Scope

This Standard specifies laboratory test methods for verifying the capabilities of
tyres for passenger cars, including terms and definitions used in the tests,
testing equipment and precision, test conditions, testing procedures, judgment
criteria, and test reports. Of the test methods presented, it is possible that only
some will be required, depending on the type of tyre to be tested (tube or
tubeless, diagonal or radial).
This Standard includes.
(1) Bead unseating test. assesses the resistance of the tubeless tyre to bead
unseating.
(2) Strength test. assesses the capability of the tyre structure, with respect
to braking energy, in the tread area.
(3) High speed test. assesses the capability of the tyre according to its
speed category.
(4) Endurance test. assesses the resistance of the type, with respect to
service at specified load and speed.
(5) Low-pressure performance test. assesses reliability of radial tyres under
low pressure, with respect to service at specified load, speed, and low
pressure conditions.
The test methods presented in this Standard are not intended for gradation of
tyre performance or quality levels.
This Standard applies to all pneumatic-tyres for passenger cars.
