Scope and object
This section of IEC 870-2 applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and control of geographically widespread processes.
It is also a reference standard for teleprotection equipment and systems and for equipment included in a distribution line carrier (DLC) communication system supporting a distribution automation system (DAS) and also for associated communications such as power line carrier.
This section specifies classes for environmental conditions (climatic, mechanical and other non-electrical influences) under which the various components of the systems have to operate.
Particular conditions directly related to fire and explosion hazards and to ionizing radiation are not considered.
Detailed specifications for any other environmental conditions (including those related to mobile installations), not covered in this section but relevant for the proper operation and life of the equipment, are matters for negotiation between user and supplier.
