New and Improved UL 1950/CSA 950
Product Safety Professionals, Oops! My apologize. I just realized that the 'next' Santa Clara Valley Chapter of the Product Safety Technical Committee meeting is actually May 28, 1996 on UL 1950/CSA 950. I have prematurely sent out the June meeting announcement in my last email (you may still want to mark your calendar for a good June 25 meeting). For the May meeting, the topic will be on the latest revision to UL 1950/CSA 950, in particular Clause 6 of the telecom requirements. List-Post: emc-pstc@listserv.ieee.org Date: May 28, 1996 Time: 7:00 pm Topic: Clause 6 of UL1950/CSA 950 - Telecom Requirements Speaker: Dan Barsotti, Underwriters Laboratories Location: Hewlett Packard, 19447 Prunridge Ave. Cupertino CA, Bldg. 48, Oakroom (approx. one block north of Hwy 280 and Wolfe) Dinner: If you are interested in joining the speaker for dinner at El Torito's (by Vallco Fashion Park at Wolfe and Hwy 280), it will be at 5:30 pm. El Toritos' had committed a 25% discount for guests of the PTSC. RSVP to Edward Karl at (408) 563-7184. *** News Release ** New and Improved UL 1950/CSA 950 Dan Barsotti, Underwriters Laboratories, will be the feature speaker at the May 28 meeting of the Product Safety Technical Committee of the Santa Clara Valley EMC Society. He will discuss the latest revisions to UL 1950/CSA 950, in particular changes to the telecom requirements in Clause 6. UL 1950, which covers Information Technology Equipment, has recently been re-issued as UL 1950/CSA 950 Third Edition. This is a bi-national standard that is based on IEC 950 Second Edition including the First through Third Amendments. Part of the development process for UL 1950/CSA 950 included combining what were previously UL 1950, UL 1459 (Telecom Equipment), CSA 950 and CSA 225. The previous telecom requirements of UL 1459 and CSA 225 have been used to enhance the telecom requirements of Clause 6 of IEC 950 to create UL 1950/CSA 950. Regards.

FWD>RE>FW- Electrical Safet
Mail*Link(r) SMTP FWD>RE>FW: Electrical Safety To John of Good Will: I disagree with Tania, at least in the United States. First, you need no one's permission to check a toaster to see if it works or shocks. Tania's advice about UL and CSA restrictions only applies if you replace parts or otherwise modify the product. If you do refurbish and sell agency-approved products, you are required to either obliterate the approval mark or go through the procedure Tania describes. Second, I have discussed the applicability of the US National Electric Code (NEC) with other compliance engineers. The wide consensus is that the NEC applies to hard-wired or permanently installed products, but NOT to line-cord connected appliances. Nationally Recognized Test Laboratory, (NRTL) approvals of such appliances is not required by the NEC. Government agencies and municipalities often have regulations requiring NRTL approvals for products they purchase or allow in their facilities. Thus it is legal in the United States to sell unproved products, whether new, used or reconditioned. But most public agencies will not (do not allow themselves to) purchase such products. I think the original request was for information on a safe work environment for the checking (and possible repair) of appliances. NEC regulations apply to the installation, and I highly recommend GFI protectors on outlets. OSHA requirements also apply, but I'm not familiar with them. Safety means such as non-conductive work benches, rubber mats, isolation transformers, and proper training are very important, and liability issues must be addressed. I wish you well. It must be hard to operate a sheltered-work recycle-intensive business in a land ruled by litigation.

RE: FW: Electrical Safety
This is a curious issue. If I were an appliance repairman or service person, I would merely replace defective components, wiring or materials without going through a "refurbishment" criteria. I would think that R&R (repair and replace) is not a refurbishment per se. My initial thought was just to repair these devices and let it go at that.

I am making the assumption that you are reselling in the U.S. and or Canada only, not in Europe. You are grossly afoul with UL (Underwriters Laboratories) or other U.S. and Canadian safety agencies as well as with the NEC (National Electrical Code) requirements that appliances that are fixed, reconditioned, or otherwise refurbished and sold to the public, must meet specifications as originally approved by the safety agencies. Canada (CSA) specifies that only the original manufacturer, or his designated agent or representative, may refurbish equipment. Substitution of parts is not allowed. UL specified, a long time ago, that only the original manufacturer could refurbish equipment. By now they may have added the "designated representative". Check with UL. In order not to run afoul with UL or CSA, you could obliterate their safety marks on the equipment, but then you are in violation of NEC and OSHA, which specify that only appliances approved and labeled by designated Nationally Recognized Testing Laboratories (UL, CSA, and others) are permitted to be installed in buildings (NEC 110-2). Plugging in an appliance is considered an electrical installation. Additionally, you are sticking your neck out with respect to liability should your repair result in a fire or shock hazard to the user. (I can see the headlines right now: "GOODWILL INDUSTRIES INVESTIGATED FOR INCORRECT TOASTER REPAIR THAT RESULTS IN FIRE!") RECOMMENDATION: 1. Write to specific manufacturers asking them to designate Goodwill as their official repair/refurbishing agent. 2. Obtain all their specifications, parts bills, AND THE UL AND CSA PRODUCT REPORTS. 3.

