The EU directives introduce the concepts of a “cognizant body”, a “notification
body”, and a “construction file”. Cognizant bodies are simply technical experts
recognized by the EU committees to review technical regulations and
compliance. Any acceptable test lab will have a preferred cognizant body for
their certifications. Each regulatory body will have at least one engineer
designated as the notification body for that country, and he receives any
communication about certification or changes to a certified system. While this
may seem confusing, it does avoid the legal problems of engineering titles and
varied bureaucratic ministry names.
Construction files (CF) are a common format for presenting pictures, schematics,
and all other information on the parts and processes used to actually build a
certified system. The report of antenna range measurements will be included in
the CF. Your cognizant body will review the construction file before granting the
authorizations for CE mark and EU identification label on your system.
The first problem in the EU is usually Border Customs, who have been trained to
look for the CE logo marking for all products. You may need special forms or
permits to simply ship pre-production models to your test lab. The Internet web
site “www.etsi.co.fr” has information for ordering the full EU marketing
regulations.
Certification Testing - The emissions are measured in a calibrated environment
defined by the regulations. USA and Canada use an “open field” range with 3
meters between the device under test (DUT) and the antenna. The range is
calibrated by measurement of known signal sources to generate range
attenuation (correction) curves in accordance with ANSI C63.4-1992.
