BS AU 50-1.0.1 specifies test methods carried out under controlled conditions for verifying the uniformity of tyres for passenger cars, commercial vehicles and motorcycles.
Methods for measuring the geometrical run-out of the tyre in both radial and lateral directions are covered, as well as methods for measuring the following parameters:
Not all of these measurements will necessarily be relevant in every situation.
BS AU 50-1.0.1 does not include methods for measuring the static and the dynamic unbalance nor methods related to tyre-wheel assemblies.
The test methods specified in BS AU 50-1.0.1 are not intended for the gradation of tyres or the definition of quality levels.
BS 5173 -106.2 on methods of testing tyres is for:
Uniformity is the state in which any characteristic of the tyre is constant in phase and magnitude in both static and dynamic conditions around the circumference.
BS AU 50-1.0.1 provides procedures and methods for testing and measuring tyre uniormity.
BS AU 50-1.0.1 specifies requirements and measurements for tyre testing such as tolerance, durability and strength ensuring tyre safety.
BS AU 50-1.0.1 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The test methodologies given in BS AU 50-1.0.1 enable you to examine the tyres for any signs of deformation or delamination of reinforcement or lining, which contributes a lot to maintaining the high quality and efficient functioning of retarded tyres.
