Article VI of the Convention
refers to the control measures that may be taken by Contracting Parties.
Such control should be limited to verifying that the container carries
a valid Safety Approval Plate, and an approved continuous examination
programme (ACEP) or a valid Next Examination Date (NED) marking, unless
there is significant evidence for believing that the condition of
the container is such as to create an obvious risk to safety. This
Annex provides specifics to enable authorized officers to assess the
integrity of structurally sensitive components of containers and to
help them decide whether a container is safe to continue in transportation
or whether it should be stopped until remedial action has been taken.
The criteria given are to be used to make immediate out of service
determinations, and should not be used as repair or in-service criteria
under a CSC ACEP or a periodic examination scheme.
