Re: [PSES] Lists Of Harmonised Standards
Hello, I'll start by saying I don't know when the next version of the Official Journal (harmonised standards) for the EMC and R%TTE Directives is due out. For the EMC and RTTE Directives, the last release was 23 October 2012, so I would expect to see a new version released soon. (Within 2013, I would assume, but that's a guess) As for the proposed Radio Equipment Directive (to replace the RTTE Directive), the 'proposed' timeline is: RE-D draft text was proposed on 17 October 2012. EU Parliament discussions from Q1 of 2013. Discussions estimated to take approximately 1 year. Final text expected in Q1 of 2014. Transition period of 18 months expected, so the old RTTE approach should finally be replaced by the end of 2015. Of course, that was just the plan. When do things ever really happen early, or even on time? J I suspect that schedule has already slipped. Michael.

Re: [PSES] Verification under FCC rules and our Digital Class A product for industrial use only
Hello all, I agree with Tom that it only applies to Class B computer peripherals. However, I thought I'd share an interesting recent experience with you, for your information. I sent a KDB to the FCC about a boat (luxury yacht) that had a USB port on the dashboard (I'm not sure if boat users employ the terminology 'dashboard'? I guess I mean the place where the 'driver' stands, to guide the 'pointy end' of the boat). J The USB port on the dashboard was there to allow a person to use a laptop, to update the software to the boat's GPS and navigation systems. The FCC confirmed that the GPS etc. within the boat's dashboard would require a DoC, because it becomes a Class B computer peripheral when you take a laptop onto the boat and plug it into the dashboard. I suspect this probably comes from the history of the Class B or A decision, with regard to proximity to television receivers. Being a luxury yacht, it had many television receivers.

Re: [PSES] Ground Plane Grounding in the Immunity Lab
Grace: Welding galvanized steel is not a good idea; toxic zinc fumes. What is a building collar? Your immunity lab must be within a shielded enclosure, so it should already be safety grounded. Since you will be doing ESD testing INSIDE the enclosure, you will not have to be draining any charges of the exterior of that chamber.

Re: [PSES] Verification under FCC rules and our Digital Class A product for industrial use only
Brian: I should let some other ex-FCC guys comment on this authoritatively, but I can toss in my observations too. There is a voluntary EMC standard for vehicles in the USA, but RV's are built with a split responsibility. A chassis maker (like Ford or Freightliner of Mercedes) builds a chassis (likely under the EMC standard) and then sells it to an RV coach builder (who either hasn't heard of the standard or ignores it). Yachts are a bit different; I think that there is a body (NMEA, National Marine Electronics Association ?) that sets some standard for the marine environment, but they seem to be focused on data interoperability more than traditional EMC. Another interesting angle is that RV's and yachts are rather expensive, so the people who own them tend to have a bit more personal resources available to mitigate their own EMC problems. And lastly, if the FCC doesn't hear complaints, then they probably have enough obligations already and likely wouldn't want to extend into larger areas of responsibility. Maybe. Anyway, God doesn't like trailer parks, as he always routes His tornados through them.

If mechanical strength is also required, thick sheet of galvanized steel or stainless steel may be used. Galvanized steel is cheap, but, personally, I don't like this kind of plated material as we may need to take care so that those thin plating will not be damaged. Recently, we replaced galvanized steel sheets in our old shielded rooms with austenite stainless steel sheets. If mechanical strength is not important, thin sheet of aluminum or copper may work well. In the case of IEC 61000-4-2, minimum thickness of the ground plane is 0.25 mm for copper and aluminum. Copper is electrically good but its surface may not looks so good, and can be heavy and expensive than aluminum. When weldering the metal sheet, is there anything that need to be cautious? It can become troublesome to weld thick metal sheets placed on the floor, and some material may not suitable for welding. I rather like not to weld and bond them with other means.

Re: [PSES] Ground Plane Grounding in the Immunity Lab
Grace, Our lab is used for testing of ITE products to the IEC 55024 (CISPR24) immunity standard. We built ours from sheets of 1/4 (6mm) 5052 aluminum, screwed down onto 1 (25mm) plywood, with the plywood then fastened to the building floor. (Our products are large, heavy, rack-based systems, and this aluminum is hard enough to prevent the rack casters from doing any damage to the plate.) A 4 (10cm) wide backing plate is placed under each butt joint, and fasted to the plates with countersunk screws about every 4 along the joint. This insures good electrical continuity across the entire plane. The backing plate does require the plywood to be routed/notched at the butt joints, to accommodate the extra thickness of the backing plate. We have two such floors, one which is about 15 years old, and have had no issues with them (electrical, mechanical, auditors). These are grounded to the building steel. One uses a flat braid, the other uses 6 gauge wire. John D.

Re: [PSES] Obscure requirement
Dare we think that it's the Finsbury Local Plan: Statement of legal compliance [Document reference: FLP39] See http://www.islington.gov.uk/publicrecords/library/Planning-and-building-cont rol/Publicity/Public-consultation/2012-2013/(2012-10-23)-Response-to-Inspect or's-legal-compliance-questions-dated-17-Oct-2012.pdf And then, FLP is the Front Locating Point, used in underground positioning with an RF signal. But there's a legal definition; a Family Limited Partnership. Maybe some more details might help. :) Ed Price WB6WSN Chula Vista, CA USA -Original Message- From: Pete Perkins [mailto:peperkin...@cs.com] Sent: Friday, August 23, 2013 4:53 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] Obscure requirement Psnet, I've been asked about FLP39 compliance for equipment.
