RE: CE and/or e-mark for products operated in vehicles
As an EMC/safety third party test agency, I have performed both CE-Mark certifications and e-mark type testing of electronic devices. 95/54/EC type testing may be performed by third party test agencies, or by the manufacturer, but must be witnessed by a Notified Body. Paragraph 15.3 of the "Guidelines on the Application of Council Directive 89/336/EEC" discusses EMC for motor vehicles and devices intended for fitment into motor vehicles. Since the laptop computer, with car power supply may be operated by a passenger, while the car is being driven, 95/54/EC is mandatory. CE marking is mandatory for usage outside the automobile. Although not mandatory, I suggest testing to ISO 7627-0 to verify immunity to automotive powerline transients.

For products which are designed to be operated exclusively in vehicles like car audio equipment or car power supplies it seems to be clear that this euipment falls under the EC-Directive 95/54 and must carry the e-mark. Products which can be used in different environments, e.g. a laptop computer equipped with GPS-system, have to carry therefore the CE-mark and the e-mark and must comply to both directives (95/54 and 89/336) ?? Please give me your comment. Kind regards Andreas Thomas Product Safety Toshiba Europe
RE: CE and/or e-mark for products operated in vehicles
Andeas, I believe that we have to consider the two scenarios :- a) when the vehicle is parked and b) when it is moving. If the vehicle is parked then there should be few safety issues. If the vehicle is moving then there are an additional two scenarios :- a) the PC is operated by the driver and b) the PC operated by a passenger If the driver was operating the laptop then surely the driver would be breaking law by taking their eyes from off the road. If a passenger was operating the laptop then I reckon that the laptop should also comply with 95/54. Because it is impossible to guarantee where, when, how and by whom the laptop is likely to be used then it would seem prudent to err on the side of caution and include 95/54 but I too would be interested in any comments from the group.

RE: CE and/or e-mark for products operated in vehicles (2)
My first response on EMC-PSTC was a bit misleading! For ITE and other portable devices with cigarette lighter power adapters, 95/54/EC testing is required. However, 95/54/EC should not be listed as a directive on the Declaration of Conformity. It should be listed as a technical standard under the EMC Directive. Since 95/54/EC is not a "new approach directive" it may not be used directly for CE marking. For CE marking, the EMC Directive guidelines, para. 15.3 allows the use of 95/54/EC to demonstrate conformity with the EMC Directive. The technical requirements are within 95/54/EC, and no harmonized test specs. are listed nor required. 95/54/EC covers both vehicle EMC testing and EMC of electronic sub-assemblies (ESA). ESAs are defined as electrical or electronic devices intended to be "part of a vehicle." Therefore, portable devices with cigarette lighter power adapters are not ESAs and will not require e-marking. Therefore, for ITE with power adapters that may be used in an automobile, the declaration of conformity should list the Low Voltage and EMC Directives. Specific standards under the EMC Directive would typically be EN 55022, EN 50081-2 and 95/54/EC. Under 95/54/EC, immunity testing is not required for "ESAs whose functions are not involved in the direct control of the vehicle." Therefore, additional testing under 95/54/EC will involve only NB and BB radiated! emissions tests that may be performed either on an OATS or in an anechoic chamber. These tests may be performed in conjunction with the EN 55022 tests, limiting the additional cost impact. 1m antenna spacing is used, quasi-peak detection for the BB test, peak or average for NB. ISO 7637-1 automotive powerline transient immunity tests are recommended, but not specifically called out under the EMC Directive framework. If e-marking is required, the device is by definition either a motor vehicle or an ESA that becomes part of a motor vehicle. Conformity must be demonstrated by type testing, witnessed by a Notified Body under 95/54/EC. The Notified Body may impose other requirements such as ISO 7637-1 powerline transient testing. ESD testing is discussed in paragraph 8.4 of 95/54/EC and should not be required for either ESAs or for motor vehicles.

The problem is the appliance of the e-mark directive on products which are not intended to be fitted (permanently installed) into a car, like a laptop computer or handy. This seems to be once more a "grey area" which is not clearly defined by the people creating those directives. Have anyone of you seen comments listed up in the operating instructions of a vehicle which do not allow to operate electronic products in the car environment without observing e-mark or other specified requirements ??
