– 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);
