[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.

Australia power grid
Group, We have some indirect evidence, and some damaged product, that appears to be related to over voltage on the power grid in Australia. The nominal is 240V 50Hz, but we are hearing accounts of voltages as high as 285V.

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.

I'm wondering if this sort of accelerated life testing is something out there for the satellite and space shuttle designers, rather than for ITE and Telecom equipment manufacturers. For those that did do some of this, did you break the bank and use 6 months of your life for this testing, or was it relatively quick and painless (yeah, right)? We're considering shaking and baking our telecom unit using these types of tests as a design verification tool, but one doesn't hear much about it on the newswire... Dwight p.s.

You get 90 seconds of recording time (more with fancier models). I bought mine at Office Depot for $30.

RE: Flame Retardants in Europe
Darrell, I had this information on record. Maybe it will assist your efforts. ** On July 6th, 1994, the German Government formally revised the Chemical Prohibition Regulation to include various congeners of brominated dioxins and furans. This legislative action, referred to as the German Dioxin Ordinance, restricts he allowable concentration (parts per billion level) of brominated dioxins and furans in products sold in Germany. 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.

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

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.
