[PSES] optoisolators
Group, I would like to get some input on how 60950-1 people and others deal with 60950-1 2.10.5.4 Semiconductor devices: optoisolators We are dealing with the issue of option a) vs option b) to show compliance. The end goal is to identify that the component satisfies the following, a) - passes the TYPE TESTS and inspection criteria of 2.10.11; and - passes ROUTINE TESTS for electric strength during manufacturing, using the appropriate value of the test voltage in 5.2.2; or b) for an optocoupler only, complies with the requirements of IEC 60747-5-51), where the test voltages as specified in 5.2.6 (of IEC 60747-5-5): - the voltage V ini,a for TYPE TESTING and - the voltage V ini,b for ROUTINE TESTING, shall be the appropriate value of the test voltage in 5.2.2 of this standard. We do a routine electric strength test, and the parts are certified to standards older than IEC 60747-5-5. Experience on what option is being used in industry may give me some additional direction. Appreciate your input, as always.

[PSES] IR illumination
Forum, We have a low voltage camera (class 3) that appears to NOT legally require a NRTL certification for National Electric Code acceptance. The product is powered by a LPS and should therefore be out of the jurisdiction of the LVD also. However, the camera also houses an IR light bank (presumably risk class 1) and marked with: NOTICE IR emitted from this product Use appropriate shielding or eye protection I am concerned about there being some LEGAL requirement limiting or requiring marking for brightness. (i.e it needs certification.) I'd like to know, that even with the IR LEDs, the camera can be put on the market with a CE marking, without further investigation. (i.e., it does not required certification.) As always, any assistance is appreciated.

RE: NEMA versus UL type - environmental ratings
We have recently dealt with a similar situation, and have concluded that: At least for NEMA 3R and NEMA 4, Yes, NEMA 250 = UL 50 type. The tests are worded slightly different. Yes, you can self certify to NEMA NEMA vs. UL; NEMA rating shows compliance with tests. UL type shows compliance with UL50 and UL476C where applicable, essentially same tests as NEMA, and subjects the equipment to UL recognition and follow-up criteria. As for UL types, in our case, the UL type allows us to put into the listing report that the product meets the requirements of NEMA. I think that the inspectors are more familiar with, and are looking for the NEMA rating. By having UL list the product, we are having a 3rd party say we meet the NEMA. James Goedderz Product Safety Engineer Sensormatic -- From: Chris Wells[SMTP:cdwe...@stargate.net] Reply To: Chris Wells Sent: Tuesday, July 31, 2001 10:53 PM To: 'emc-pstc' Subject: NEMA versus UL type - enviromental ratings I'm looking for some feedback on NEMA versus UL type - environmental ratings for faceplates of panel mounted components. * First reality check - Are NEMA housing ratings = UL type, number by number? * Second - Can one self certify compliance to NEMA ratings? * Third - What is the difference between NEMA and UL type? I think of the NEMA rating as a proof of design test = rating while the UL type wants design verification at a deeper level? * Forth - Do any of you care about UL types? Our sister divisions design assemblies that use our components and use UL to inspect the design. That is where the pressure is coming from over NEMA. Our product line consists of components mounted to the door of an industrial type enclosure. A pollycarbonate faceplate frames an overlay that contains membrane pushbuttons, embedded LEDs and a window to see our alpha numeric or grahpic display. Between the faceplate and the enclosure panel is a gasket to help keep out moisture, dust etc. We can meet NEMA 1, 12, 3, 3R and for some designs 4 as long as the user installs the component in an enclosure of equal protection. We have tested our design at environmental extremes and it works well. Where it gets difficult is when UL wants an adhesive for the overlay that is specifically qualified to our particular plastic over the range of specified environmental withstand. They want more than a type test and follow up construction inspection but a rather lengthy performance test that goes beyond what we are prepared to do - as if we were the overlay manufactures. Part of the problem is that we have a special additive to the PC plastic - stainless steel fibers for ESD control. This is making for special combinations. So what do others do? Do you have overlay vendors that have coordinated recipe of components/adhesive etc. that works with pollycarbonate from -40 to 60C and comply to UL types (NEMA) types 1, 12, 3, 3R, or 4?

RE: Correction - When is an LED evaluated to IEC 825, like a Las er?
Kathy, We have one agency that we deal with that has insisted compliance with the IEC825/LED issue. We went to the LED vendors and found that they generally have not addressed this issue. We drew a big blank there. Originally, we were submitting LEDs for measurement to the agency. Currently, the agency has developed a formula which when evaluated, gives a pass/fail criteria for class 1. The formula is based on the aperture of the emitting area, the wavelength, and the intensity (mcd) at the operating current. We had one instance where we chose to reduce the current to a high intensity red LED in order to avoid the additional warnings that were required. The observable intensity change was not that noticeable. The acceptable range of mcd varies a lot between the different colors. We have stayed below 800mcd lately, and not had any problem.

Ground lugs
Happy Holidays group, In getting agency approval on our I.T.E. product, the safety ground terminal has come into question. When hard wiring a product, Para. 3.3.7 indicates that the conductor is to be clamped between metal surfaces, and the terminal shall not damage the conductor. This has been interpreted as the terminal must have a metal plate that clamps down on the conductor, and no rotational stresses from the screw are applied to the conductor. In Europe, I understand that a rail terminal block, where one of the terminals is shorted to a rail, is generally used, and accepted, but somewhat costly. There may also be alternatives, but we haven't found an off the shelf one yet. I am looking for a grounding terminal that accepts #14-#18 AWG wire, has a clamping plate, is tin plated, and has a mount or hole for direct connection to a chassis. Since this has been so difficult a component to find, we had one designed. Now my question is, How is everyone else dealing with this ground lug requirement? Is there a common component available that meets these specs? The ground lugs in common use in the electrical industry do not have the plate, and are copper or copper alloy.

