ISO 10475-1992 PDF

Full title and description

ISO 10475:1992 — Valves for tubeless tyres and valves for tubes — Identification system for valves and their components. The standard defines a concise coding system to identify types of tyre valves and the principal components used with them (codes for valves and separate codes for valve components).

Abstract

Provides an identification system in which valves are given a four‑character code (two letters followed by two digits) and valve components are given a three‑character code (one letter followed by two digits). Intended to standardize designation and reduce ambiguity between manufacturers, users and standards bodies.

Key bibliographic and status details as shown in ISO and national catalogues. The ISO record indicates the document has been withdrawn and subsequently revised by ISO 9413:1998. National standards catalogues list the original publication date and show the document as no longer current.

Scope

Specifies an identification system (coding scheme) for valves used with tubeless tyres and for valves used with inner tubes, and for their components. The scope is limited to nomenclature and identification coding (format and structure of codes) rather than dimensional specifications or performance requirements. It was intended for use by manufacturers, suppliers and standards committees to label and reference valve types and parts unambiguously.

Key topics and requirements

• Definition of a four‑character valve identification code: two letters + two digits for valve types.
• Definition of a three‑character component code: one letter + two digits for valve components.
• Rules for constructing and interpreting identification codes to ensure consistency across suppliers and documentation.
• Scope limited to identification; does not specify dimensions, pressure ratings or installation torque (those are covered by other related standards).

Typical use and users

Used historically by valve manufacturers, tyre and wheel manufacturers, component suppliers, aftermarket parts distributors, standards committees and technical libraries to standardize references to valve types and spare components. Applications included product catalogs, parts lists, procurement documents and cross‑reference tables. Regulatory or dimensional requirements for valves would be handled by complementary standards.

Related standards

ISO 10475:1992 was later superseded and its subject matter incorporated into subsequent standards; ISO lists ISO 9413:1998 as the revising document. National adoptions and identical publications (for example PN/ISO or national catalog entries) and national tyre/wheel standards reference or align with the identification approach given here. Complementary standards cover dimensions, performance and installation requirements for tyre valves.

FAQ

Q: What is this standard?

A: ISO 10475:1992 is an ISO International Standard that defined a short identification (coding) system for valves used on tubeless tyres and for valves used with tubes, and for valve components. It focused on labels/codes rather than dimensional or performance specifications.

Q: What does it cover?

A: It covers the structure and rules of an identification system: valves are assigned a four‑character code (two letters + two digits) and valve components a three‑character code (one letter + two digits). It does not set dimensional tolerances or performance tests.

Q: Who typically uses it?

A: Manufacturers and suppliers of tyre valves and valve components, tyre and wheel manufacturers, aftermarket parts distributors, standards committees and technical librarians — anyone who needs a concise, standard way to reference valve types and parts in documentation and catalogs.

Q: Is it current or superseded?

A: ISO 10475:1992 has been withdrawn/superseded; ISO indicates it has been revised by ISO 9413:1998. Many national catalogues also mark 10475:1992 as no longer in force. For current requirements you should consult the superseding standard(s) and the ISO catalogue.

Q: Is it part of a series?

A: It was developed within ISO/TC 31 (and subcommittee SC 9) activities related to tyres, rims and valves; related documents address dimensions, performance and safety aspects of tyre valves and tyre/wheel assemblies.

Q: What are the key keywords?

A: Tyre valve, tubeless valve, valve components, identification code, valve nomenclature, ISO 10475, tyre accessories.
