Full title and description

St ISO 22752-2021 — Railway applications — Bodyside windows for rolling stock. This international standard specifies classification, technical requirements and marking for bodyside glazing assemblies fitted to the sides of railway vehicles, covering standard fixed and movable windows and emergency windows (escape and access). It addresses glazing materials and their associated mounting arrangements for all types of railway vehicles except on‑track machines.

Abstract

ISO 22752:2021 defines types of bodyside windows used on rolling stock and sets out minimum technical requirements, tests and marking information for standard windows (fixed and movable) and emergency windows (escape and access). The document applies to glazing and its mounting arrangements for windows mounted on the sides of passenger and service areas of railway vehicles, including heavy rail and urban rail, and excludes on‑track machines. It supports safe evacuation and operational durability of window assemblies in service conditions.

Scope

This standard applies to bodyside windows constructed from glazing materials only and to the glazing together with its associated mounting arrangement. It covers classification, technical requirements, marking and testing requirements for standard fixed and movable windows and for emergency windows (escape and access). The scope includes windows fitted to saloons, restaurant/buffet cars, vestibules, toilets, driving cabs, crew compartments and technical rooms on all types of railway vehicles (heavy and urban), but explicitly excludes windows for on‑track machines.

Key topics and requirements

• Classification of bodyside windows: standard fixed, standard movable, emergency escape and emergency access windows.
• Technical requirements for glazing materials (mechanical strength, impact, optical properties and fire/safety characteristics as applicable).
• Requirements for mounting arrangements and interfaces between glazing and vehicle body.
• Marking and identification requirements for window type and emergency function.
• Performance and test criteria to demonstrate compliance under normal and emergency conditions.
• Applicability matrix identifying vehicle types and locations where the standard applies and explicit exclusions (on‑track machines).

Typical use and users

Users of ISO 22752:2021 include rolling stock designers and engineers, window and glazing manufacturers, vehicle system integrators, railway operators, safety and certification bodies, testing laboratories and procurement teams specifying window assemblies for new vehicles or refurbishment projects. The standard is used to define technical specifications, acceptance tests and marking requirements for bodyside windows to ensure safety, maintainability and interoperability.

Related standards

ISO 22752 sits within the suite of railway‑vehicle standards developed under ISO/TC 269. It is commonly used alongside other national and international regulations and standards addressing rolling stock safety, glazing performance and vehicle interior fittings. Relevant complementary documents include other ISO standards for rolling stock components and regional railway technical specifications and glazing safety standards employed by manufacturers and authorities.
