Hello Tim, The new sound pressure levels were published by CENELC earlier this year for the EN60065 Audio Video Standard in Amendment A12. They were just recently adopted by BSI so you can get a copy of EN60065:2002+A12:2011 with the new requirements. The Date of Publication (DOP) for

SAE J-2344 is for EVs, but the hi-current bus construction is relevant. Make power connections to vehicle electrical power only after the fuse block to a node intended for aux power, and use connector certified to UL2089. Brian -Original Message- From: emc-p...@ieee.org [mailto:emc-p...@

RE: Vehicle Power Safety

Yes Ed, voltage is certainly one part of the equation but the real issue is current associated with it. In your case take a look at mil –hdbk-454B section 5.2 electrical shock and table 1-I. Commercial standards also require protection from contact with hazard voltage (generally greater than 60 Vdc

RE: GPS interference under consideration by FCC

Cliff is referencing the Lightsquared proposal, which raises questions of significant interference to GPS users. This is FCC Docket 11-109, and so far, the FCC has over 1400 comments to this proposal (and I didn’t see even one in favor of Lightsquared). The face-off is essentially cell-phone sp

Vehicle Power Safety

This is way out of my area, as all I know about safety is that I’m supposed to keep at least one hand in my pocket at all times. But seriously, is there any safety code or spec that address the human safety hazard of a 24 VDC vehicle electric system? Although the voltage level seems to preclude sho

GPS interference under consideration by FCC

For all of us that make GPS products for the US market, or are users of the GPS system in the US, there is something that may be of interest to you. There is a technology under consideration by the FCC that seems to have a significant potential for interference to some GPS receivers. I woul
