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

    Agree, any common type of spart plug will have very limited energy and despite the voltage is most unlikely to be dangerous. (avoid touching though as it will hurt, and might be dangerous under some unlikwly conditions)


    I would treat an 11KV DNO overhead line with a great deal more respect than a spark plug operating at several times that voltage.


    Remember that almost every motorcycle has one or two high voltage spark plugs withing easy reach, the high voltage connections are accessible without a key or tool. And how many motorcyclists are killed by shocks from the ignition system ?