Re: European Power cords
In response to Nick Rouse's comments: I stand to be corrected. Indeed, Member States may thwart the intent of the Directives by doing weird and wonderful things when they transpose/approximate. At times their reasons me not be the purest, but in the UK case, it is clear to the rest of the world that a good plug has a fuse. I believe that every principality has something or other that says that you should use plugs in that country that fit the sockets they are likely going to be plugged in to. The issue in that case is that an ill-fiting plug may cause heating, fire and other unpleasant things. The question now is, if you supply the customer with a box that has a cord and plug that may not fit the local sockets PLUS a cord and plug that WILL fit the local sockets, will that cause enough confusion to lead to unpleasant events. Remember, you meet the letter of the local law that says that you shall provide the proper plug. The issue is whether the improper plug, also included in the package, will be considered likely to cause problems. My take is that this may well vary from country to country. The worst case is if the plug "almost" fits and people who can not read the instructions are going to try. Given the complexities of all the possible combinations, I change my tune and now believe that probably you should not be allowed to give the customer a choice of cords in the box, because it may well be a violation of the LVD essential requirements. Regards, Vic Boersma Vic
Re: European Power cords
The UK measure that relates to power cords is the Plugs and Sockets (safety) Regulations 1994, Statutory Instrument 1994 No. 1768. I have not read this measure but I understand that it requires that mains powered electrical equipment being supplied in the UK and likely to be sold in the UK to domestic consumers must be supplied by the 'first supplier' i.e. manufacturer or importer, with a mains lead with a properly fitted plug. This plug must be either a UK style fused 250V 13A plug to BS 1363A with a correctly rated fuse or a plug to a type approved for use in a EEA member state in which case an approved conversion adaptor to BS1363A again fited with a correctly rated fuse must be supplied. This requirement came into force on 1 Feb 1994. It was not brought in under the Low Voltage Directive (implimented in the UK by Statutory Instrument 1994 No. 3260) but as secondary legislation under the Consummer Protection Act. Such national measures that may be thought to be in conflict with European directives must be submitted to the Commission under Directive 83/139/EEC, as amended, who may order a delay before implimentation to allow for any objection to be raised and dealt with. There were objections from the Commission and others to this measure but they were finally resolved and the measure approved by the Commission. I spoke to Nick Winter who is responsible for the unit at the UK Department of Trade and Industry (DTI) that deals with electrical safety legislation. He told me that in trying to steer the Plugs and Sockets Regulations through the 83/139/EEC mechanism his unit had done a survey of other EEA members states to look for requirements for national style plugs. They found nearly all had some such requirement. Most had, in implimenting the LVD, taken the requirement in Annex 1 1(c) of the directive that 'the electrical equipment, together with its component parts should be made in such a way as to ensure that it can be safely and properly assembled and connected' and implimented it for their state to require that mains connections be made with national style mains plugs and sockets. My conclusion is that it is fine for the distributor in the UK (who as importer becomes first supplier) to substitute UK power cords for US ones for units for sale in the UK. There is a good chance that it would be fine to substitute other other power chords for other destinations but you would have to examine the national laws in each state to be sure. All this demonstrates that Europe is very far from a single market. Vic Boersma says that 'the issue here is not UK Statutes, but EU Directives, which are legally binding laws of the European Union that become mandatory by their transposition into national laws of the Member States.' This misses the point that the directives are not in themselves legally binding on individuals or companies. Member states are treaty bound to 'approximate' national laws to the directives but these approximations, which are legally binding on indivduals in that state, are in many cases just that, approximate. Member states can, via the 83/139/EEC mechanism introduce national measures in derogation of the principal of the free movement of goods and several hundred such measures have been notified under this mechanism. The Commission can bring member states to court for incorrect implimentation of the directives and in one case an individual successfully challenged a member state's implimentation of a directive in the European Court but such litigation is not for the faint hearted. Vic was however much nearer the truth than me in one other matter. In a recent post he used the definition of rated voltage in IEC950 to deduce that the LVD did not apply to equipment that was powered by a voltage below the limit but generated voltages within the limits. I'm still not sure of using IEC950 but the conclusion he came to agreed with the interpretation of phrase 'designed for use with a voltage rating of ...' given by Nick Winter at the DTI. They regard the directive as applying only to equipment powered by voltages within the stated limits Nick Rouse
