sport vehicles, off-road utility vehicles, and sand cars (Class I and Class II) may 

use the emission test procedures incorporated in California Code of Regulations, 

Title 13, Sections 2403 to certify their vehicles. Manufacturers of Class III allterrain vehicles must use the emission test procedures of Section 2403. The 

Executive Officer shall grant approval to those manufacturers who provide 

information and test results showing the appropriate emission standards on the 

small off-road engine test cycle that are equivalent to the all-terrain vehicle 

emission standards set forth in 86.410-90(a)(1). The Executive Officer shall 

consider data submitted by the manufacturer from engines similar to the engine 

to be certified. This data will include, but not be limited to, the engine size, 

performance, operating characteristics, and technology used. The data should 

be statistically valid in order to set the complying emissions standard applicable

* * * *

(c) DELETE,

REPLACE WITH:

(c) To compare emission levels with the emission standards, apply deterioration factors 

to the measured emission levels. For permeation emissions, use the following 

procedures to establish an additive deterioration factor. An additive deterioration factor 

for a pollutant is the difference between emissions at the end of the useful life and 

emissions at the low-hour test point. In these cases, adjust the official emission results 

for each tested vehicle or engine at the selected test point by adding the factor to the 

measured emissions. If the factor is less than zero, use zero. Additive deterioration 

factors must be specified to one more decimal place than the applicable standard:

(1) Section 1051.515 of these test procedures specifies how to test your fuel tanks to 
II-32

develop deterioration factors. Small-volume manufacturers may use assigned 

deterioration factors that we establish. Apply the deterioration factors as follows:

(i) Calculate the deterioration factor from emission tests performed before and after the 

durability tests as described in sections 1051.515(c) and (d) of these test procedures, 

using good engineering judgment. The durability tests described in section 1051.515(d) 

of these test procedures represent the minimum requirements for determining a 

deterioration factor. You may not use a deterioration factor that is less than the 

difference between evaporative emissions before and after the durability tests as 

described in sections 1051.515(c) and (d) of these test procedures.

(ii) Do not apply the deterioration factor to test results for tanks that have already 

undergone these durability tests.

(1) Fill the tank with the fuel specified in section 1051.501(d)(2)(i) of these test 

procedures, seal it, and allow it to soak at 28 ±5 °C for 20 weeks. Alternatively, the tank 

may be soaked for a shorter period of time at a higher temperature if you can show that 

the hydrocarbon permeation rate has stabilized.

(a)(3) DELETE.

REPLACE WITH:

(a)(3) Fill the fuel tank with the test fuel specified in section 1051.501(d)(2)(ii) of these 

test procedures to its nominal capacity. If you fill the tank inside the temperaturecontrolled room or enclosure, do not spill any fuel.

* * * *

(b)(7) DELETE.

REPLACE WITH:

(b)(7) At the end of the soak period, weigh the sealed fuel tank and record the weight to 

the nearest 0.1 grams. You may use less precise weights as long as the difference in 

mass from the start of the test to the end of the test has at least three significant figures. 
II-35

Unless the same fuel is used in the preconditioning fuel soak and the permeation test

run, record weight measurements on five separate days per week of testing. The test is 

void if a linear plot of tank weight vs. test days for the full soak period for permeation 

testing specified in paragraph (b)(5) of this section yields a coefficient of determination

difference between permeation emissions measured before and after the durability 

testing described in paragraph (d) of this section. Adjust the baseline test results for 

each tested fuel tank by adding the deterioration factor to the measured emissions. The 

deterioration factor determination must be based on good engineering judgment. 

Therefore, during the durability testing, the test tank may not exceed the fuel tank 

permeation standard described in section 2412(b), Title 13, CCR, (this is known as 

“line-crossing”). If the deterioration factor is less than zero, use zero.
