This part of ISO 18185 specifies the minimum environmental characteristics for electronic seals. This part of ISO 18185 describes the environmental requirements for the ISO 18185 series, for ISO 10374 (Freight containers — RF automatic identification) and for ISO 17363 (Supply chain applications of RFID — Freight containers), since it is expected that the implementation of these International Standards will face the same environmental conditions. However, each of these International Standards has its own unique requirements other than environmental conditions.
