WHAT IS EN61340-5-1
Static charge can build up on the body for a number of reasons including personal attire, atmospheric humidity and the way a person walks and moves. A build up of electrostatic discharge (ESD) can damage sensitive electronic components or create fire risks when handling solvents and other flammable materials.
In order for electrostatic sensitive devices (ESDS) to be handles with minimal risk of damage there are specific technical requirements for the design, use and control of an electrostatic protected area (EPA). This includes the use of ESD control items such as garments or footwear.
HOW IT IS TESTED
Compliant garments must be clearly marked and must completely cover all clothing in the arms and torso region. The point to point resistance over the outer surface must be less than 1012 Ω.
POINT TO POINT RESISTANCE
The point to point resistance is a measure of the conductivity of a material between two point. Conductive fibres in garments work by preventing the static charge build up by allowing it to dissipate through the conductive fibres and go to earth.
LOWER IS BETTER
The lower the resistance, the higher the conductivity and the lower the risk of electrostatic discharge.
