Description / Abstract:
This document establishes best practices to measure vehicle
stopping distance on dry asphalt in a straight path of travel
intended for the purpose of publishing stopping distance by
manufacturers and media organizations. It is recommended that the
test method within be adopted for all vehicles less than 10 000 lb
(4536 kg) GVWR. This procedure is typically used with initial
speeds of 100 km/h and 60 mph, but other speeds may be used.
Purpose
This vehicle stopping distance procedure outlines methodology to
provide consistent results within a test facility or test site,
using best known practices including standards for test equipment,
vehicle and tire guideline preparation, and dry asphalt surface
friction compensation.
