Overview

The SIST EN 50085-1:2006/A1:2013 standard, published by the European Committee for Electrotechnical Standardization (CENELEC), defines the general requirements for cable trunking systems (CTS) and cable ducting systems (CDS) used in electrical installations. This amendment to the 2005 edition was approved to ensure harmonized safety, performance, and durability of cable management systems across Europe.

This standard establishes essential criteria concerning mechanical strength, safety against fire propagation, electrical protection, environmental resistance, and proper system marking to facilitate reliable electrical infrastructure installations.

Key Topics

• Scope and Application: Applies to all types of cable management systems designed for electrical installations within regulated voltage limits, supporting safe routing, protection, and segregation of electrical cables.

• Mechanical Impact Resistance: Classification of CTS/CDS by resistance to impact ranging from 0.5 J to 20 J, ensuring systems endure physical stresses during installation, transport, and operational use.

• Fire Safety Requirements: Defines non-flame propagating system components that either do not ignite or self-extinguish once an applied flame is removed, reducing fire hazard and supporting overall electrical safety.

• Marking and Documentation: Mandates clear product identification, including manufacturer information and flame propagation properties, on components or their packaging. Uses recognized IEC 60417 symbols for current, voltage, frequency, and protection to standardize labelling.

• Protection and Durability: Addresses protection against ingress of solids/liquids, corrosion, and mechanical stress. Details environmental temperature tolerances and aging tests to verify system robustness.

• System Access and Cover Retention: Specifies that access covers must not be removable without tools when classified for certain protection levels-tested after aging at specified temperatures to simulate operational conditions.

• Testing and Compliance: Includes impact testing procedures, fixing tests for apparatus mounting, and system accessibility evaluations to verify adherence to standard requirements.

Applications

This standard is crucial for electrical engineers, contractors, and manufacturers involved in:

• Designing and installing cable trunking and ducting systems in commercial, industrial, and residential electrical projects.
• Ensuring electrical installation safety by adopting non-flame propagating cable management products.
• Enhancing mechanical protection of electrical cables against environmental and operational damage.
• Selecting compliant cable management systems that meet European regulatory requirements, supporting CE marking and national standard alignment.
• Facilitating best practices in cable routing, maintenance accessibility, and system identification to improve installation quality and lifecycle management.

Using SIST EN 50085-1:2006/A1:2013-compliant products reduces risks related to fire propagation, mechanical failure, and accidental contact with live parts, thereby enhancing electrical installation reliability and safety.

Related Standards

• EN 62262 (IEC 62262): Degrees of protection against mechanical impacts for electrical equipment enclosures (IK code), referenced for impact resistance testing.
• EN 60529: Degrees of protection provided by enclosures (IP Code), relevant for assessing ingress protection of trunking and ducting.
• IEC 60417: Graphical symbols for use on equipment, applicable for standardized marking symbols on cable management components.
• Low Voltage Directive (LVD) 2006/95/EC: Regulatory framework ensuring electrical equipment safety within set voltage limits, directly supported by compliance with this standard.
