R&TTE directive
Can anyone state any detailed examples where a proper product test suite under the R&TTE directive could not be found in the harmonized standards (TCF route for conformity)?

RE: Varient Model on Fcc.
For a listed product, is a multiple listing not required? It certainly is here in Canada. Remember, the trend at the FCC is to ensure that the FCC ID matches or is linked to the company placing the product on the market. The other question to be asked is, is the product truly identical, or is there a physical difference between the OEM version and the original? If there is a difference, then it may indeed be necessary to complete a new submission. This is particularly true for intentional radiators (including integration of modules, re-packaging/antenna changes, etc). Of course, if we are dealing with IT equipment under SDOC then all listing stuff does not matter that much... Regards, Kate Kathy M.

RE: HiPot testing of DC mains powered products
Hi David, It's good to hear from someone who has spent a couple of second shifts out in the cold 10m test site with me. Hope all is going well. Your answer would be a possibility for "self-certification" cases. However, if we want to use an NRTL mark such as UL, TUV, CSA ...; then the agency will dictate whether or not to hipot. My understanding is that such agencies will require hipot on products even if they are rated 48VDC (which may be considered SELV) as long as the products use more than a minimum power level. My understanding is that the power level is around 15Watts. I believe that the reasoning behind this has more to do with fire safety than shock safety. Any product that draws more than a certain power level (again I think that about 15 Watts is the cutoff) from a DC mains (i.e. station battery ...) is considered a definite power/energy/fire hazard...thus the hipot requirements. Just a little background...I assume that the test report for this product will specify the testing required; but I wanted to get a feel for what others were doing or would do in the same situation.

Re: HiPot testing of DC mains powered products
Chris, Greetings! You may not even need to perform production line hipot if the unit is a fiber only product. Since the mains are SELV (unless you are shipping to certain Euro Telco's) the only time you should need production line hipot is if you have wired (TNV-2 or TNV-3) interfaces, assuming no other connections to hazardous circuits. Granted my advice may be flawed as I am used to permanently connected, stationary, restricted access location products that are a far cry from portable equipment as far as safety standards go.

Re: HiPot testing of DC mains powered products
Chris, The reason that I agree with John that you should be testing both is that the custom DC cable that you are assembling and shipping with your product can have marginal or failed insulation that the hi-pot test would catch. Such potential failures can have spectacular results at your customers' installation. Consider that every UL Listed/CSA Certified (ac) cordset is 100% hi-pot tested at the manufacturing location, for very good reasons. You should do no less. taniagr...@msn.com - Original Message - From: John Juhasz Sent: Tuesday, November 06, 2001 10:15 AM To: 'Chris Maxwell'; EMC-PSTC Internet Forum Subject: RE: HiPot testing of DC mains powered products If you conduct the functional tests of the chassis with the DC cable that ships with it, then it's not much of a hassle and you know that the whole package is fine.

I have a 48VDC powered product which will be hipot and ground continuity tested off of the production line in order to maintain agency certification. The product uses D-shaped three pin power connector. (Same size as a DB15, but has three large power pins instead of 15 signal pins). When we sell the unit, we pack it with an accessory kit which includes a 15' cable assembly terminated with the mate to the product's power connector. So, essentially, we sell the unit with a "DC mains" cable that we make. Now, where should the hipot test be performed? Should I make a test cable assembly for the hipot/ground bond tester which is terminated with the proper connector so that the tester can plug directly into the chassis? This would essentially test the chassis only. (because we would use this same test cable for every unit) Or Should I take each unit and connect the DC mains cable to be shipped with it, then apply the hipot/ground bond probes to the other end of the DC mains cable? This would test the entire system including the chassis and the cable. In my mind, this question comes up because we are making a custom mains cable for this DC product. It is different than AC products; because, with AC products, we can test the chassis by itself and assume that the mains cable is OK because we buy mains cables that have been previously hipot/ground bond tested by their manufacturers.

