The specimen is fixed to the oscillating member of the apparatus so that, when this is at the midpoint of its travel, the axis of the flexible cable, where it enters the specimen, is vertical and passes through the axis of oscillation.

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: On the basis of the tests according to IEC or IEC of Table 3, insulation piercing connections are excluded from the above requirement.
This requirement is not necessary for non rewirable connectors. A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions. Symbols are given in IEC Compliance is checked by a polarisation test. The length of the connecting cable and conductor loops see Figures 1a, 1b and 1c is given in Table 7.
For double insulation, where basic and supplementary insulation cannot be tested separately, the insulation system shall be considered as reinforced insulation. You may experience issues viewing this site in Internet Explorer 9, 10 or Compliance shall be checked by the test of 7.
A7 Contact 15a Test load shall be 6. This requirement does not apply to a connector in which protection against electric shock is ensured by its mounting provisions or by the use of safety extra-low voltage SELV, according to IEC in the end-use product. Compliance is checked in accordance with Clause 5 of IEC Electrical and thermal tests on terminations shall be carried out in conjunction with the test on the connector.

If these conditions are met, connectors are considered as enclosed even if the pins are accessible in unmated condition and, in mated condition, all active parts are protected against indirect contact. Kec test duration shall be four days.
General requirements and 22particular requirements for clamping units for conductors from 0,2 mm ic to 35 mm included IEC Marking of the first contact and first iex by a letter, number or another clear symbol is sufficient.
Electrical contact shall be maintained for no more than 4 s and no less than 2 s. Compliance is checked according to IEC Press-in connections — General requirements, test methods and practical guidance IECSolderless connections — Part 6: At the conductors, as close as possible to the termination.
A list of organizations represented on this ic can be obtained onrequest to its secretary. The number of operating cycles shall be specified by the DS or by the manufacturer, preferred values being given in Table 4a.
