Note: This appendix shows the entirety of regulatory amendments to the test

procedures titled below, which were approved by the Air Resources Board on

December 16, 2011, and refined via subsequent conforming modifications

authorized under Resolution 11

- 41. I ncorporate d by reference into these test

procedures are portions of Title 40 of the Code of Federal Regulations (CFR)

Part 1065

– Engine

- Testing Procedures, Subparts A through K inclusive, as

amended June 28, 2011 ; and, the internally referenced sections of Title

40 CFR, Parts 60, 80, 86, 90, 1054, and 1068

. Sections tha t have been

included in their entirety are set forth with the section number and title.

California provisions that replace specific federal language provisions are

denoted by the words “DELETE” for the federal language and “REPLACE

WITH” or “ADD” for the California language. The notation [ * * * * * ] or

[

... ] mean s that the remainder of the CFR text for a specific section is not

shown in these procedures but has been incorporated by reference, with only

the printed text changed. CFR sections t hat are not listed are not part of

California’s test procedures. If there is any conflict between the provisions of

this document and the California Health and Safety Code, Division 26, or Title

13 of the California Code of Regulations (CCR), the Health a nd Safety Code

and Title 13 apply.

(a) DELETE,

REPLACE WITH:

(a) Certification test fuel.

(1) The certification test fuel used for emission testing must be consistent with

the fuel specifications as outlined in t he California Code of Regulations, title 13,

§1960.1, and the “California Exhaust Emission Standards and Test Procedures for 2001

– 2014 Model Passenger Cars, Light Duty Trucks, and Medium

- Duty Vehicles”, as last

amended [insert latest amendment date], and as incorporated by reference herein. The

test fuel specification should remain consistent from batch to batch. If a particular

engine requires a different octane fuel, test records should indicate the fuel used.

(2) For 2020 and later gasoline

- fueled engines: The certification test fuel for

emission testing must be consistent with the fuel specifications as outlined in title 13,

section 1961.2 and the “California 2015 and Subsequent Model Criteria Pollutant

Exhaust Emission Standards and Test Procedur es and 2017 and Subsequent Model

Greenhouse Gas Exhaust Emission Standards and Test Procedures for Passenger

Cars, Light

- Duty Trucks, and Medium

- Duty Vehicles,” adopted [insert adoption date],

and incorporated by reference herein. The test fuel specificat ions must remain

consistent from batch to batch. Optionally, manufacturers may use other renewable fuel

blends under this paragraph that have been certified by ARB as yielding test results

equivalent, or more stringent than, those resulting from the fuel specified by 13 CCR

1961.2, and which are appropriate for the certification of small off

- road engines.

(3) For 2013

– 2019 model

- year gasoline

- fueled engines, the manufacturer has

the option to use the certification test fuel specified in §1065.701(a)(2)

.

(4) Alcohol

- based fuels. Alcohol

- based fuels must be allowed for emission test

purposes when the appropriate emission standards with respect to such fuels are a part

of these provisions. Such fuels must be as specified in either §1065.701(a)(1) or

§ 1065.701(a)(2), as applicable.

(b) DELETE,

With Executive Officer approval, the certifying entity may use other test fuels so long as

they do not affect the demonstration of compliance.18 * * * * *

(f) DELETE,

REPLACE WITH:

(f) T est fuels

– service accumulation and aging.

through retail outlets must be used in service accumulation and aging for gasoline

fueled, spark ignition engines. As an alternative, the certification test fuels specified

under either §1054.501(b)(2)(ii)(A) or §1054.501(b)(2)(ii)(B), as applicable, may be used

for engine service accumulation and aging.

(ii) The octane rating of the gasoline used for service accumulat ion and

aging must be no higher than 4.0 Research Octane Numbers above the minimum

recommended by the engine manufacturer when a certification fuel is not used for

service accumulation, and must have a minimum sensitivity of 7.5 Octane Numbers.

Sensitivit y is the Research Octane Number minus the Motor Octane Number.

(iii) The Reid Vapor Pressure of a gasoline used for service accumulation

and aging must be characteristic of the engine fuel during the season in which the

service accumulation takes place in the outdoors, or must be characteristic of the

engine fuel appropriately suited to the ambient conditions of an indoor test cell in which

the entire service accumulation takes place.

(2) Alternative fuels.

(i) Liquefied petroleum gas meeting the ASTM D1835 (11/10/1997) or

NGPA HD

- 5 (1970) specifications must be used for service accumulation.

(ii) Natural gas representative of commercial natural gas that is available

locally to the manufacturer’s test site may be used in service accumulation. T he

manufacturer must provide the Executive Officer with detail of how the commercial

natural gas differs from the certification test fuel specifications.
