Full title and description

ISO 1005-4:1986 — Railway rolling stock material — Part 4: Rolled or forged wheel centres for tyred wheels for tractive and trailing stock — Quality requirements. This International Standard specifies quality, material and manufacture requirements for rolled or forged wheel centres intended for fitting with tyres; the official PDF is available from ISO and from authorized standards distributors.

Abstract

Specifies requirements for the manufacture and supply of rolled or forged wheel centres for tractive and trailing stock which are suitable for tyring and are made of unalloyed steels in accordance with the standard's table and clauses. Spoked wheel centres are excluded. The part is intended to be used together with the general steel delivery requirements (see ISO 404).

Scope

Defines quality requirements for rolled or forged wheel centres intended for use with tyred wheels on tractive and trailing railway stock. The scope covers material selection (unalloyed steels specified by the standard), manufacturing form (rolled or forged), dimensional and quality characteristics required for subsequent tyring, and excludes spoked wheel centres. Where applicable, requirements of the general steel delivery standard (ISO 404) apply.

Key topics and requirements

• Material specification: permitted unalloyed steel grades and minimum chemical/mechanical requirements.
• Manufacture: acceptable production forms limited to rolled or forged wheel centres.
• Suitability for tyring: dimensional features and tolerances necessary for safe fitting of tyres.
• Quality checks: surface condition, dimensional tolerances, and inspection requirements prior to delivery.
• Exclusions and cross-references: spoked wheel centres excluded; general delivery and steel product requirements referenced to ISO 404.

These topics reflect the standard’s clauses on material, manufacture, inspection and cross-references to general steel delivery requirements.

Typical use and users

Used by railway rolling-stock manufacturers, wheel and axle subcontractors, metallurgical suppliers, procurement specialists in rail operators, and conformity/inspection bodies to specify, buy or verify rolled/forged wheel centres intended for tyre-fitting operations. National standards bodies and standards librarians also reference this part when compiling rail material requirements.

Related standards

Key related documents include ISO 404 (general technical delivery requirements for steel products) and other parts of the ISO 1005 series (e.g., parts covering tyres, wheel centres, axles, wheelsets and solid wheels). Users frequently consult the full ISO 1005 series for coordinated requirements across wheels, axles and wheelsets.

FAQ

Q: What is this standard?

A: ISO 1005-4:1986 is an International Standard that sets out quality requirements for rolled or forged wheel centres used with tyred wheels on tractive and trailing railway stock.

Q: What does it cover?

A: It covers material selection (unalloyed steels), acceptable manufacturing forms (rolled or forged), dimensional and surface quality requirements for wheel centres intended for tyring, and inspection/delivery considerations; spoked wheel centres are excluded. It also directs users to apply ISO 404 where general steel delivery requirements are relevant.

Q: Who typically uses it?

A: Railway manufacturers, wheel and axle producers, metallurgical suppliers, procurement and quality engineers in the rail sector, and conformity assessment organizations. Distributors of standards and national bodies also handle and sell the PDF and printed versions.

Q: Is it current or superseded?

A: According to the ISO catalogue entry the 1986 edition was reviewed and remains confirmed as current (last periodic confirmation recorded by ISO). Users should check the ISO catalogue or a national standards body for the most recent confirmation or any amendments before use.

Q: Is it part of a series?

A: Yes — ISO 1005 is a multipart series covering railway rolling stock material (tyres, wheel centres, axles, wheelsets and related items). ISO 1005-4 is Part 4 of that series. Consult the other parts of ISO 1005 for related requirements.

Q: What are the key keywords?

A: wheel centre, tyred wheel, rolled, forged, unalloyed steel, railway rolling stock, quality requirements, ISO 1005.
