alternative test method is a machine/rig base test in which braking force is measured and, from which,
braking performance values are calculated. The progressive characteristics of the brake are determined
by linearity measurements. A final, simple track test checks for smooth, safe, stopping characteristics.
Whichever method is used, there shall be compliance with 4.6.8.1.1 or 4.6.8.1.2.
NOTE See TBIS 4210-4:2017, 4.6.5.7 item h), test method — simple track test.
