Full title and description

ISO 18885-3:2021 — TPMS snap-in valves — Part 3: Performances. This international standard specifies test methods for TPMS snap-in tubeless valves to determine the minimum level of performance required for those components in tyre pressure monitoring system applications.

Abstract

The document defines test methods and performance requirements for snap-in (tubeless) valves used with TPMS sensors, establishing minimum performance levels manufacturers and test laboratories should meet or verify. It is intended to ensure valve reliability and basic functional performance in service conditions.

Scope

This part of ISO 18885 applies to snap-in (tubeless) valves used with tyre pressure monitoring systems and specifies the test methods that determine the minimum performance levels required of those valves. It is written for use in passenger-vehicle TPMS applications and complements other parts of the ISO 18885 series that address identification and valve environment.

Key topics and requirements

• Definition of the types of snap-in tubeless valves covered and their intended TPMS application.
• Test methods to establish minimum acceptable performance (general framework and objectives rather than full product specifications).
• Typical test areas (commonly addressed in performance parts): pressure retention / leakage, valve retention/pull-out resistance, durability/cyclic fatigue, environmental and corrosion resistance, and functional sealing under service conditions.
• Requirements intended to support consistent verification by manufacturers and independent test laboratories.

Typical use and users

Primary users include TPMS valve manufacturers and component suppliers, tyre and wheel manufacturers, automotive OEM engineering and validation teams, independent testing and certification laboratories, and procurement/specification engineers who need to verify valve performance against an internationally recognised baseline.
