ISO 14960-1:2023

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.
