Re: IEC 60990 Vs IEC 60950

Kevin, You do provide valid points. However, how many times have you shucked out $60 or $80 for a referenced standard, only to receive a 15 page document? I have, a few times, which makes me very reluctent to rush out and buy everything that is referenced. If the standards were "reasona

Hi Listmembers: Today's weird science question is about sensing the strength of a permanent magnetic field. I need to expose an electronics box to a strong magnetic field (10 Gauss). Then, after removing the field, I need to approach the box with a "compass" and note the separation distance need

Most of the world entered the information some decades ago. The greatest leap forward has been the advent of the internet. I need not elaborate on how quickly one can get information on almost any topic at their workstation via the internet. Sadly, the world of standards is stuck in the 1950's.

1999-09-30 Thread Brian At Work
Our company makes laboratory equipment so we perform radiated emissions test per EN55011 and apply the CE marking according to EN50081-2 or EN61326-1. Some of our products would fall under the Class A Group 2 category in EN55011, but neither the EN50081-2 or EN61326-1 seem to address this route.

Nick, et al, Dare I suggest this? Why don't we create a large standards depository on the web and have all of these standards hyper-linked together. Then, for a reasonable subscription fee, one could log in and read any standard in existence. Best of all, one could take the hyper-jump to that spe

You can only use this clause if your equipment will not be mounted above other equipment in the telco frame. So basically, if your equipment occupies the entire 7' or 11' foot high frame or your equipment is "always" on the bottom, you could uses this exemption. Be cognizant of the consequence

When I dealt with telecom equipment (IVR) at my last company . . . we didn't take that clause. Our reasoning was that it was easier to make one enclosure configuration for use in either a CO or office (telephone room) environments. There could be instances where a customer could change the locatio
