Overview

ISO 14960-1:2023 - "Tubeless tyres - Valves and components - Part 1: Snap-in tyre valves test methods" specifies laboratory test methods and performance requirements for snap-in tubeless tyre valves intended primarily for on‑road applications. The document defines how to prepare, age and test valves (excluding TPMS valves and high‑pressure valves), and provides reproducible procedures to assess sealing, mechanical and environmental resistance.

Key Topics

• Scope & definitions
  • Applies to snap‑in valves (rigid housing adhered to a resilient body).
  • Excludes TPMS and high‑pressure valves.
  • Defines "unused" and "aged" valve conditions (ageing example: 100 °C ±3 °C for 4 h, then cooled).
• Test fixtures & hole sizes
  • Test plate/hole diameters included: 8.8 mm, 11.3 mm and 15.7 mm with specified thickness and edge chamfering.
• Primary test methods
  • Adhesion: axial cuts and traction to measure bond separation.
  • Valve core seal: room temperature, low temperature (–40 °C) and high temperature (100 °C) leak tests with defined pressures; acceptable leakage < 0.2 cm3/min or no bubble for 1 min.
  • Valve cap seal (optional for sealing caps).
  • Valve-to-rim seal: low and high temperature sealing checks using the specified fixtures.
  • Installation tests: force to seat and force to pull out; wet installation with water lubricant and seating indicator ring criteria.
  • Burst and flexing resistance: pressure/burst protocols and flex cycling.
  • Ozone resistance and other resistance tests: valve core torque resistance, valve core cycling, valve nose resistance.
• Measured parameters
  • Valve core pin position: +0.25 mm to −0.90 mm.
  • Standard torque ranges: 0.34–0.56 Nm (metallic sealing), 0.23–0.56 Nm (non‑metallic gasket).
  • All pressures are gauge pressures.

Applications / Who uses it

• Valve manufacturers: design validation, production qualification and supplier specifications.
• Tyre, rim and wheel manufacturers / OEMs: confirm compatibility and sealing performance for tubeless systems.
• Independent test laboratories: standardized procedures for certification and quality control.
• Quality assurance and procurement teams: acceptance testing and supplier audits.
• Regulatory bodies and fleet operators: harmonized test evidence for safety and reliability claims.

Related Standards

• ISO 9413 - Tyre valves: dimensions and designation.
• ISO 3877-2 - Tyres, valves and tubes: list of equivalent terms (Part 2: Tyre valves).
• Part of the broader ISO 14960 series on valves and components.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

revised.
The main changes are as follows:
— all test methods have been revised;
— test methods have been added for valve hole with diameter 8,8 mm;
— resistance tests have been added.

4 Methods for testing tubeless tyres snap-in valves
4.1 General
All the pressures mentioned in the testing procedures are gauge pressures.
A tested snap-in valve shall be a unit free of rubber in the air passage, no rubber or cement above the
second thread on the housing, and without flow cracks, blisters, voids, or other moulding defects. The
mould parting line flash if present should not influence the test execution.
4.2 Ageing
If nothing specified, each of the following tests shall be considered on unused valves.
For the purpose of this testing method, aged valves are those unused valves that have been subjected to
100 °C ± 3 °C for 4 h in circulating hot air and then cooled at 23 °C ± 5 °C a minimum of 4 h.
Other ageing profile should be considered regarding the real-life case. The definition of other ageing
profile shall be agreed between the customer and the valve manufacturer.
4.3 Test fixtures
Break both edges on both sides of the valve hole either by a 45° chamfer or a radius from 0,3 mm to
0,4 mm. Emery cloth or suitable tooling is recommended. It is recommended that material of the test
fixture be representative of the material of the actual rim.
The primary external seal of a “snap-in” valve in a valve hole is obtained from the rubber compression
of the valve body onto the internal surface of the valve hole. Secondary external sealing may be present
by the contact of the remainder of the valve body exterior to the surface of the material around the
val
