BS EN IEC 61340-4-4:2018 pdf free download.Electrostatics. Standard test methods for specific applications – Electrostatic classification of flexible intermediate bulk containers (FIBC).
BS EN IEC 61340-4-4:2018 specifies requirements for flexible intermediate bulk containers (FIBC) between 0,25 m3 and 3 m3 in volume, intended for use in hazardous explosive atmospheres. The explosive atmosphere can be created by the contents in the FIBC or can exist outside the FIBC.
FIBC are not normally used in Zone 0 or Zone 20. If FIBC are used in Zone 0 or Zone 20, the requirements of this document are applicable, together with additional requirements that are beyond the scope of this document to define.
The volume contained within FIBC can be designated as Zone 20. in which case the requirements of this document are applicable.
Solids containing residual solvent can result in a hazardous explosive atmosphere within FIBC, possibly resulting in the volume being designated as Zone 1 or Zone 2: in which case the requirements of this document are applicable.
Compliance with the requirements specified in this document does not necessarily ensure that hazardous electrostatic discharges.
Compliance with the requirements of this document does not mitigate the need for full risk assessment. For example, metal and other conductive powders and toner powders can require additional precautions to prevent hazardous discharges from the powders.
