Federal Register / Vol. 73, No. 126 / Monday, June 30, 2008 / Rules and Regulations 37345 

specifications as each lab instrument it 

replaces. For field testing or for testing 

with PEMS in a laboratory or similar 

environment, under the provisions of 

§ 1065.905(b), the specifications in the 

following table apply instead of the 

specifications in Table 1 of § 1065.205. 

* * * * * 

(c) Field-testing ambient effects on 

PEMS. We recommend that you use 

PEMS that are only minimally affected 

by ambient conditions such as 

temperature, pressure, humidity, 

physical orientation, mechanical shock 

and vibration, electromagnetic 

radiation, and ambient hydrocarbons. 

Follow the PEMS manufacturer’s 

instructions for proper installation to 

isolate PEMS from ambient conditions 

that affect their performance. If a PEMS 

is inherently affected by ambient 

conditions that you cannot control, you 

may monitor those conditions and 

adjust the PEMS signals to compensate 

for the ambient effect. The standardsetting part may also specify the use of 

one or more field-testing adjustments or 

measurement allowances that you apply 

to results or standards to account for 

ambient effects on PEMS. 

(d) * * * 

(1) Recording ECM signals. If your 

ECM updates a broadcast signal more or 

less frequently than 1 Hz, process data 

as follows: 

(i) If your ECM updates a broadcast 

signal more frequently than 1 Hz, use 

PEMS to sample and record the signal’s 

value more frequently. Calculate and 

record the 1 Hz mean of the more 

frequently updated data. 

(ii) If your ECM updates a broadcast 

signal less frequently than 1 Hz, use 

PEMS to sample and record the signal’s 

value at the most frequent rate. Linearly 

interpolate between recorded values and 

record the interpolated values at 1 Hz. 

(iii) Optionally, you may use PEMS to 

electronically filter the ECM signals to 

meet the rise time and fall time 

specifications in Table 1 of this section. 

Record the filtered signal at 1 Hz. 

* * * * * 

(5) * * * 

(iii) * * * 

(B) Use a single BSFC value that 

approximates the BSFC value over a test 

interval (as defined in subpart K of this 

part). This value may be a nominal 

BSFC value for all engine operation 

determined over one or more laboratory 

duty cycles, or it may be any other BSFC 

that you determine. If you use a nominal 

BSFC, we recommend that you select a 

value based on the BSFC measured over 

laboratory duty cycles that best 

represent the range of engine operation 

that defines a test interval for fieldtesting. You may use the methods of this 

paragraph (d)(5)(iii)(B) only if it does 

not adversely affect your ability to 

demonstrate compliance with 

applicable standards. 

* * * * * 

■ 138. Section 1065.920 is amended by 

revising paragraphs (a), (b)(4)(iii), and 

(b)(7) introductory text to read as 

follows: 

§ 1065.920 PEMS calibrations and 

verifications. 

(a) Subsystem calibrations and 

verifications. Use all the applicable 

calibrations and verifications in subpart 

D of this part, including the linearity 

verifications in § 1065.307, to calibrate 

and verify PEMS. Note that a PEMS 

does not have to meet the systemresponse specifications of § 1065.308 if 

it meets the overall verification 

described in paragraph (b) of this 

section. This section does not apply to 

ECM signals. 

(b) * * * 

(4) * * * 

(iii) If the standard-setting part 

specifies the use of a measurement 

allowance for field testing, also apply 

the measurement allowance during 

calibration using good engineering 

judgment. If the measurement allowance 

is normally added to the standard, this 

means you must subtract the 

measurement allowance from the 

measured PEMS brake-specific emission 

result. 

* * * * * 

(7) The PEMS passes this verification 

if any one of the following are true for 

each constituent: 

* * * * * 

■ 139. Section 1065.925 is amended by 

revising paragraph (h) to read as 

follows: 

§ 1065.925 PEMS preparation for field 

testing. 

* * * * * 

(h) Verify the amount of 

contamination in the PEMS HC 

sampling system as follows: 

(1) Select the HC analyzers’ ranges for 

measuring the maximum concentration 

expected at the HC standard. 

(2) Zero the HC analyzers using a zero 

gas or ambient air introduced at the 

analyzer port. When zeroing the FIDs, 

use the FIDs’ burner air that would be 

used for in-use measurements (generally 

either ambient air or a portable source 

of burner air). 

(3) Span the HC analyzers using span 

gas introduced at the analyzer port. 

When spanning the FIDs, use the FIDs’ 

burner air that would be used in-use (for 

example, use ambient air or a portable 

source of burner air). 

