Appendix E to Subpart S of Part 51 - Transient Test Driving Cycle

(I) Driver's trace. All excursions in the transient driving cycle shall be evaluated by the procedures defined in § 86.115-78(b)(1) and § 86.115(c) of this chapter. Excursions exceeding these limits shall cause a test to be void. In addition, provisions shall be available to utilize cycle validation criteria, as described in § 86.1341-90 of this chapter, for trace speed versus actual speed as a means to determine a valid test.

(II) Driving cycle. The following table shows the time speed relationship for the transient IM240 test procedure.
