Re: [PSES] Insulative barriers deposited on metal surfaces

Hi Brian: I work mostly with UL 60950, so I can only offer a few general comments about the use of solid insulation to reduce clearance distances.  I have seen several cases where a manufacturer wanted to use a coating of some sort to provide a layer of solid insulation.  In UL 60950, the minimu

Re: [PSES] Insulative barriers deposited on metal surfaces

Some UL and CSA standards spec up to min 3mm of ceramic material for use as insulation from haz V. And some safety stds have no min thikness for ceramic stuff. And you can infer from temperature tables in various standards that ceramics can be considered supp or rein insulation. But I am not certai

Re: [PSES] Insulative barriers deposited on metal surfaces

The standards we are typically working with are UL1564, CSA 107.2, and UL2202, however many of the older North American standards have comparatively large distances between live parts and enclosure. These locations are specifically not allowed the easements found in UL840, and instead, the dista

It might be helpful for the discussion to know the Standard that applies to the component you are certifying. -Ken On Tue, Jul 17, 2012 at 6:03 PM, Brian Ceresney wrote: > Hello Compliance Experts, > > I'm interested in the use of a high temperature insulator, possibly a > ceramic, whic

Interesting. Have you used these drivers for other than immunity tests? The boss wants me to 'convert' my stuff from Linux to Windoze - could this save me the associated pain and agony and inexorable passage of time? Brian -Original Message- From: emc-p...@ieee.org [mailto:emc-p...@ieee
