Full title and description

ISO 1005-2:1986 — Railway rolling stock material — Part 2: Tyres, wheel centres and tyred wheels for tractive and trailing stock — Dimensional, balancing and assembly requirements. This part of ISO 1005 specifies dimensional requirements, surface roughness and permissible residual static unbalance for tyres, wheel centres and tyred wheels, together with manufacturing requirements for tyred wheels.

Abstract

Defines dimensional tolerances, form/run-out tolerances, surface-finish requirements and — where appropriate — permissible residual static unbalance for railway tyres, wheel centres and assembled tyred wheels in different degrees of finish. It cross-references quality and technical delivery requirements given in related parts of ISO 1005 and in ISO 404.

Scope

This part of ISO 1005 applies to tyres, wheel centres and tyred wheels for both tractive and trailing railway stock. It specifies the dimensional requirements (including tolerances and run‑out limits), surface roughness values for specified degrees of finish, permissible residual static unbalance for finished wheels (where applicable), and the manufacturing/assembly requirements relevant to tyred wheels. The standard also defines purchaser-supplied information (for example, degree of finish and operating speed regime) required when ordering wheels or components.

Key topics and requirements

• Dimensional tolerances for tyres, wheel centres and assembled tyred wheels (form, orientation, location and run‑out).
• Surface roughness parameters and values for different degrees of finish.
• Permissible residual static unbalance limits for wheels depending on speed regime and wheel type.
• Manufacturing and assembly requirements specific to tyred wheels (press‑fitting, fitting tolerances, assembly checks).
• Information the purchaser must supply (drawings, degree of finish, speed regime, any deviations from standard values).
• Cross-references to related delivery and quality standards (ISO 1005 parts, ISO 404, ISO 468, ISO 1101, etc.).

Typical use and users

Used by railway vehicle manufacturers, wheel and tyre producers, heat-treatment and forging suppliers, maintenance and refurbishment facilities, procurement and specification engineers, and testing/inspection organizations involved in wheelset manufacture, assembly and acceptance testing. The standard supports design, production control, quality assurance and contractual specifications for rolling‑stock wheel components.

FAQ

Q: What is this standard?

A: ISO 1005-2:1986 is an ISO International Standard that specifies dimensional, surface‑finish, balancing and assembly requirements for tyres, wheel centres and tyred wheels used on tractive and trailing railway stock.

Q: What does it cover?

A: It covers form and run‑out tolerances, dimensional limits, surface roughness values for different degrees of finish, permissible residual static unbalance (where applicable), manufacturing/assembly requirements for tyred wheels, and purchaser information needed to place orders.

Q: Who typically uses it?

A: Wheel and tyre manufacturers, railway vehicle OEMs, maintenance and wheel‑refurbishment shops, procurement/specification engineers and inspection laboratories involved in production and acceptance of railway wheels and wheel components.

Q: Is it current or superseded?

A: As of the latest ISO bibliographic record, ISO 1005-2:1986 remains published and has been periodically reviewed and reconfirmed (the ISO record shows confirmation actions including reconfirmation on 21 February 2024). It is not shown as superseded. Users should check the ISO catalog or their national standards body for the absolute latest status before relying on it for new procurements.

Q: Is it part of a series?

A: Yes — ISO 1005 is a multipart series covering railway rolling stock material (multiple parts addressing tyres, wheel centres, axles, wheelsets, solid wheels and related quality/delivery conditions). ISO 1005-2 is one part of that broader series.

Q: What are the key keywords?

A: Tyres, wheel centres, tyred wheels, railway rolling stock, dimensional requirements, balancing, surface roughness, static unbalance, assembly, ISO 1005.