RE: NRTL acceptance
Terry, We have used four agencies through the years, and still have many products with other than our main agency. Over the past three years, there was one incident with a NEC inspector that did not correctly identify the backwards RU of a very famous NRTL. There were a couple of other times where the inspector was looking for a certain mark, and flagged us until we could explain that we used a different agency. So generally speaking, there is sometimes an education process required. On the positive side, the NRTL involved has always been very helpful in the education process.

RE: HALT/HASS Testing
Dwight, Our engineering group regularly sends products out for HALT testing. We design ITE, although not computers. Some of the system problems that they uncover are broken solder joints (mass of component), poor connections (circuit boards), and other mechanical problem (fasteners). The main idea is to increase the thermal stress on the product, with vibration, until failure occurs. The test temperature starts at your maximum operating temperature. The products generally undergo about 3 days of testing. The cost is related to how long it takes to verify functionality. We need about 15 minutes. It will cost you about $8k for 3 days of test. You will need to either send an engineer, or include a lot of replacement parts. Figure about two months to schedule.

Brominated compounds thought to generate these dioxins and furans may be used as flame retardants in plastic resins and components using plastic resins. The law will prohibit marketing in Germany any substance, preparation or product containing more than the specified limits for the brominated dioxins and furans listed in the ordinance. Products and parts that weigh less than 50 grams are exempt from the limit requirements for some compounds.

We were told by our molder that the material we wished to use contained polybrominated diphenyl ether (PBDE) as a flame retardant additive to achieve the required flammability, and that these additives have been banned in Europe. I have been trying to identify which law, regulation, or standard states this but all I have found so far is mostly heresay. Can anyone give me any more definitive information on the prohibition of these flame retardants in Europe. Thanks as always Darrell Locke Advanced Input Devices
Cordage
Hello group, I have a vendor that wants to sell us line cords for use in Europe. There are several agency marks on the cordage, but no HAR. The plugs have several agency approvals. Does anyone know the legal requirement for marking the cordage. I have seen references to HD-21 and HD-22, but do not have a copy. Apparently these indicate that either the approval agency, or the HAR is to appear on the cordage. Thank you for your responses. James Goedderz Sensormatic
optocoupler
Does anyone have knowledge of VDE 0884, 'optocouplers', and why it is more difficult to get approval to than UL1577 Optical Isolators? Particularly, the Dielectric withstand voltage required, and something about charge transfer between the emitter and detector. Thank you James Goedderz goedd...@sensormatic.com

Signal Words
In an effort to be as compliant as possible, the following concern has been raised by one of our technical writers. I know I have seen information on this in the past, but need a refresher. Does anyone have details on when a warning or caution should, and should not be used? Some sources indicate that a warning is related to personal injury, and caution to product damage. Secondly, is there official requirements for letter height, bolding, spacings of additional text from the Warning keyword. Some UL standards indicate 2.8mm minimum for the precautionary word, and other words to be 1.6mm high, and contrasting to the background. (UL1409) Thank you in advance for any assistance.

Bromine
Safety People: A few years back, I remember there being some controversy, or dictates, about the use of plastics containing bromine (to improve flammability rating). I am unable to find any of the reference material on this, and would like to know if anyone has information concerning laws, prohibitions, permissions of use, or whatever, especially as regards the use in Europe. Thank you for your assistance. * Jim Goedderz * goedd...@sensormatic.com * * *

RE: ISO306 Vicat softening temperature
My company does this type of testing, and uses a setup from a now defunct European manufacturer. We have replaced many parts, but can't say that we built it up. ISO 75 and ASTM D648 are very similar, the main differences being in the different force used, and the separation of the supports. If you build one up, pay particular attention to these items. One possible source for a commercial piece of equipment is Atlas Electric Devices, out of Chicago.

RE: Crock Pots
There are many examples of getting shocks from the leakage currents which you will find in many appliances, especially when there is excess moisture involved. Before Bill gets the CSPC and UL too involved, perhaps some resistance measurements, or leakage readings are in order. A DMM voltage reading could show almost the full voltage, when measured to ground. What you need to do is get all the facts before you try to make a case. _ James Goedderz Entela, Inc. jg...@entela.com The opinions and views in this message are my own, formed in the midst of a hectic day, and do not necessarily represent the opinions of my company. -- From: rbusche Sent: Friday, May 24, 1996 8:22 AM To: jgoed; PSTC group Subject: FW: Crock Pots You might find this interesting __ _ _ To: Multiple recipients of list SAFETY From: Safety on Fri, May 24, 1996 5:18 AM Subject: Re: Crock Pots In a message dated 96-05-24 02:17:59 EDT, you write: A few days ago, one of our food service workers received an electric shock when her hand touched a crock-pot while wiping down a countertop. Bill's experience is just one more good example of (1) why talking about near misses is so important and (2) a hazard that is not well recognized. Two-prong unpolarized plugs and miswired recepticals with the hot and neutral reversed lead to the case of appliances being hot. According to Ed Egan at OSHA, 35 people die annually from fatal shocks of this origin. JCAHO and CAP both ask for annual checking of electrical equipment for voltage leaks. Ground Monitors or circuit analyzers should be use to check the receptical wiring. The two-prong unpolarized plugs should be replaced with three-wire cords and plugs. In the meantime, remember, the ripple side of the cord goes to the wide side of the receptical. If you saw a drunk coming at you with a jug of Ripple, most of you would stay wide of him or her!
