Full title and description

Railway rolling stock material — Part 9: Axles for tractive and trailing stock — Dimensional requirements. Specifies dimensional requirements and surface roughnesses for axles used on tractive and trailing railway stock; certain requirements for heavy freight vehicle axles or axles for speeds under 100 kg/h are to be agreed between purchaser and manufacturer.

Abstract

Defines the dimensional characteristics, tolerances and surface finish requirements for axles intended for tractive and trailing railway vehicles. Notes that the general technical delivery requirements of ISO 404 apply and that special cases (e.g., heavy freight or low‑speed axles) require purchaser–manufacturer agreement.

Scope

This part of ISO 1005 specifies the dimensional requirements (including tolerances and key dimensions) and the surface roughness criteria for axles used on tractive and trailing railway stock. It complements the general technical delivery requirements given in ISO 404. Where axles are intended for heavy freight vehicles or for services below a specified operational speed (noted as a special case), the applicable requirements are to be agreed between purchaser and manufacturer at enquiry and order stages.

Key topics and requirements

• Specified axle dimensions and associated tolerances for tractive and trailing stock.
• Surface roughness requirements for axle journals and bearing seats.
• Reference to general technical delivery requirements (ISO 404) for material and delivery conditions.
• Rules for handling special cases (heavy freight vehicle axles and low‑speed axles) requiring purchaser–manufacturer agreement.
• Applicable dimensional inspection and verification practices implied by the specified tolerances and finishes.

Typical use and users

Used by railway vehicle manufacturers, axle and wheelset producers, component designers, procurement teams specifying axle requirements, quality and inspection laboratories, and maintenance organizations. Also referenced by standards committees and conformity assessment bodies involved in railway rolling stock material specifications.

Related standards

Part of the ISO 1005 series covering railway rolling stock material (other parts address wheel centres, wheelsets and quality requirements). ISO 404 is referenced for general technical delivery requirements. Other ISO 1005 parts (for example parts 1–8 and related items in the series) provide complementary dimensional and quality rules for wheels, wheel centres and wheelsets.

FAQ

Q: What is this standard?

A: ISO 1005-9:1986 is an international standard that specifies dimensional and surface‑finish requirements for axles used on tractive and trailing railway vehicles.

Q: What does it cover?

A: It covers key axle dimensions, tolerances and surface roughness criteria, and refers to ISO 404 for general technical delivery requirements; special cases (heavy freight or low‑speed axles) are handled by agreement between purchaser and manufacturer.

Q: Who typically uses it?

A: Manufacturers of railway axles and wheelsets, vehicle builders, procurement and engineering teams, testing and inspection labs, and maintenance organizations within the rail industry.

Q: Is it current or superseded?

A: The 1986 edition (Edition 1) remains the published document and has been subject to periodic review; the ISO record indicates the standard was reviewed and confirmed in recent systematic reviews, so this edition remains current unless formally withdrawn or replaced by a later publication.

Q: Is it part of a series?

A: Yes — it is part 9 of the ISO 1005 series (railway rolling stock material). Other parts of ISO 1005 address wheel centres, wheelsets and related quality and dimensional requirements.

Q: What are the key keywords?

A: Axles, railway rolling stock, dimensional requirements, surface roughness, tolerances, wheelsets, ISO 1005, ISO 404.
