Twice As Nice? Not for Telecom EMC
Overlapping
regulatory requirements mean double testing, double certification,
and, therefore, double trouble for manufacturers. A recent independent
study revealed that the Automotive EMC Directive (95/54/EC)
duplicates requirements in both the EMC and R&TTE directives
for certification of radiocommunications products for use in
vehicles. In addition, the automotive directive has a more onerous
approval regime.
Conducted
by York EMC (Castleford, West Yorkshire, UK), the study was
"triggered by many questions and complaints regarding the applicability
of the [directive] to the installation of aftermarket products
in vehicles," says Olly Wheaton, chairman of ETSI's technical
committee for EMC and Radio Spectrum Matters (ERM). The report
from York also proposed improvements to address problems caused
by duplicated requirements.
As
a result of the study's findings, the European Commission's
DG Enterprise convened an ad hoc group to amend the directive.
The group includes representatives from interested member states
and selected industry associations, including the European Telecommunication
Standards Institute (ETSI). Making changes to the directive,
however, may require formal revision through the European Parliament.
Wheaton
says it is important to note that the harmonized EMC and R&TTE
standards take into account all environments, including vehicles.
Therefore, at the first ad hoc meeting, ETSI proposed that in-vehicle
radiocommunications equipment that has already been certified
and CE marked for EMC should be sufficient for having met the
EMC requirements of the Automotive EMC Directive. ETSI contends
that because radiocommunications products are not involved in
direct control of vehicle functions, repeated EMC assessment
is not justified. Moreover, the duplicated testing hinders free
access to market.
Representatives
in the commission's ad hoc group are primarily from ministries
of transport. "As a consequence, there is little support to
change Directive 95/54/EC to accept CE marked products since
these fall under the regulations of a different (i.e., telecommunications)
sector," Wheaton says.
He
points out that radiocommunications products contribute to the
electromagnetic environment, including public roads, and that
ETSI ERM considers it essential that the viewpoint of radio
and telecommunications authorities be taken into account. He
has called for the heads of national ETSI delegations to make
their concerns known to their respective ministries of transport,
and, where appropriate, to lobby at the European level.
Wheaton
rightly concludes that the objective is to achieve a regulatory
environment that considers "in a more balanced way" the needs
of all of the market players.
