10 20 Humidity Static Electricity Vinyl Envelope

Unfortunately 60 relative humidity is extremely uncomfortable can cause equipment problems and introduce contaminants into your system.

10 20 humidity static electricity vinyl envelope. Walking on a vinyl tile floor. Means of static generation. Walking across a carpet. During the summer the indoor humidity tends to be high.

Increasing humidity to 60 limits static build up because surface moisture on materials makes a good conductor. Walking on a vinyl tile floor 12 000 v 250 v.

During the winter the humidity inside a heated space can be very low. Two levels of relative humidity rh ref. Worker at bench 6 000 v 100 v. Vinyl envelopes for work instructions 7 000 v 600 v.

Vinyl envelopes for work instructions. Means of static generation rh 10 20 rh 65 90. This increases the condutivity of most things enough that static charges are drained off. Static is rarely a problem.

Static electricity 1 like lightning. The shock is from the build up of static electricity.
