1 Scope
EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting
aerial bundled cables (ABC) of rated voltage U /U (U ): 0,6/1 (1,2) kV.
0 m
The objective is to provide a method of testing the suitability of accessories when used under
normal operating conditions with low voltage aerial bundled cables complying with HD 626.
This Part 6 defines the environmental tests in particular the climatic and corrosion ageing
tests. The objective of these tests is to predict the behaviour of ABC accessories when
subjected to sun radiation, to weather conditions (humidity, spraying water, heat, cold) and
pollution. EN 50483-1, EN 50483-2, EN 50483-3 and EN 50483-4 specify which type tests
included in this part of the standard are needed.
Climate differs across Europe and in order to meet the differing geographic climatic conditions
it is necessary to provide a range of tests to meet these variations. A range of optional,
additional tests is provided to meet the varying climatic needs and these should be agreed
between the customer and the supplier (see Annex C).
NOTE  This European Standard does not invalidate existing approvals of products achieved on the basis of
national standards and specifications and/or the demonstration of satisfactory service performance. However,
products approved according to such national standards or specifications cannot directly claim approval to this
European Standard. It may be possible, subject to agreement between supplier and purchaser, and/or the relevant
conformity assessment body, to demonstrate that conformity to the earlier standard can be used to claim
conformity to this standard, provided an assessment is made of any additional type testing that may need to be
carried out. Any such additional testing that is part of a sequence of testing cannot be done separately.

aerial cable consisting of a group of insulated conductors which are twisted together
including, or not, a non insulated conductor
[IEV 461-08-02, modified]
NOTE  The terms bundled conductors, bundled cables, bundled cores, conductor bundles and bundle could be
used as equivalent to the term aerial bundled cable (ABC).

3.2
aerial-insulated-cable
insulated cable designed to be suspended overhead and outdoors
[IEV 461-08-01]

type test
test required to be made before supplying a type of material covered by this standard on a
general commercial basis, in order to demonstrate satisfactory performance characteristics to
meet the intended application
NOTE  These tests are of such a nature that, after they have been made, they need not be repeated unless
changes are made to the accessory materials, design or type of manufacturing process which might change the
performance characteristics.

8 Type tests
8.1 Number of test samples and number of cycles
The number of samples and number of cycles for each of the following tests are included in
each relevant part of EN 50483.
8.2 Requirements
The requirements for the following tests shall be as given in the relevant parts of this standard.
8.3 Cleaning
On completion of the environmental tests, and between different environmental tests when
carried out as a sequence, the samples shall, unless otherwise specified, be cleaned using
running tap water for 5 min to 10 min and then by using demineralised water for the same
period. The temperature of the water shall not exceed 35 °C. The samples shall be dried
either by shaking by hand or using air blast to remove droplets of water.
8.4 Corrosion ageing tests
These tests shall be carried out when the products contain metallic parts (or parts protected
with a metallic coating), which are exposed to the atmosphere.
A justification of the tests is given in Annex A.
8.4.1 Salt mist test
8.4.1.1 Principle
This test exposes samples to a neutral salt spray (concentration of NaCl: 5 %).
8.4.1.2 Test equipment
The test equipment is defined in Clause 3 of EN 60068-2-11:1999.
8.4.1.3 Test arrangement
The preparation and use of the salt solution is defined in Clause 4 of EN 60068-2-11:1999.
8.4.1.4 Procedure
The test procedure is defined in Clause 7 of EN 60068-2-11:1999.
The connectors or accessories shall be installed as defined in the relevant parts of EN 50483.
The cycle duration prescribed, in accordance with EN 60068-2-11:1999, 7.6 shall be 7 days.
No cleaning of the samples shall be carried out between cycles.
8.4.1.5 Test reports
The test report shall include the duration of exposure and the concentration and pH of the salt
solution.
8.4.2 Gas atmosphere tests
NOTE 1  Two methods of testing are provided to meet the requirements of the gas atmosphere test. The first,
Method 1, is based on the test procedure that has been used for many years in some countries. These countries
have gained experience of both the procedures and outcomes of the test. The second, Method 2 is provided as an
alternative as it requires a less complicated test environment and is based on ASTM G85.
NOTE 2  This test may be necessary for accessories that are used in areas subjected to heavy industrial pollution.
8.4.2.1 Gas atmosphere test (Method 1)
A justification of the tests is given in Annex A.
