CE Marking On Shipping Cartons
Greetings and Happy New Year to all: First let me thank everyone on the list for the help and background provided throughout 1999. I am coming near the end of launching my first Industrial CE product and having been part of this group has certainly made a hard task much easier. Today's questions is in regards to marking of shipping boxes, cartons etc. Our new product is properly CE marked on it's case. Is it necessary to show the CE mark on any of the shipping boxes or cartons? Our packaging complies with the packaging directive, but I would like to know if there are any external marking requirements that I should be aware of. Thank you in advance for your response.

Re: ESD troubleshooting
If you don't feel like constructing the probe that Ted describes, a similar one can be purchased that pushes on to the ground reference shaft. It has two tiny metal probes spaced a few millimeters apart and a few millimeters long. One of the probes is of course ground, and the other signal. These probes are used for high frequency RF measurements. I do not have access to catalogs just now, but Hewlett Packard and Tektronix would be possible sources. George Waters ICP teck...@apcc.com wrote: The first thing to do is to make sure that the oscilloscope is on a clean power source. Make sure that it is plugged into a branch circuit different from the ESD test equipment. Next, reduce the length of the ground lead. Even if you are using the shortest ground clip available with the scope, the lead will be too long. The loop area formed by the ground lead will act as an antenna. (As a test, you could place the scope probe by the test unit with the ground lead clipped to the probe tip. You will still see a significant signal on the grounded probe.) Remove the cap from the probe to expose the ground reference shaft. Take some hook-up wire and wrap a few tight turns around the ground barrel of the probe. Cut it off with enough length from the coil to solder to the board. Remove the coil and solder it to a good ground reference on the circuit board near the point that you want to measure. Take another short piece of hook-up wire and solder it to the signal that you do want to measure. Place the probe through the coil for the ground and wrap the signal wire around the probe tip. This should let you do some hands free measurement. This will keep the ground return loop as small as possible. The coaxial scope probe cable should block enough noise to prevent coupling along that path. You will still see some radiated noise getting into the probe, but you will get much more accurate measurements than you can with the standard scope probe ground leads.

I am now looking for any pointers from those more experienced than I. I have a product that is giving me some grief when indirect ESD events applied to the HCP are applied at 4kV and above. I would like to be able to view the disturbances that are present on the PCB during the event so I can try to trace down where they are coming from and judge what attempts at fixing the problem actually provide any difference. Can any of you give me some pointers or rules of thumb on how to keep the interference from the event form coupling onto a set of scope leads? I can see lots of noise but cannot definitely say that it is present on the PCB or if it is just coupling into the leads. There is noise present visible when the scope probes are left unconnected but the trace is quite different from that seen with them connected to the PCB. (but of course there is no solid reference with the probes unconnected) I need to isolate the scope leads from the test so I can actually see what is getting on to the PCB, is this actually possible??? Thanks for any comments or help. Best Regards and best wishes for the holiday season to everyone!! :-) Jeff Bailey EMC Technologist SST - A Division of Woodhead Canada Ltd.

RE: Pacemaker magnetic immunity
Ray, see Amd 1 of EN 50061 for EMC requirements for pacemakers. Section 6.3.4 addresses static fields. A PM must not be affected by 1mT. For less than 10 mT, the PM must function normally after the field is removed. Richard Woods -- From: Ray Levasseur [SMTP:ray_levass...@hotmail.com] Sent: Friday, December 24, 1999 12:23 PM To: emc-p...@majordomo.ieee.org Subject: Pacemaker magnetic immunity Hi Group, First I would like to thank everyone who responded to my earlier conducted emission problem and the valuable suggestions. I have another issue that has been brought to my attention by one of our customer reps. I have a customer that is concerned about a couple of their equipment operators that have heart pacemakers and the effects on their pacemaker by magnetic fields. Our product has some very strong dc magnets (not a magnetic field induced by current flow just bar magnets)and they are concerned about the health of these operators. I would appreciate any information I could pass on to this concerned customer. Is there a standard for pacemaker magnetic immunity such as dc magnetic strength, measured magnetic field in A/m or micro Tesla measured at a defined distance and frequency? I would like to know if our product has the potential to cause harm to people with a pacemaker. Any suggestions for testing this would be greatly appreciated. All the best for Christmas and the New Year. Ray Levasseur EMC Compliance __ Get Your Private, Free Email at http://www.hotmail.com - This message is coming from the emc-pstc discussion list.
