本SAE推荐规程定义了评估峰值和锁定车轮制动牵引力的最著名技术。它涵盖了轮胎制动牵引力的一个重要阶段，即潮湿或干燥的路面直行条件。然而，这只是整个轮胎牵引力领域的一小部分。随着本复杂研究其他阶段的测试程序的建立，将编写额外的补充程序。本推荐规程附录B中包含了对整个主题的讨论。

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.
