§ 86.000-26
Section 86.000-26 includes text that specifies requirements that differ from § 86.094-26, § 86.095-26, § 86.096-26 or § 86.098-26. Where a paragraph in § 86.094-26, § 86.095-26, § 86.096-26 or § 86.098-26 is identical and applicable to § 86.000-26, this may be indicated by specifying the corresponding paragraph and the statement “[Reserved]. For guidance see § 86.094-26.” or “[Reserved]. For guidance see § 86.095-26.” or “[Reserved]. For guidance see § 86.096-26.” or “[Reserved]. For guidance see § 86.098-26.”
[Reserved]. For guidance see § 86.094-26.
The standard method of whole-vehicle service accumulation for durability data vehicles and for emission data vehicles shall be mileage accumulation using the Durability Driving Schedule as specified in appendix IV to this part. A modified procedure may also be used if approved in advance by the Administrator. Except with the advance approval of the Administrator, all vehicles will accumulate mileage at a measured curb weight which is within 100 pounds of the estimated curb weight. If the loaded vehicle weight is within 100 pounds of being included in the next higher inertia weight class as specified in § 86.129, the manufacturer may elect to conduct the respective emission tests at higher loaded vehicle weight.
Emission data vehicles.
Unless otherwise provided for in § 86.000-23(a), emission-data vehicles shall be operated and tested as described in paragraph (a)(3)(i)(A) of this section; § 86.094-26(a)(3)(i)(B) and (D), § 86.098-26(a)(3)(i)(C) and (a)(3)(ii)(C), and § 86.094-26(a)(3)(ii) (A), (B) and (D).
The manufacturer shall determine, for each engine family, the mileage at which the engine-system combination is stabilized for emission-data testing. The manufacturer shall maintain, and provide to the Administrator if requested, a record of the rationale used in making this determination. The manufacturer may elect to accumulate 4,000 miles on each test vehicle within an engine family without making a determination. The manufacturer must accumulate a minimum of 2,000 miles (3,219 kilometers) on each test vehicle within an engine family. All test vehicle mileage must be accurately determined, recorded, and reported to the Administrator. Any vehicle used to represent emission-data vehicle selections under § 86.000-24(b)(1) shall be equipped with an engine and emission control system that has accumulated the mileage the manufacturer chose to accumulate on the test vehicle. Fuel economy data generated from certification vehicles selected in accordance with § 86.000-24(b)(1) with engine-system combinations that have accumulated more than 10,000 kilometers (6,200 miles) shall be factored in accordance with 40 CFR 600.006-87(c). Complete exhaust (FTP and SFTP tests), evaporative and refueling (if required) emission tests shall be conducted for each emission-data vehicle selection under § 86.000-24(b)(1). The Administrator may determine under § 86.000-24(f) that no testing is required.
(B) [Reserved]. For guidance see § 86.094-26.
(C) [Reserved]. For guidance see § 86.098-26.
(D)-(a)(3)(ii)(B) [Reserved]. For guidance see § 86.094-26.
(D)-(a)(4)(i)(B)(4) [Reserved]. For guidance see § 86.094-26.
(C) Complete exhaust emission tests shall be made at nominal test point mileage intervals that the manufacturer determines. Unless the Administrator approves a manufacturer's request to develop specific deterioration factors for aggressive driving (US06) and air conditioning (SC03) test cycle results, tail pipe exhaust emission deterioration factors are determined from only FTP test cycle data. At a minimum, two complete exhaust emission tests shall be made. The first test shall be made at a distance not greater than 6,250 miles. The last shall be made at the mileage accumulation endpoint determined in § 86.094-26 (a)(4)(i) (A) or (B), whichever is applicable.
(D)-(a)(6)(ii) [Reserved]. For guidance see § 86.094-26.
The results of all emission tests shall be rounded to the number of places to the right of the decimal point indicated by expressing the applicable emission standard of this subpart to one additional significant figure, in accordance with the Rounding-Off Method specified in ASTM E29-90, Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications (incorporated by reference; see § 86.1).
-(a)(9)(i) [Reserved]. For guidance see § 86.094-26.
The test procedures in §§ 86.106 through 86.149 and § 86.158 will be followed by the Administrator. The Administrator may test the vehicles at each test point. Maintenance may be performed by the manufacturer under such conditions as the Administrator may prescribe.
-(b)(2) introductory text [Reserved]. For guidance see § 86.094-26.
This paragraph (b)(2)(i) applies to service accumulation conducted under the Standard Self-Approval Durability Program of § 86.094-13(f). The manufacturer determines the form and extent of this service accumulation, consistent with good engineering practice, and describes it in the application for certification. Service accumulation under the Standard Self-Approval Durability Program is conducted on vehicles, engines, subsystems, or components selected by the manufacturer under § 86.000-24(c)(2)(i).
This paragraph (b)(2)(ii) applies to service accumulation conducted under the Alternative Service Accumulation Durability Program of § 86.094-13(e). The service accumulation method is developed by the manufacturer to be consistent with good engineering practice and to accurately predict the deterioration of the vehicle's emissions in actual use over its full useful life. The method is subject to advance approval by the Administrator and to verification by an in-use verification program conducted by the manufacturer under § 86.094-13(e)(5).
-(b)(4)(i)(C) [Reserved]. For guidance see § 86.094-26.
(D)-(b)(4)(ii)(D) [Reserved]. For guidance see § 86.095-26.
-(c)(3) [Reserved]. For guidance see § 86.094-26.
[Reserved]. For guidance see § 86.096-26.
introductory text through (d)(2)(i) [Reserved]. For guidance see § 86.094-26.
The results of all emission tests shall be recorded and reported to the Administrator. These test results shall be rounded, in accordance with the Rounding-Off Method specified in ASTM E29-90, Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications (incorporated by reference; see § 86.1), to the number of decimal places contained in the applicable emission standard expressed to one additional significant figure.
-(d)(6) [Reserved]. For guidance see § 86.094-26.
