ISO 14960-1:2023 PDF

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
