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.
