This SAE Recommended Practice defines the best known techniques for evaluating peak and locked wheel braking traction. It covers an important phase of tire braking traction, namely, the wet or dry pavement straight ahead conditions. However, this is but a small portion of the whole field of tire traction. As test procedures are established for other phases of this complex study, additional supplementary procedures will be written. A discussion of this entire subject is contained in Appendix B to this recommended practice.
This technical report is being stabilized because other standards exist which are being used widely by regulators and other industry stakeholders. Because all users of this standard cannot be identified, the committee recommends stabilization at this time.
