The test voltage shall be taken from Table 8. It presents the UK view on standards in Europe and at the international level. B1 Initial measure- Test current: For both conductor versions, the wire jumpers shall be produced as short as possible, i. If the associated clearance, measured on the component, is less than 3 mm, the minimum groove width may be lec to one-third of this clearance. Worldwide Standards We can source any standard from anywhere in the world.
If the dimensions do not comply with the specification, the test is not met. The length of the connecting cable and conductor loops see Figures 1a, 1b and 1c is given in Table 7.
Loose parts inserted to obtain clamping of the cable are permitted if they are fixed in the connector in the assembled state. Connectors should be applied in the energy flow direction of the circuit in such way that the accessible contacts are not energized in unmated condition.
It is recommended to check the insulating material group by the PTI value. If it consists of metal, it shall meet one of the following requirements: Sulfur dioxide test with general condensation of moisture according to ISO The cable clamp can be made of insulating material or metal. Preferred values are indicated in Table 4a. This publication does not purport to include all the necessary provisions of acontract.
A7 Contact 15a Test load shall be 6.
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. Compliance is checked by a polarisation test.
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. The new set of specimens shall pass the repeated tests, otherwise the product is deemed not to comply. Connectors with breaking capacity CBCs only: Any existing protective earthing contact shall not be loaded. After the test, the samples shall show no damage impairing their further use and the entry holes for the plug contacts shall not show any serious damage.
It shall not be possible to remove the supplementary insulation without using a tool.
In the official version, for Bibliography, the following notes have to be added for the standards indicated: Click to learn more.
In this 6198, reference is made to IEC for clearance and creepage distances. Contact the Information Centre. Compliance is checked in accordance with Clause 5 of IEC All markings of 6. If terminations are provided for all types of conductors, solid, stranded and flexible, the tests shall be carried out only with flexible conductors according to Class 5 of IEC The number of operating cycles shall be specified by the DS or by the manufacturer, preferred values being given in Table 4a.
In both cases, the specimens shall be mated. The protective conductor, if any, shall be loaded with a sufficient current to perform the continuity test.

Tests – Test Xb: Electrical contact shall be maintained for no more than 4 s and no less than 2 s. Wrapped connections — General requirements, test methods and practical guidance IECSolderless connections — Part 2: The preparation and mounting of the specimen shall be as in normal use. If the product fails in only one of the tests, this test and the preceding tests which have affected the result shall be repeated on a new set of irc.
Therefore, the rated insulation voltage for a connector with creepage distances fixed by design should be reconsidered for each pollution degree separately.

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.
In the case of contact elements, a mating pair of the intended coupling elements 3. The following dates were fixed: For this test, all other contacts shall be wired in parallel. An electric device, i.
