Freight containers -- Electronic seals -- Part 1: Communication protocol
The presentation of this information is provided through a radio-communications interface providing seal identification and a method for determining whether a freight container's seal has been opened.
ISO 18185-1:2007 specifies a read-only, non-reusable freight container seal identification system, with an associated system for verifying the accuracy of use, having
- a seal status identification system,
- a battery status indicator,
- a unique seal identifier including the identification of the manufacturer,
- seal (tag) type.
ISO 18185-1:2007 is used in conjunction with the other parts of ISO 18185.
It applies to all electronic seals used on freight containers covered by ISO 668, ISO 1496-1 to ISO 1496-5, and ISO 8323. Wherever appropriate and practicable, it also applies to freight containers other than those covered by these International Standards.
