TÜV SÜD Process Safety owns an accredited electrostatic laboratory, where we can carry out different tests for you :
Surface and volume resistivity
Classification of material, expecially for clothes and shoes
Space charge density measurement
Certification of Flexible Intermediate Bulk Containers (FIBCs)
Flexible intermediate bulk containers are being used increasingly in those industries that process powders. FIBCs should comply with various requirements designed to preclude ignition hazards due to electrostatic charge. These requirements depend on where the containers are used, and are divided into Classes A, B, C and D.
The benefits for you
A few laboratories only carry out the classification of flexible intermediate bulk containers. With the laboratory of TÜV SÜD Process Safety you benefit from decades of experience in the field of electrostatics and explosion protection. All tests carried out for classification purposes are accredited ISO/IEC 17025.
We provide certificates of validity for all kinds of liners and FIBC. Our tests are carried out in agreement with the requirements of the IEC 61340-4-4 2nd edition especially the conditioning of the bag. We own a climatic chamber large enough to welcome and test a bag as a whole. We are independent and neutral that is why our certificates are recognized and trusted by large chemical and pharmaceutical companies.
In order to help our partners we perform the certification process firstly via a screening test. If the screening show values in the ranges defined by the standard 61340-4-4 2nd edition, we automatically carry out the certification. If the screening is bad, we inform our partner and only invoice the screening. Of course, a screening test is much cheaper than a complete certification process.
What do we need as a sample.
In order to get a certificate, we need a full piece of the bag to be tested. We do not deliver certificates for foils to be liners or fabric. The reason is that we often observe a spatial variation of the breakdown voltage or surface resistance.

Testing the leakage resistance of floor coverings
The accumulation of electrostatic charges is mainly a hazard in locations where, under certain conditions, it can cause an ignition to occur. Even in places where there is no special fire hazard, electrostatic discharges can be an unpleasant phenomenon, and can cause accidents or technical faults. The accumulation of electrostatic charges can be counteracted by means of conductive floor coverings.
The benefits for you
All tests carried out to determine leakage resistance to earth; surface resistance and breakdown voltage are accredited ISO/IEC 17025.
Measurement of the leakage resistance to earth according to EN 61340
Determination of the surface resistance of samples to IEC 60093
Determination of the breakdown voltage of insulating layers to EN 60243
Consulting and evaluation of new developments in floor coverings
