Sparkplug HV standards

Udtwmc
Hello,


Anyone know which standard covers sparkplugs, specifically protection against direct contact of the high voltage electrodes? 40,000V


I have an exposed sparkplug designed to ignite a flammable atmosphere such that the electrodes protrude outside its enclosure. This is in a restricted access area but i would still like to include a grill around the electrodes to prevent direct contact, but not sure what IP rating i need to comply.


BS EN 60204-11 states Ip4x, but again i'm not sure a sparkplug falls under HV power standards?? I'd hope to go with IP2x if i can to allow as much gas to engulf the spark plug.


Thanks

    I assume that the spark plug in question resembles an automotive one (or even lawnmower/chainsaw/etc). I have had a few belts off a spark plug lead and I would say that one off the 230 V mains is worse.


    I wouldn't be worried about the exposed tip of a spark plug. Access is pretty limited when you bear in mind that the earth electrode(s) keep fingers away.


    The socket on top of an old-fashioned coil in a motor car (or even more old-fashioned magneto) is only IP2X.


    Depending upon how the voltage is produced, surely the biggest risk would come from a defective cable, but from the sound of it, the cable is enclosed.
