Full title and description

ISO/IEC 30129:2015 — Information technology — Telecommunications bonding networks for buildings and other structures. This standard specifies requirements and recommendations for the design and installation of bonds (electrical connections) between conductive elements in buildings and other structures to protect telecommunications and IT equipment from electrical hazards and to provide a reliable signal reference for improved immunity to electromagnetic interference (EMI).

Abstract

ISO/IEC 30129:2015 provides design and installation guidance for telecommunications bonding networks used during construction or refurbishment of buildings and structures where IT and telecommunications equipment will be installed. The objective is to minimise risk to equipment and cabling from electrical hazards and to establish a consistent signal reference (bonding/earthing) to improve EMC/EMI performance. The published standard also has subsequent amendments that update or clarify specific clauses.

Scope

The standard covers requirements and recommendations for the design and installation of electrical bonds between various conductive elements in buildings and other structures when telecommunications or IT installations are planned. Topics include the arrangement of bonding networks, selection and sizing of bonding conductors and busbars, bonding to earth/ground systems, installation practices during construction and refurbishment, and measures to reduce the impact of electrical hazards and electromagnetic interference on telecommunications systems.

Key topics and requirements

• Definition and arrangement of telecommunications bonding networks for buildings and structures.
• Requirements for bonding components (conductors, busbars, connectors) and recommended minimum cross-sections for reliable connections.
• Interfaces between telecommunications bonding networks and building/main earthing systems to control potential differences and safety risks.
• Installation and routing guidance to minimise inductive/capacitive coupling and improve EMI immunity of cabling and equipment.
• Commissioning, testing and verification practices to ensure continuity and effectiveness of bonding installations.
• Guidance for application during new construction and refurbishment projects, including coordination with electrical and structural trades.
• Updates and clarifications introduced via published amendments (2019, 2025).

Typical use and users

Used by telecommunications and network designers, structured cabling engineers, electrical contractors, building services engineers, data centre planners, installation technicians, facility managers and consultants responsible for ensuring safe, EMC-aware telecommunications infrastructure in commercial, institutional and industrial buildings. The standard is applied during design, installation and commissioning stages of building projects.

Related standards

Commonly referenced alongside other cabling and grounding standards such as the ISO/IEC 11801 series (generic cabling for customer premises) and national/industry grounding and bonding standards (for example ANSI/TIA-607 series for commercial building bonding and grounding). It also complements electrical installation standards and regional building codes that govern earthing and safety.

FAQ

Q: What is this standard?

A: ISO/IEC 30129:2015 is an international standard that specifies requirements and recommendations for telecommunications bonding networks in buildings and other structures to protect IT and telecom equipment from electrical hazards and improve EMC/EMI performance.

Q: What does it cover?

A: It covers the design, selection and installation of bonds between conductive elements (conductors, busbars, connectors), their connections to building earthing systems, installation practices during construction/refurbishment, and testing/commissioning to ensure continuity and EMC performance. It does not replace electrical safety regulations but complements them for telecommunications infrastructure.

Q: Who typically uses it?

A: Network and cabling designers, electrical contractors, data center and facility engineers, telecom installation teams, and consultants involved in building infrastructure projects where IT or telecommunications systems will be installed.

Q: Is it current or superseded?

A: The original International Standard was published in October 2015 (Edition 1). It has at least two published amendments (Amendment 1 in 2019 and Amendment 2 in 2025) that update and clarify content; check the issuing bodies for the latest amendment status before relying on a printed copy.

Q: Is it part of a series?

A: ISO/IEC 30129 is a standalone standard focused on telecommunications bonding networks, but it is part of the broader ISO/IEC JTC 1/SC 25 portfolio relating to interconnection and cabling; it is commonly used together with series such as ISO/IEC 11801 (generic cabling).

Q: What are the key keywords?

A: Telecommunications bonding, bonding network, grounding/earthing, bonding conductor, bonding busbar, EMI, EMC, installation, commissioning, structured cabling.
