Freight containers — Mechanical seals

ISO

17712

This International Standard establishes uniform procedures for the classification, acceptance, and
withdrawal of mechanical freight container seals. It provides a single source of information on mechanical
seals which are acceptable for securing freight containers in international commerce.
NOTE The purpose of mechanical seals is, as part of a security system, to determine whether a freight
container has been tampered with, i.e. whether there has been unauthorized entry into the container through its
doors. Seals can be effective only if seal users properly select, store, account for, apply, document, and attend to
seals prior to use and in use; while these issues are not addressed in this International Standard, they are relevant
to successful use of the seals covered by this International Standard.
Seals that conform to this International Standard are suitable for other applications, such as bulk railcars
or truck trailers used in cross-border and domestic operations. Users and regulatory agencies can apply
this International Standard to other applications as they deem appropriate.
