RE: Don'r Get Caught Running a Red Traffic Light!
This thread has digressed quite a bit... Allow me to add to it! 3M makes something called the Opticom System. It is a traffic management device that really helps emergency vehicles make their way thru heavy traffic... Here's an article that summarizes it nicely: http://www.pilotonline.com/news/nw0111roa.html Also, there is a well produced video under the 3M Opticom System section here: http://www.3m.com/us/safety/tcm/products/itsvids.jhtml Paul Hare e: ph...@pirus.com Compliance Engineer w: 978.206.9179 Pirus Networks f: 978.206.9199 43 Nagog Park c: 508.450.0376 Acton, MA 01720 i: www.pirus.com -Original Message- From: Doug McKean [mailto:dmck...@corp.auspex.com] Sent: Friday, March 08, 2002 8:38 AM To: ieee pstc list Subject: Re: Don'r Get Caught Running a Red Traffic Light! Just as a side issue about remote monitoring of red-light runners ... One unintended consequence of cameras watching for people who run lights happened in Fremont about 2 years ago. A couple of stop lights were set up with cameras as an experiment. During the course of rush hour traffic one day at one of the experimental camera sites, an emergency vehicle was stuck behind several vehicles sitting for a red light. Apparently the fire truck was boxed in since the roads were several lanes wide and the truck was all the way over in a right lane. Lights and siren were blaring away. Q: Did any of the cars move out of the way of the fire truck and in doing so some would have to move through the intersection and thus thru the red light? A: No. Reason: No one wanted to get a ticket running the red light. Be rather ironic that the fire truck was responding to the home of someone sitting at that intersection. Just something to think about. Regards, Doug McKean --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

RE: EFT Failures..Update!
Alex, make sure you investigate whether or not energy is coupling to other cables of the EUT and causing problems. In other words, try to reduce the system (remove cables) and see if the EFT failures persist. If you can't remove a cable due to functionality, place ferrites on it instead (near the EUT). You may be surprised how a failure manifests itself. Sometimes you've got to back up and take a look at the forest... :) Good luck...

RE: FCC rule interpretation (add'l info)
Stuart, As a side note, I've seen an FCC application where the second harmonic of the device was measured and reported to be at the limit (i.e. 54 dBuV/m). Since the second harmonic was the closest to the limit, the transmitter's power had been increased to a point at which there was zero margin (questionable philosophy considering manufacturing variabilities, I know). The limit is the limit, right?? Unfortunately, 54 dBuV/m is technically greater than 500 uV/m and the FCC wouldn't certify the device. I only make these comments since you have been using 54 and 74 dB in your postings...

Answer is no(IMO). If the idea is to be able to take peak measurements instead of average measurements to expedite the test, then I suggest you take your peak measurements and compare them to average limits. If the peak measurement meets both the calculated peak limit(5000 uv/m) and the stated average limit(500uv/m), then there is no need to make the average measurement. If, however, the peak measurement meets only the peak limit, you are still obligated to take an average measurement and compare it to the average limit. The stated limit always takes precedence over any derived limits. ~ Sam Wismer Lead Regulatory Engineer/ Radio Approvals Engineer LXE, Inc.

RE: EN61558 60742
Brian, As of August 1, 2001, EN 60742:1995 should not be used for presumption of conformity to the LVD. EN61558-2-6:1997 supercedes it. The last date of mfr is unimportant. The date which the xfrmrs are placed on the market determines which standards to use in order to demonstrate compliance. Although a device may be built before the date of cessation of superceded standard, it still must comply with the newer standard if that date has passed. Generally speaking, there is a three to four year window between when the new standard is announced in the Official Journal of the European Communities, and when it becomes required. Usually that is a long enough period of time to allow industry to comply with the new standards.

Detachable AC Cordset Selection for the EU
Hello group, I am in the process of specifying detachable AC cordsets for European distribution of my product. It uses an autoranging power supply (100-240VAC) and is rated for 12 A max with a C14 appliance coupler. I initially thought this would be a trivial task of matching plug and connector variations for each of the EU countries and specifying a 12 A cord. However, it looks like all the cordsets that are generally available with European connectors are rated for 10 A max. I am also lead to believe that the C14 coupler is rated for 15A in North America, but only 10 amps in Europe. Are electrons hotter on the east side of the pond?? Amongst my circle of compliance peers, there seems to be a difference of opinion as to what current rating the cordset should have. I would think that the current rating of any cordset I choose for Europe would need to be rated for 12A (Better safe than sorry, right?). But half of the people I've talked to say, But why? The current will be about half of the 12A max, or 6 amps, due to the higher line voltage. And after all, the mains voltage should be within 10% of nominal!! Therefore a 10A cordset is plenty good! If I had my way, I would special order a 12A cordset (And I guess this would change my appliance coupler?). But, it would be nice if I could buy an off-the-shelf 10A cordset because of pricing and availability issues. Any comments?

Author: cfil...@sears.com at INTERNET List-Post: emc-pstc@listserv.ieee.org Date:3/19/2001 7:44 AM PLEASE READ THE FOLLOWING WARNING FROM IRV LEVINSON: I received a telephone call last evening from an individual identifying himself as an 'ATT Service Technician' who was conducting a test on telephone lines. He stated that to complete the test I should touch nine(9), zero (0), pound (#), and then hang up. Luckily, I was suspicious and refused. Upon contacting the telephone company, I was informed that by pushing 90#, you give the requesting individual full access to your telephone line, which enables them to place long distance calls billed to your home phone number. I was further informed that this scam has been originating from many local jails/prisons. I have also verified this information with UCB Telecom, Pacific Bell, MCI, Bell Atlantic and GTE. Please beware. DO NOT press 9 0 # for ANYONE. The GTE Security Department requested that I share this information with EVERYONE I KNOW. PLEASE pass this on to everyone YOU know. If you have mailing lists and/or newsletters from organizations you are connected with, I encourage you to pass on this information to them, too. After checking with Verizon, they said it was true so do not dial nine (9), zero (0), pound (#) and hang up for anyone! --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Cable Harnesses and Product Safety (UL1950/CSA C22.2 no. 950)
I use an outside vendor to assemble various cable harnesses for my products. The vendor is recognized by UL and CSA and undergoes quarterly audits. I supply a drawing that specifies certain components (e.g. Connector X, Line Filter Y). However, I leave it up to them to use whatever UL/CSA recognized wire and shrink tube they have laying around. (I indicate the color, gauge, etc., but not the manufacturer or part number.) When my product safety evaluation is performed, what documentation do I need to satisfy the UL/CSA engineer regarding the wire and shrink tube? Comments are appreciated.
