Re: [PSES] Spark Ignition Source

A common source used for calibration of the spark test chamber for intrinsic safety testing is a 95 mH air core inductor connected to a 24vDC source with current limiting that is adjusted based on the gas group you are using.   Kevin Robinson On Tue, Aug 16, 2016 at 7:57 PM -0400, "Doug

Re: [PSES] Spark Ignition Source

Is typically two different things - the ASTM E2019/EN13821 MIE stuff or the Mil stuff based on an LEL mix. Has been a very long while since these tests were witnessed, but do remember that the MIE tests can be rather sensitive to the shape of the VI curve per time, so L needs good control.

[PSES] Spark Ignition Source

All, I am looking for a supplier of electrical spark ignition sources used in flammable vapor or dust testing. It needs to have a calibrated energy level and be able to provide two sparks per second with sufficient energy to ignite natural gas. Any help is much appreciated. All the best, Doug

Re: [PSES] Presumption of conformity Question

Hello everyone I have raised this question to an EMC Directive desk officer I know at the EU commission, but there are no promises as to getting an answer back! Regards Nick Nick Hooper BSc(Eng) PGDip CEng MIET SMIEEE Chairman R CA / RED CA

[PSES] Presumption of conformity Question

Dear Colleagues In 2014 CENELEC published an amendment to the EMC standard for alarm systems EN 50130-4:2011/A1:2014. In all the time since the commission failed to post it in the OJ for the old EMC directive to the considerable detriment of manufactures of alarm equipment. In May of this

Re: [PSES] EU OJ today - EN55013/20 missing

Michael, I agree that the committee for EMC may remove these two standards that should go to RED now.  Unfortunately, the committee for RED does not do the handover seamlessly. Regards, Scott From: Michael Derby Date: Tuesday, 16 August 2016 at 3:41

Re: [PSES] EU OJ today - EN55013/20 missing

Hi Scott, I suspect that the exclusion of EN 55013 and EN 55020 from the latest EMCD OJ is now an intentional thing, based on the fact that those products are no longer intended to be used with the EMC Directive….. even though we know that they are, during this short transition period. I
