RE: RFID tags
I agree with Frank, These tags do not have any ability to transmit. When they are within a field they dampen / load the signal from the reader. Therefore they cannot be included in the RTTE directive.

Yes. it's purely pragmatic; marking the cartons MAY persuade the customs person that he/she does not need to open the carton, scatter the packaging, lose the installation instructions and then impound the shipment on the grounds that installation instructions are not provided.

RE: RFID tags
The ones we are using have a silicon die. When the tag receives a signal it activates the die and causes a change in impedance. The Transponder detects this change and reads the difference in the reflected signal. From what I have gathered this is still considered to be passive.

RFID Demo Equipment and the FCC / Industry Canada
I have a question about use of a none certified device in the USA and Canada. We have acquired an off the shell RFID system, which has not yet gone through any certification (they will be certifying it shortly). We are integrating this into our printers. The printers will use this device to read and write information to the tags as they pass through the printer. While we are working on this we have customers who would like to start working on getting this integrated into their production systems. The FCC says that until we certify it we can not offer the product for sale or lease, etc. Could we put the following label on the product : "This device has not been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained." Then sell a development kit to the customer that included a printer with the uncertified unit in it (to a very limited number of people). Then when we are done with the certifications, swap the development printers/RFID units out for ones that are certified?

RE: CE Marking of Shipping Cartons
Strictly speaking, customs are not the enforcing authority for CE marking and should not be looking for anything, although they may act as a first line filter in some member states. The enforcing authorities in the UK, for example, are a range of government agencies including Trading Standards, Radiocommunications Agency, and Health and Safety Executive depending on which Directive is involved. It is technically feasible to import unmarked goods and for the importer to apply the marking and issue the D of C. The responsibility is that of the person placing the goods on the EU market. However, applying the marking to the shipping cartons may reduce the instances of customs opening the cartons to inspect the goods, which in turn may speed up import processing. You could also include a copy of the D of C with the shipping documentation, which might serve the same purpose. In general, I have often seen CE marked cartons in the consumer market, but less often in the industrial/commercial market. Hope this helps and clarifies. Best regards, Neil R. Barker C.Eng.

RE: CE Marking of Shipping Cartons
Richard, France stopped a product shipment because there was no CE mark. Normally, this marking would have been on the container as well as the actual product - but the label was left off by the manufacture ring folks in error. I guess I can't really tell you that having the box labeled would have prevented it - but they wouldn't have had to remove the box to inspect the equipment, and we have had to problems when the carton was marked. It's normally just part of the shipping label on the outside of the box as well as the product. Considering that this label must be printed anyway its simply the cost of the ink during printing - and the seconds to print it. There are no additional processes required so its pretty seamless. The ECO process handled the addition/removal of the CE mark on the carton at the same time it added/removed it from the product itself.

It also has limits for below 30MHz and above 1GHz. This section I understand. What I don't understand clearly is requirement R3-3 [10]. It references emissions from Class A and B unit's not exceeding Table 3-2. Table 3-2 limits are higher than the FCC Class A and B limits. The doors or covers are to be opened during emission testing. However, if the doors and covers that are not intended to be opened during EUT operation, maintenance, and/or repair need not be opened, I can still test to those higher limits. If so, I can no longer can be considered FCC A or B equipment. Is requirement R3-3 [10] mainly for central office areas and not residential? Thanks.

There are some in my company that believe the shipping cartons containing our products should be CE marked to simplify customs processing especially with the addition of the new member states in May 2004. Others feel that the marking provides no added value to the customs processing procedure. So, the question is what are the customs officials looking for in the way of CE conformity and what process will best supply that information. In particular, is there any value added in CE marking the shipping cartons?

The crucial question is how many you want. Cable manufacturers will make anything you want for big enough quantities. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
