Re: German Equipment Safety Law
Hello Richard, Although the following is not a direct answer to your query, it appears to be relevant to your interest/s. In the current issue of TUV Rheinland's newsletter "World News" (March-April 1998) on page 5 there appears an article titled, "New German Law Closes Gaps". Therein it is stated, "Germany is enforcing a new product safety law, made effective August 1, 1997, entitled, "Law to Regulate the Safety Requirements for Products and Preservation of the CE Marking" (translated). It further states, "This law, which implements both a European Union (EU) Directive and the Product Liability Law of 1989, closes remaining gaps among the product-specific safety laws, such as the Pharmaceutical, Food, or Equipment Safety Laws (GS Law)."

Re: Life Cycle Testing - PS
Shelly, Do we know the most probable failure mode. We might get this information from the supplier of the PS. Richard Haynes P.S. I have included a copy of this e-mail to one of the leading experts in the Field of Accelerated Testing: Tony Chan at AT&T Bell Labs. -Original Message- From: SRZIMMER To: emc-p...@majordomo.ieee.org List-Post: emc-pstc@listserv.ieee.org Date: Thursday, April 30, 1998 2:46 PM Subject: Life Cycle Testing - PS >Gentlemen/Ladies: > >Does anyone have information on Life Cycle Accelerated Testing of external >Power Supplies?

German Equipment Safety Law
My copy of the Equipment Safety Law has a revision date of 1980. Does anyone have a later revision or can verify that the 1980 revision is the current revision?

RE: LEDs and the Laser standard - question
Heber - This may depend on who's doing the certification of your equipment. I've heard of certain agencies ignoring faceplate LEDs, but not yet of any wanting to test. According to Jerome Dennis of the CDRH (at the 1997 International Laser Safety Conference), discussions at the IEC TC76 meetings indicated acceptance of manufacturers' data sheets as an acceptable means to determine compliance. This may, however, require conversion of units from candela or lux to units consistent with IEC825-1. Regards, Peter L.

Life Cycle Testing - PS
Gentlemen/Ladies: Does anyone have information on Life Cycle Accelerated Testing of external Power Supplies? Are there standards or test specifications? Can anyone recommend a test lab?

ISO Standard for SI units (Metric Directive)
Greetings, Thanks to all who have provided information on the metric directive. As I was researching this issue, I went back to the FAQ by Bill Lyons. What a great resource. However, I was not able to find the standard that would be used to comply with the directives. Could someone please forward the standard number that spells out the metric units of measurements? BTW I sent an email to NIST (from the information supplied by this group) and here was Mr. McCracken's response: Mr. Russell, At this time no meeting is scheduled to discuss the EU metric-only directive. The EU technical staff has proposed a ten year delay of the directive. Until we know more on the subject a meeting is not warranted. We will continue to make information available. Jim McCracken Metric Program Thank you for your assistance, Ray Russell ray_russ...@gastmfg.com
