For dated references, only the edition cited applies. In this case, reference is made to IEC for clearance and creepage distances. If protection is claimed by the manufacturer, the requirements of 6. The new set of specimens shall pass the repeated tests, otherwise the product is deemed not to comply.
If the dimensions do not comply with the specification, the test is not met.

Preferred values are indicated in Table 4a. Broken strands shall not pierce the insulation. One bending is one movement, either backwards or forwards. Symbols are given in 61948 NOTE The pollution degree strongly influences the rated insulation voltage of a connector.
If it consists of metal, it shall meet one of the following requirements: A current equal to the rated current of the connector is passed through the conductors, the voltage between them being iev rated voltage.
The test shall be carried out according to test 9a of IECunder the following conditions, unless otherwise specified. After the test there shall be no damage; the cable support sleeve shall not idc loosened from the body and the insulation shall show no signs of abrasion or of wear and tear.

For the relationship between creepage distance and clearances see 5. Contact the Information Centre. This website is best viewed with browser version of up to Microsoft Internet Explorer 69184 or Firefox 3. This lower pollution degree also ifc to mated connectors where the enclosure is ensured by the connector housing and which may only be disengaged for test and maintenance purposes.
If this is not possible, the conductor resistance shall be recalculated. The requirement that interlock contacts will make last and break first before any other contact shall be checked.
The test duration shall be four days. Take the smart route to manage medical device compliance.
The test shall be carried out according to test 5a of IECunless otherwise specified, under the following test conditions. This standard does not apply to connectors in or on equipment where application specific safety requirements for connectors exist.
Ief requirements for connecting devices as separate entities with insulation-piercing clamping units IEC NOTE If pilot contacts last make, first break contacts are used for the electrical interlock, these can be 6184 when disengaged if the pilot contacts are protected against indirect contact with live parts. If the testing has to be made on free contacts e. The faster, easier way to work with standards. A7 Contact 15a Test load shall be 6. You may experience issues viewing this site in Internet Explorer 9, 10 or Flat, quick-connect terminations, which are definitely not designed according to IEC can be used if the test program according to IEC is met.
BS EN 61984:2009
Creepage and clearance distances are not taken into consideration for the test. For a connector with a degree of protection IP54 or higher according to IECthe insulating parts inside ief enclosure may be dimensioned for a lower pollution degree.
Any existing PE contact is not involved in the test. Marking of the first contact and first row by a letter, number or another clear symbol is sufficient.
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 ieec. Connectors with breaking capacity CBCs only: For each test group, a separate set of new specimens shall be used. During the test, no sustained 6198 shall occur. If this cannot be granted by the design or manufacturing process itself, the in-process test schedule according iiec 7.
All markings of 6. Therefore, the rated insulation voltage for a connector with creepage distances fixed by design should be reconsidered for each pollution degree separately. Maximum three contacts per specimen plus protective earthing contact, if any. C1 Temperature 5a 7. Principles, requirements and tests IEC The rate of bendings shall be 60 per minute.
The test position shall be horizontal or, if not possible, as in normal use. The cable clamp can be made of insulating material or metal.

Dimensions shall comply with the DS or manufacturer’s specification A2 Durability of 7. Alternatively, the specified r. A force of 5N shall be applied 661984 a duration of 10 cycles. Marking of protective earthing contacts shall apply the symbol or PE.
