Overview
ISO 22074-1:2020 is an international standard developed by the International Organization for Standardization (ISO) that specifies the vocabulary and definitions related to railway infrastructure, specifically rail fastening systems. This document forms Part 1 of the ISO 22074 series and focuses on providing clear and standardized terminology used throughout the series for professionals working in the railway industry.
By establishing a consistent vocabulary, ISO 22074-1:2020 ensures better communication and understanding among engineers, designers, manufacturers, and maintenance teams involved with rail fastening systems. This is essential for enhancing the safety, performance, and interoperability of railway infrastructure worldwide.
Key Topics
The standard organizes terminology around several core categories, including:
Application of Standards
Defines categories of rail fastening systems based on parameters like curvature radius, axle load, rail profile, track gauge, and support spacing.Track Systems
Terms such as ballast track (where sleepers rest on ballast), structure types without ballast, and the various components like sleepers (ties or cross ties), supports, and bearing structures.Fastening Systems
Covers both direct and indirect rail fastening types, elastic and rigid fixation systems, and mechanisms acting on different parts of the rail (e.g., rail web or foot).Fastening Elements
Key components like rail clips, rail screws, seats (saddles), insulating pads (under rail or saddle), and adjustment shims.Fastener Characteristics
Definitions related to mechanical properties such as vertical, lateral, and lifting stiffness, static and dynamic stiffness, as well as vibration and noise attenuation capabilities of fastening systems.
This vocabulary enables precise classification and evaluation of rail fastening solutions, supporting standardized testing, design, and maintenance procedures.
Applications
ISO 22074-1:2020 is integral to the railway industry for the following practical purposes:
Railway Infrastructure Design
Ensures clear communication in the design of rail fastening systems, allowing engineers to select appropriate fasteners that meet track conditions and performance requirements.Manufacturing and Quality Control
Provides manufacturers with standardized terminology that ensures consistency across product specifications and compliance with international norms.Testing and Evaluation
Supports testing laboratories by defining reference surfaces, load application methods, and stiffness parameters critical for quality assurance and certification.Maintenance and Inspection
Assists maintenance teams in identifying and describing components accurately, facilitating efficient inspection, replacement, and troubleshooting operations.Training and Documentation
Acts as a foundational reference text for training railway professionals and compiling comprehensive technical manuals or regulatory documents.
Through these applications, ISO 22074-1:2020 contributes to enhancing track stability, rail longevity, and overall railway safety.
Related Standards
ISO 22074-1:2020 is part of the broader ISO 22074 series dedicated to rail fastening systems. Related standards include multiple parts that cover specific requirements, test methods, and performance criteria of fastening components and systems.
In addition, this vocabulary standard harmonizes with other railway infrastructure standards such as:
ISO TC 269 (Railway Applications) technical committee publications, which address broader railway systems and infrastructure.
IEC Electropedia and ISO Online Browsing Platform, which are referenced for maintaining internationally aligned terminology databases.
Consulting the full ISO 22074 series along with complementary ISO railway standards ensures a comprehensive understanding and implementation of best practices in railway fastening and infrastructure.