If you merely insert the cable during packing for shipment, consider doing a hi-pot on the cable itself on it's production line. Personally, I would prefer to test both, whether it was together or not. John Juhasz Fiber Options Bohemia, NY -Original Message- From: Chris Maxwell [mailto:chris.maxw...@nettest.com] Sent: Tuesday, November 06, 2001 10:36 AM To: EMC-PSTC Internet Forum Subject: HiPot testing of DC mains powered products Hi all, I have a question. I have a 48VDC powered product which will be hipot and ground continuity tested off of the production line in order to maintain agency certification. The product uses D-shaped three pin power connector. (Same size as a DB15, but has three large power pins instead of 15 signal pins). When we sell the unit, we pack it with an accessory kit which includes a 15' cable assembly terminated with the mate to the product's power connector. So, essentially, we sell the unit with a "DC mains" cable that we make. Now, where should the hipot test be performed? Should I make a test cable assembly for the hipot/ground bond tester which is terminated with the proper connector so that the tester can plug directly into the chassis? This would essentially test the chassis only. (because we would use this same test cable for every unit) Or Should I take each unit and connect the DC mains cable to be shipped with it, then apply the hipot/ground bond probes to the other end of the DC mains cable? This would test the entire system including the chassis and the cable. In my mind, this question comes up because we are making a custom mains cable for this DC product. It is different than AC products; because, with AC products, we can test the chassis by itself and assume that the mains cable is OK because we buy mains cables that have been previously hipot/ground bond tested by their manufacturers.

RE: Varient Model on Fcc.
Tommy, I'm not exactly sure what you're asking. If you're asking if a Product which is labeled as Class A can be relabeled as a Class B product because they look the same, the answer is no. The product must be properly retested to assure its compliance with the Class B limits and then you must have a test report approved by the FCC. I have little doubt that if the two really were the same they would be labeled differently. Secondly, the FCC ID is a means of identifying the manufacturer. Therefore, unless your company is the holder of the FCC ID in question, I suggest you ask the printer manufacturer the question you're posing to the group.

RE: "Safety Critical" etc - the future
An industry specific guideline (SEMI S2, developed for the semiconductor manufacturing industry) that I spend a lot of time with has cautions against "hazardous power", defined as 240VA or greater regardless of the potential. In the same industry, fire risk is a very muddy topic to sort out. In a chip fab, even the smallest amount of smoke can cause thousands of dollars damage in an ultra-clean-room. It's often difficult to get people to sort out a fire that can destroy a building from one that can credibly cause significant harm to personnel. Although fire can cause immense amounts of damage, *generally speaking*, people rather successfully avoid it unless thier egress is impeded. It seems that to truely define the potential risk of most fires, one must understand a general model of the enviroment in which they will occur. It is very difficult to frame such a general model (with consensus acceptance) with a product sitting on a test bench. There are certainly some fires that are particularly threatening to personnel, such as colorless hydrogen fires. Most fires, however, are self-revealing. Of course one must appropriately consider explosions that may precede or follow a fire. -Lauren Crane -Original Message- From: Allen, John To: emc-p...@majordomo.ieee.org Sent: 11/6/2001 4:10 AM Subject: RE: "Safety Critical" etc - the future Hi Folks I agree with John W - and a single fire can (and does!) kill and injure FAR more people than a single electric shock.

Not to mention Lithium Batteries. An "A" sized LiSo2 cell can still deliver more than 90 (NINETY) Amps After being short circuited for 15 minutes. Lithiums can also explode - which is why it take many hours to verity and test the charging and ANTI-charging circuits in some products.

Re: "Safety Critical" etc - the future
I think this gets back to what John W originally stated. A safety critical component is any component whose failure, modification or absence, will affect the safety of the product. Front of 950, defines also defines Safe as not causing a fire hazard. There is no clear cut list of what is safety critical and what is only functional. That is what Safety Engineers and fault testing is for.
