ESAs certification to 95/54/EC

2002-06-24 Thread Fang Han

Hi Colleagues,

It looks like all products for vehicle application, even they have been 
certified to EMC Directive or R&TTE Directive, must be certified to 
95/54/EC (vehicle EMC directive) before Oct 1, 2002.  It seems to me that 
the certification route for vehicle EMC directive is different with EMC 
directive or RTTE directive certification.   I am looking for an accredited 
lab/body that is authorized to certify ESAs products to 95/54/EC.  I wonder 
if all these labs/bodies are located in Europe or there are some in USA.  I 
understand that these labs/bodies should be authorized by the Ministry of 
Transportation of a EU member state.  A certification done by such a lab 
will be accepted by all other EU member states.


I appreciate it very much if someone familiar with this can shed some light.

Thanks a lot,

Fang

EIRP=D^^2*E^^2/30
ERP=EIRP/1.64

The maximum effective radiated power of the TUTT integrating CMM 8600 modem
module is calculated using the following equations

where E is measured maximum electric field strength, 
D is the distance of 3 meters between the EUT and measurement antenna.
