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 (ABC) complying with HD 626.
There is variation between the different ABC specifications provided by HD 626, and tests carried out
on one of the ABC types may not be completely applicable to ABC of a different specification.
Therefore, the purchasers of accessories tested to this European Standard, must ensure that all their
requirements are met.
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.
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 in EN 50483-6).
The purpose of this Part 1 is to define the common aspects of the products included in the above
scope.

8.1.2 Without quality assurance system
These tests shall be carried out on randomly sampled items from each supplied batch according to a
standard or procedure jointly determined by the manufacturer and the purchaser.
It is assumed that these tests are representative of the whole batch.
8.1.2.1 Tests and inspection
The manufacturer or supplier shall, as a minimum, establish and maintain documented procedures for
inspection and testing activities in order to verify that the specified requirements are met. The required
inspection and testing procedures shall be provided in writing.

8.2 Final inspection and testing
The supplier shall carry out all final inspection and testing in accordance with the quality plan and/or
documented procedures to complete the evidence of conformance of the finished product to the
specified requirements.
The quality plan and/or documented procedures for final inspection and testing shall require that all
specified inspection and tests, including those specified either on receipt of product or in process,
have been carried out and that the results meet the specified requirements.
No product shall be dispatched until all activities specified in the quality plan and/or documented
procedures have been satisfactorily completed and the associated data and documentation are
available and authorized.
