Electrostatic Testing
Protect Against Electrostatic Hazards and Harness Electrostatic Potential
Electrostatic discharges pose fire and explosion risks. Knowing how static electricity affects your business is the first step towards safety and progress.
Our electrostatic testing focuses on hazard identification, problem resolution, and application innovation. Electrostatic hazard assessments, on-site measurements, and charge elimination/control are all part of our focused, disciplined approach to minimizing the dangers of static electricity, in addition to a comprehensive range of laboratory tests. We engaged in electrostatic research in the fields of powder processing problems, environmental applications and biotechnology, among others.

More Background Information About Electrostatic Testing
Static electricity is the charge that is generated whenever any two materials make and then break contact. Static electricity is generated during many common processing operations in industry: for example, when liquids flow relative to pipe walls or when powder particles come into contact with the surfaces of the processing and conveying equipment.
A great concern posed by static electricity in an industrial setting is the risk of fire and explosion due to the ignition of flammable atmospheres by electrostatic discharges. Combustible dust and flammable materials are used in many chemical processing operations and precautions are required to prevent their inadvertent ignition. If the energy of the electrostatic discharge is greater than the minimum ignition energy of the flammable atmosphere, a fire or explosion hazard will exist and measures should be taken to avoid the conditions under which such discharge could occur. If the exclusion or elimination of electrostatic ignition sources is not practical, other measures such as avoidance of flammable atmospheres or explosion protection must be considered.
