WHAT IS EN 61340-5-1?

Is a standard that applies to the protection of electronic devices from electronic phenomena.

Personal apparel, air humidity, and the manner a personwalks,and moves are all factors that might cause static charge to build up on the body. When handling solvents and other flammable compounds, electrostatic discharge (ESD) can harm sensitive electronic components or cause fires.

What is ESD?

ESD stands forElectrostaticDischarge.

There are special technical criteria for the design, operation, and control of an electrostatic protected environment in order to handle electrostatic sensitive devices (ESDS) with minimal risk of damage (EPA). This involves the usage of ESD-controlling clothing and footwear.


Compliant apparel must be prominently labelled and completely cover all clothing in the arms and body. Over the outside surface, the point-to-point resistance must be less than1012 Ω.


The point-to-point resistance is a measurement of a material's conductivity between two points. Conductive fibres in clothing work by allowing static charge to drain via the conductive fibres and go to earth.


The lower the resistance the higher the conductivity and the lower the risk of electrostatic discharge.

Why should you be concerned about ESD?

During the manufacturing of electronic assemblies and equipment, ESD can cause hidden damage to electronic components. If the damaged component fails right away, the board may fail tests and need to be reworked. This translates to a loss of production and an increase in manufacturing expenses.

Worse, a component may be partially destroyed and weakened as a result of this. It's possible that its qualities will change or drift. It may meet specificationsbutfail whenusedby a customer. It is estimated that 90% of broken devices will be identified in this manner. This is the costliest sort of failure since it entails:

  • Customer displeasure, as well as the risk of a product's reputation and future sales being tarnished
  • The cost of customer service staff as well as the facility expense
  • Engineers' time, possibly for on-site repairs and parts replacement, as well as travel and call out charges.
