EN 3475‑701:2026 includes the following significant technical changes with respect to EN 3475‑701:2017:

editorial revision;
in subclause 4.2: specification that the specimen shall be taken from the finished cable for insulation stripping;
in subclause 4.3.1: specification that the specimen shall be taken from individual wire before integration in a finished cable for adherence of insulation to the conductor.

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this document: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United Kingdom.

1 Scope

This document specifies methods of measuring the strippability and adherence of the insulation to a conductor of a finished cable.

When a particular method is not specified in the detail product specification, method A is the default test method.

Method B is suitable for wires insulated with materials showing a low adhesion to the conductor due to the poor repeatability of the test method A with this type of wires.

This document is intended to be used together with EN 3475‑100.