(4) Overflow zero or ambient air at the 

HC probe or into a fitting between the 

HC probe and the transfer line. 

(5) Measure the HC concentration in 

the sampling system: 

(i) For continuous sampling, record 

the mean HC concentration as overflow 

zero air flows. 

(ii) For batch sampling, fill the sample 

medium and record its mean 

concentration. 

(6) Record this value as the initial HC 

concentration, xTHCinit, and use it to 

correct measured values as described in 

§ 1065.660. 

(7) If the initial HC concentration 

exceeds the greater of the following 

values, determine the source of the 

contamination and take corrective 

action, such as purging the system or 

replacing contaminated portions: 

(i) 2% of the flow-weighted mean 

concentration expected at the standard 

or measured during testing. 

(ii) 2 μmol/mol. 

(8) If corrective action does not 

resolve the deficiency, you may use a 

contaminated HC system if it does not 

prevent you from demonstrating 

compliance with the applicable 

emission standards. 

■ 140. Section 1065.935 is amended by 

revising paragraphs (e)(1) and (g)(5) to 

read as follows: 

§ 1065.935 Emission test sequence for 

field testing. 

* * * * * 

(e) * * * 

(1) Continue sampling as needed to 

get an appropriate amount of emission 

measurement, according to the standard 

setting part. If the standard-setting part 

does not describe when to stop 

sampling, develop a written protocol 

before you start testing to establish how 

you will stop sampling. You may not 

determine when to stop testing based on 

emission results. 

* * * * * 

(g) * * * 

(5) Invalidate any test intervals that 

do not meet the drift criterion in 

§ 1065.550. For NMHC, invalidate any 

test intervals if the difference between 

the uncorrected and the corrected brakespecific NMHC emission values are 

within ±10% of the uncorrected results 

or the applicable standard, whichever is 

greater. For test intervals that do meet 

the drift criterion, correct those test 

intervals for drift according to 

§ 1065.672 and use the drift corrected 

results in emissions calculations.

Subpart K—[Amended] 

■ 141. Section 1065.1001 is amended by 

revising the definitions for ‘‘Designated 

Compliance Officer’’, ‘‘Regression 

statistics’’ and ‘‘Tolerance’’ and adding 

definitions in alphabetical order for 

‘‘Dilution ratio’’, ‘‘Measurement 

allowance’’, ‘‘Mode’’, ‘‘NIST-accepted’’, 

‘‘Recommend’’, ‘‘Uncertainty’’, and 

‘‘Work’’ to read as follows: 

§ 1065.1001 Definitions. 

* * * * * 

Designated Compliance Officer means 

the Director, Compliance and Innovative 

Strategies Division (6405–J), U.S. 

Environmental Protection Agency, 1200 

Pennsylvania Ave., NW., Washington, 

DC 20460. 

* * * * * 

Dilution ratio (DR) means the amount 

of diluted exhaust per amount of 

undiluted exhaust. 

* * * * * 

Measurement allowance means a 

specified adjustment in the applicable 

emission standard or a measured 

emission value to reflect the relative 

quality of the measurement. See the 

standard-setting part to determine 

whether any measurement allowances 

apply for your testing. Measurement 

allowances generally apply only for 

field testing and are intended to account 

for reduced accuracy or precision that 

result from using field-grade 

measurement systems. 

Mode means one of the following: 

(1) A distinct combination of engine 

speed and load for steady-state testing. 

(2) A continuous combination of 

speeds and loads specifying a transition 

during a ramped-modal test. 

(3) A distinct operator demand 

setting, such as would occur when 

testing locomotives or constant-speed 

engines. 

NIST-accepted means relating to a 

value that has been assigned or named 

by NIST. 

* * * * * 

Recommend has the meaning given in 

§ 1065.201. 

Regression statistics means any of the 

regression statistics specified in 

§ 1065.602. 

* * * * * 

Tolerance means the interval in 

which at least 95% of a set of recorded 

values of a certain quantity must lie. 

Use the specified recording frequencies 

and time intervals to determine if a 

quantity is within the applicable 

tolerance. The concept of tolerance is 

intended to address random variability. 

You may not take advantage of the 

tolerance specification to incorporate a 

bias into a measurement. 

* * * * * 

Uncertainty means uncertainty with 

respect to NIST-traceability. See the 

definition of NIST-traceable in this 

section. 

* * * * * 

Work has the meaning given in 

§ 1065.110. 

* * * * * 

■ 142. Section 1065.1005 is amended by 

revising paragraphs (a) and (g) to read as
