### 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 compensatefor 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 operationthat 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 PEMSdoes 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, x THCinit 

### , 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 μ mol/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 betweenthe 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. * * * * *VerDate Aug<31>2005 18:15 Jun 27, 2008 Jkt 214001 PO 00000 Frm 00252 Fmt 4701 Sfmt 4700 E:\FR\FM\30JNR3.SGM 30JNR3mstockstill on PROD1PC66 with RULES3

### 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. * * * * * ■
