The container in question does not specify a design service life according to the original regulations; therefore, whether it can continue to be used after ten years of use depends on the results of inspections carried out during its operation.

Based on this interval, economic considerations can be taken into account to decide whether it is appropriate to continue using the container or to have it replaced.
