6 Draft ETSI EN 301 489-4 V3.3.0 (2020-03)
Introduction

The structure of the ETSI EN 301 489 series has been changed for use under the RED from that used under the

R&TTED. The following text briefly explains this new format:

• The product specific part would contain in clause 7 two new tables similar to that currently in ETSI

EN 301 489-1 [1] clause 7.1 for emissions and clause 7.2 for immunity. These would inform the reader

whether the requirements, etc. are to be found in ETSI EN 301 489-1 [1] or further in the product specific part.

As an example; the assessment of a Wi-Fi router would use ETSI EN 301 489-17 [i.12] which would normatively

reference ETSI EN 301 489-1 [1] for certain aspects. Consequently:
• Changes to ETSI EN 301 489-1:
No references to product specific parts.
• Changes to product specific parts, e.g. the present document:

Two new tables, one for emissions in clause 7.1, and one for immunity in clause 7.2 that will point the reader

to the location of the requirements, i.e. ETSI EN 301 489-1 [1] or the present document.
