SIST EN 60870-2-2:1997

Overview

EN 60870-2-2:1996 (adopted as SIST EN 60870-2-2:1997) is a European/IEC standard that defines the environmental operating conditions for telecontrol equipment and systems using coded bit serial data transmission. The standard applies to devices used for monitoring and control of geographically widespread processes, and it specifies classes of climatic, mechanical and other non-electrical influences under which telecontrol components must reliably operate.

Key Topics

The standard focuses on classification and guidance rather than device-level design details. Main technical topics include:

• Environmental classification: assignment of equipment to classes based on expected operating environments for telecontrol installations.
• Climatic influences: categories covering temperature ranges, humidity, condensation, and other atmospheric effects relevant to telecontrol gear.
• Mechanical influences: considerations such as vibration, shock and handling that can affect serial-data telecontrol equipment.
• Other non-electrical influences: exposure to dust, corrosive atmospheres, radiation and similar factors that impact long-term reliability.
• Scope of application: applicability to systems using coded bit serial data transmission for remote monitoring and control of distributed processes. Note: EN 60870-2-2 outlines environmental requirements and classes; designers and testers use these classifications to define test regimes and product specifications.

Applications

EN 60870-2-2 is intended for professionals and organizations involved in remote control and telemetry systems, including:

• Utility companies (electricity, water, gas) deploying remote terminal units (RTUs) and supervisory control and data acquisition (SCADA) equipment.
• Manufacturers of telecontrol hardware who need to specify environmental robustness for product lines.
• System integrators and network designers selecting equipment for geographically dispersed installations.
• Test laboratories and certification bodies applying environmental classes during compliance testing.
• Procurement teams and asset managers writing requirements for equipment exposed to harsh field conditions.

Related Standards

• Part of the EN/IEC 60870 family addressing telecontrol protocols and operating conditions. EN 60870-2-2 corresponds to IEC 870-2-2:1996.
• Adopted nationally (e.g., SIST EN 60870-2-2:1997) for local regulatory and procurement use. For implementation, users typically combine EN 60870-2-2 environmental classifications with protocol and electrical requirements from other documents in the EN/IEC 60870 series.
