For the evaluation of the pass criterion set out in Table 5, the averages of the verification testing procedure ratio from the up to three tests shall be used. If the pass criterion is not reached, the vehicle fails the verification testing procedure.\nTable 5\nPass fail criterion for the verification test\nC VPT\nPass criterion for the verification testing procedure\n< 1,075",
