EVS-EN 61340-4-4:2012

This part of IEC 61340 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 may be created by the contents in the FIBC or may exist outside the FIBC. The requirements include: - classification and labelling of FIBC; - classification of inner liners; - specification of test methods for each type of FIBC and inner liner; - design and performance requirements for FIBC and inner liners; - safe use of FIBC (including those with inner liners) within different zones defined for explosion endangered environments, described for areas where combustible dusts are, or may be, present (IEC 60079-10-2), and for explosive gas atmospheres (IEC 60079-10-1); - procedures for type qualification and certification of FIBC, including the safe use of inner liners.
