Intermediate Bulk Containers (IBCs) intended for the carriage of dangerous goods are required to undergo initial inspections and subsequent periodic inspections at 2.5 and 5 year intervals. These tests and inspections will need to be repeated following any repair (but not following routine maintenance). The main requirements in relation to testing and periodic inspection of IBCs are set out below:

Before being filled and handed over for carriage, every IBC must be inspected to ensure it is free from corrosion, contamination or other damage, and that any service equipment functions properly. Any IBC which shows signs of reduced strength as compared with the tested design type must be repaired or routinely maintained before it is used again.
