistance shall be recalculated. After the test there shall be no damage; the cable support sleeve shall not be loosened from the body and the insulation shall show no signs of abrasion or of wear and tear.

NOTE For an unenclosed connector, the protection against electric shock is provided by the enclosure of the equipment in which the connector is mounted, in accordance with the applicable product safety standard. Safety requirements and tests Status: Comprehensive method for determining clearances and creepage distances equal to or less than 2 mm 1 IEC – Flat, quick-connect terminations – – IEC Connecting devices for low-voltage circuits EN mod for household and similar purposes – Part This requirement does not apply to connectors for example two-part connectors for printed boards and rack-and-panel connectors where mismating is prevented by their mounting provisions or by additional accessories, if necessary and available.


For two-part printed board connectors, the connection on the printed board side is made by wire jumpers corresponding to the cross sectional area of the connecting cable of the connector. The oscillating member is, by variation of distance d shown in Figure 2, so positioned that the flexible cable makes a minimum lateral movement when the oscillating member of the test apparatus is moved over its full travel. One bending is one movement, either backwards or forwards.

Maximum permissible conductor cross-sectional area used for the test shall be in accordance with the detail specification DS or manufacturer’s information.

During the test, no sustained arcing shall occur. Compliance is checked by a polarisation test. Tensile and torsion requirements shall be as specified in Table 6. Insulation piercing connections – General requirements, test methods and practical guidance 1 2 IEC – Solderless connections – EN Part 7: Particular requirements for connecting devices as separate entities with insulation-piercing clamping units IEC Connecting devices – Electrical copper EN conductors – Safety requirements for screw-type and screwless-type clamping units – Part 1: The requirement that interlock contacts will make last and break first before any other contact shall be checked.

The rate of bendings shall be 60 per minute. RevisionsInformation on standardsBritish Standards are updated by amendment or revision.

Therefore, the rated insulation voltage for a connector with creepage distances fixed by design should be reconsidered for each pollution degree separately. Any existing 6984 earthing contact shall not be loaded.


IEC System of Conformity Assessment Schemes

Particular requirements for connecting devices as separate entities with insulation-piercing clamping units IEC Contact the Information Centre. The test duration shall be 1 min.

NOTE See also 6. Marking of protective earthing contacts shall apply the symbol or PE. Various BSI electronic information services are also available which giveIt is the constant aim of BSI to improve the quality of our products anddetails on all its products and services. In case of deviation, the used factor shall be indicated uec the technical documentation.

This recommendation does not apply to connectors with breaking capacity CBC and connectors without breaking capacity COC which are so locked to each other, that they can only be disconnected by the aid of a tool or which are so mounted in an encapsulated equipment or system that the protection against electric shock is assured by the enclosure housing of the equipment or system.

An electric device, i.

If it consists of metal, it shall meet one of the following requirements: If the dimensions do not comply with the specification, the test is not met.

In no case shall the resistance exceed the maximum value given in idc. Methods of measuring clearances and creepage distances are given in 6.

In the case of contact elements, a mating pair of the intended coupling elements 3. The voltage drop between the protective earthing contact and the accessible metal part is measured after steady conditions have been established and the resistance is calculated from the current and this voltage drop.

To indicate contact, an electrical device for example a lamp shall be used. Table 2 — Compliant termination and connection methods Ref. Markings a and b of 6.
