26 prEN 50483-4:2024 includes the following significant technical changes with respect to EN 50483-4:2009:
27 This is Part 4 of CENELEC standard EN 50483 “Test requirements for low voltage aerial bundled cable
28 accessories”, which has six parts:
29 — Part 1: Generalities;
30 — Part 2: Tension and suspension clamps, fittings and brackets for self supporting system;
31 — Part 3: Tension and suspension clamps for neutral messenger system;
32 — Part 4: Connectors;
33 — Part 5: Electrical ageing test;
34 — Part 6: Environmental testing.
35 Introduction
36 The objective of the EN 50483 series is to provide a method of testing the suitability of accessories when used
37 under normal operating conditions with low voltage aerial bundled cables (ABC) complying with HD 626.
38 This European Standard does not invalidate existing approvals of products achieved on the basis of national
39 standards and specifications and/or the demonstration of satisfactory service performance. However, products
40 approved according to such national standards or specifications cannot directly claim approval to this
41 European Standard. It may be possible, subject to agreement between the customer and the manufacturer
42 and/or the supplier, and/or the relevant conformity assessment body, to demonstrate that conformity to the
43 earlier standard can be used to claim conformity to this standard, provided an assessment is made of any
44 additional type testing that may need to be carried out. Any such additional testing that is part of a sequence
45 of testing cannot be done separately.
46 1 Scope
47 EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled
