This specification contains the general requirements for the 245/7OR19.5 136/134M radial truck standard reference test. Provided in this specification is a 19.5 rim diameter code standard truck design and construction, standard dimensions, and standard conditions of storage. A reference tire is covered in this specification for braking traction, snow traction, wear evaluations pavement roughness, noise and other forms of test requiring a reference tire. Test methods of the tensile sheet cure, the 300% stress elongation, and tensile sheet strength should be in accordance to the specified testing requirements presented in D3182, and D412. The testing procedure also includes using of Type A durometer centred at the presser foot at a minimum of 6.0 mm, chaking the durometer operation and the state of durometer calibration with rubber reference, determining tire tread hardness by four readings and quickly applying the presser foot to the tire tread without inducing shock.
