§ 2139. Testing. 

After the vehicles have been accepted and restorative maintenance, if 

any, has been performed, the ARB or its designated laboratory shall perform the applicable emission tests pursuant to the following: 

(a) For passenger cars and light duty trucks, in usc compliance emisston tests shall be performed pursuant to section 1960.1, 1961, 1961.2, 

or 1961.3, Title 13, California Code of Regulations, us applicable. 

(b) For medium duty vehicles certified according to the chassis standards and test procedures specified in section 1960.1, 1961, 1961.2, or 

1961.3, 

Trtlc 13, California Code ofRCJ.rulutions and the documents incorporaled by reference therein, in usc compliance emission tests shall 

be performed pursuant to section 1960.1, 1961, 1961 .2, or 1961.3, Title 

13, California Code of Regulations, as applicable. 

(c) For medium duty engines and vehicles certified according to the 

optional engine test procedures specified in section 1956.8, Title 13, California Code of Regulations and the documents incorporated by reference therein, in usc compliance emission tests shall be performed pursuant to one of the followmg procedures: 

(I ) The engines of medium duty vehicles may be tested pursuant to 

the engine test procedures specified in section 1956.8, provided that the 

manufacturer or its dcs:gnatcd laboratory conduct procurement and enforccmenttesting pursuantto Sections 2136through 2140, Title 13, Califomia Code of Regulation, at the manufacturer's expense. 

For manufacturers that have only one engine family or test group, the 

manufacturer or its designated laboratory that have more than one engine 

family or test group, the manufacturer or its designated laboratory shall 

procure no more than fifteen vehicles per engine family or test group. For 

manufacturers that have more than one engine family or test group, the 

manufacturer or il& designated laboratory shall procure and test at the 

p

prove the manulitcturcr's procurement procedures in advance of their usc 

by the manufacturer. The Executive Officer shall approve a manufacturer's procurement procedures if engines arc screened according to the criteria specified in section 2137, Title 13, California Code of Regulations 

and selected randomly from registration records compiled and prepared 

by R. L. Polk nnd Compnny or u compnrublc source. In addition, novehicle shnll be selected for enforcement testing with mileage less thnn 60 

percent of the useful life milcugc without prior approval from the Executive Officer. 111c manufacturer shall permit an ARB reprcscntotivc to 

witness procurement, restorative muintcnuncc, and cnforecmcnttesl in g. 

The Executive Officer shall have the authority to accept or reject a test 

engine based upon criteria specified in section 2137. Once an engine has 

been tested and determined to be in compliance with the current in usc 

emission standards, no further testing will be performed on subsequent 

engine families or test groups that corry over the durability datu of the 

tested engine family or lest group. 

Notwilhstonding the above, if a manufacturer fails to dcmonstralc 

compliance with the emission standards uftcronc third ofits engine families or test groups have been tested, additional engine families or test 

groups shall be tested, by the mnnufacturcr or its designated laboratory, 

at the manufacturer's expense, until compliance is demonstrated on one 

third of the engine families or test groups or all of a manufacturer's engine families or test groups have been tested. In addition, any engine fomily or test group which has been tcslcd and dclcrminc4 to be in 

noncompliance shall be retested by the manufacturer each subsequent 

year until compliance with the upplicoblc emission slandards has been 

demonstrated. Notwithstanding the above, the ARB may conduct engine 

enforcement testing pursuant to the engine test procedures specified in 

section 1956.8, at their own cxpen'lc. 

(2) Medium duty vehicl~o'S may be tested according to the chassis test 

procedures specified in section 1960.1 (k), 1961, or 1961.2, us applicublc, 

tf u manufacturer develops correlation facto~ which establish the relationship between engine and chassis testing for each engine family or test 

group and submits these correlation factors 

within one year after the beginning of production. The correlation factol"i shall be applied to lhe 

measured in usc engine exhaust emission data to determine Jhe in usc 

engine exhaust emission levels. All correlation factors and supporting 

datu included in u mnnufcJcturcr's application must be submitted to and 

approved by the [xccuttvc Officer in .tdvance ofthcir usc by a manufacturer. Correlation factors intended to apply to a ~opec fic engine family or 

test group shall be applicuble for each vehicle model incorporating that 

specific en •inc. Manufacturers shall submit test data demonstrating the 

applicability of the correlation factors for vehicle models comprising a 

minimum of80 percent of their engine sales for that specific engine family or test group. The correlation factors for the remaining fleet may be 

determined through an engineering evaluation bused upon a comp.:~ ,on 

with similar vehicle models. The Executive Officer shall apProve a submitted correlation factor if it aecuratcly corresponds to other established 

empirical and thcorcticul correlation factors and to emission test data 

available to the Executive Officer. 

A manufacturer may choose to usc the results from the chassis in usc 0 

testing as a screening test. If an engine family or test group docs not demonstrate compliance with any of the applicable in-usc engine standards, 

as determined from the chassis test data and the applied correlation facPage 140.2(J)(6) Raplu21112, Na.32;1-IG-2111!

lorccmcnt testing requirements and costs of in usc compliance engine 

testing, as specified in section 2139(c)(l). 

(3) The manufacturer shall choose one of the procedures specified in 

subsections (c)( I) through ( c X2). The Executive Officer shu II permit the 

usc of alternative test procedures if the Executive Orticer dctcnnincs the 

alternative test procedure adequately predicts the exhaust emissions 

from the engine test procedure specified in section I 956.8, Title I 3, California Code of Regulations. Such a dctcnninalion may be based upon 

correlation with test dutu from the engine test procedures. 

(4) The time limits specified in subsections (c)( I) and (c)(2) may be 

extended by the Executive Officer if the manufacturer dcmonstr.ttcs that 

the time limits specified could not be achieved due to reasons beyond the 

reasonable control of the manufacturer. 

(d) For heavy duty engines and vehicles, in usc compliance emission 

tests shall be pcrfonncd pursuant to section I 956.8, Title I 3, California 

Code of Regulations. 

(c) For motorcycles, in usc compliance emission tests shall be perfunned pursuant to section I 958, Title I 3, California Code of Regulations. 

(t) For off road motorcycles and all terrain vehicles, in usc compliance tests shall be pcrfonncd pursuant to section 2412, Title 13, California Code of Regulations. Titc in usc compliance testing shall usc the 

same test procedure utili7.cd for the specific original certification testing. 

(g) For off road compression ignition engines, in usc compliance 

tests shall be pcrfonncd pursuant to Section 2423, Title 13, California 

Code of Regulations. The in usc compliance testing shall usc the same 

test procedure utili7cd for the specific engine's original certification testing. 

(h) For spark ignition stcmdrivc/inboard murine engines, in UhC 

compliance tests shall be pcrfonned pursuant to section 2442, Title I 3, California Code of Regulations. The in usc compliance testing shall usc 

the some test procedure utili7cd for the specific engine's original certification testing. 

(i) For any emission in usc compliance test pcrfonncd pursuant to 

subsections (a) through (h), the ARB muy waive a specific test for subsequent vehicle samples from vehicle samples already tested arc 

deemed sufficient to establish complying emission levels. The ARB shall 

infonn the manufacturer at 30 days prior to enforcement testing of its vehicles or engines and shall penn it a manufacturer representative to 

observe the enforcement testing.
