2 Modifications to the Introduction
Delete the text and replace with:
“This document provides the general part of series EN 50525. The individual product standard parts in
Annex-E are for equipment manufacturers, installers and end-users.
The use of these cable standards in a different way than that recommended by EN 50565-1 and
EN 50565-2 could result in a lowering of safety and/or in a reduction of the expected life of the cable.
For the relationship with EU Directive (2014/35/EU) see informative Annex ZZ of the individual parts.
This part contains only the general requirements. Each separate product standard part refers to this
part.
In some countries local regulation(s) may define reaction of fire performances if the product is for
permanent installation in works. Performance requirements are those given in EN 50575 for relevant
properties.”
3 Modifications to the Scope
In the second line, delete “a.c.” and replace it with “AC”
