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 documentsdocument 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).

Tubeless tyres — Valves and components —
Part 1:
Snap-in tyre valves test methods
1 Scope
This document specifies test methods for snap-in tubeless tyre valves intended for, but are not limited to,
on-road applications. TPMS valves and high-pressure valves are not included in this document.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 9413, Tyre valves — Dimensions and designation
3 Terms and definitions
For the purposes of this document, the terms, definitions and designations given in ISO 3877--2 and,
ISO 9413 and the following apply.

snap-in valve
tyre valve having a rigid housing adhered to a resilient body designed to retain and seal the valve in the
rim hole

valve that has completed final curing processing at least 24 h previously, that has not been subjected to
any test or service and that has been stored for no longer than four months in the dark at an ambient
temperature between 18 °C and 28 °C, in an optimal and non-aggressive environment

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 valve
hole. Either of both of these seals can be affected by the compound curvatures in the wheel rims and by
stock thickness.
The hole diameter and thickness for the considered test is specified in Table 1.Table 1.
