Rechargeable Batteries
I hope you'll all be patient with what might be a question with an obvious answer: why do so many battery operated equipments state that they must not be operated using rechargeable batteries? I appreciate that NiCads have a nominal voltage of 1.2V compared to Alkaline and Zinc Chloride's 1.5V, but is there something else of which I'm not aware? Higher output impedance as they grow old? Greater chemical toxicity? More likely to leak corrosive material? More likely to explode?! Is it functionality, safety or EMC that worries the instruction book writers?

Re: ITE Safety
Courtland, UL 1950 (and IEC 60950) clearly define their scope as "mains or battery powered" equipment up to 600V. Your 5Vdc input device does not fall within this scope, unless it also operates on batteries. The standards define a Class III device, operating at similar low dc voltages. However, this might apply to a battery powered laptop. If your device operates at SELV voltages, is powered by an external 5Vdc,and does not use batteries, I know of no mandatory UL Listing requirement. You should convince yourself that it is designed to avoid sharp edges and spread of fire. My opinion..

If a device uses an external power supply that supplies +5V DC and has all the approvals (UL, CE), is there any need to have the device tested to UL 1950?

RE: UL 1950 D3 deviations.
Hello Terry: D3 Deviations do not expire this year. 2nd Edition is dead...that is correct. Specific D3 deviations, like anything else in the standard, may be added, deleted, or changed with ammendments or editions to the UL 1950/CSA 22.2 No. 950, but in general D3 deviations are not going away.

Hi again: In the course of a design review the option of invoking a D3 deviation came up. Since we usually ship to the EU I have never allowed D3 deviations. The question came to mind that I thought the D3 deviations expired this year. Is this a foggy memory from UL 1950 2nd edition 1993 Supplement C expiring March 15, 2000? I tried to see an expiration reference in the 3rd edition but couldn't find it. Does this then amount to a `National Difference' or am I missing something in my searching of the Third edition?

Surge generators reliability
Hello all: We are reviewing the probability of purchasing a surge generator to do in house compliance testing to the EN 61000-4-5 standard plus up to 6KV for some customer specific requirements. We have quotes from most of the major players and the equipment ranges from very basic cost effective EN 61000-4-5 testers that go up to 2.2 KV to more Test lab orientated ungradable equipment. Questions: 1. Does anyone have any advice they would like to give in the implementation of this test? 2 . Does anyone have any bad experience or good reviews of the equipment they use that they care to share directly to me? Best regards, Terry J.

Re: Laser Safety Product Labeling
Thomas, You need consulting from a renowned laser specialist. I recommend you contact my colleague at TUV Rheinland of North America Woody Strzelecki at TUV Rheinland of North America; he will guide you to exactly what is required. His e-mail is wstrzele...@us.tuv.com. One note I have to mention is that classification is made based on normal conditions and single fault conditions. Good luck and do not look into that fiber!
