Section 10.12.080 Standards and Specifications for Exhaust Gas Analyzers and Span Gases for Equipment Used to Perform Enhanced Basic Testing.


Prior to the adoption of Ord. 03-2002 on 10/01/2002, Section 10.12.080 read as follows.

    A.    DC98UTAH2000 exhaust gas analyzer.:  specifications for the DC98 UTAH2000 analyzer are contained in Section 10.12.240 of this Ordinance.
    1.    Emissions inspections required by this chapter Ordinance for vehicles subject to enhanced basic I/M inspections shall be performed using only instruments approved by the Division. the UTAH2000 analyzer.
    2.    Any analyzer used by an enhanced basic I/M program station shall be registered with and approved by the Division. and, if required, shall bear a registration sticker issued by the Division. Registration stickers are not transferable or assignable. Any new or used exhaust gas analyzer put in use after enhanced basic I/M program station approval must be approved by the Division before use. Analyzers used temporarily during times of breakdown or repair of the registered analyzer do not require a registration sticker but shall meet all other requirements of this Section including the approval of the Division before use.
    a.    The analyzer printers shall be maintained in such a manner that the printing of the certificate and inspection report shall be clearly visible on all copies. If any printer fails to properly function, then the enhanced basic I/M program station shall discontinue testing until the required repairs have been performed.
    3.    Propane Equivalency Factor (P.E.F.). Each instrument shall be labeled with a valid propane equivalency factor, shown with an accuracy of at least two decimal places, (i.e., 0.52). P.E.F. confirmation shall be made on each assembled analyzer by measuring both N-hexane and propane values on assembly line quality checks. If the analyzer bench is replaced, then a new P.E.F. label applicable to the replacement bench shall be appropriately attached to the analyzer.
    4.3.     Running changes.:  Any changes to the design characteristics or component specifications that may affect the performance of an exhaust gas analyzer to be used as an official test instrument in the Davis County I/M program shall be approved by the Division. It shall be the instrument manufacturer’ s responsibility to confirm that the changes have no detrimental effect on the performance of the exhaust gas analyzer.
    a.    It shall be illegal for any person to modify the hardware or software of an approved emissions analyzer without written application and formal written approval by the Division.
    5.    Required Upgrade of the UTAH91 Analyzer. Beginning January 1, 1998, All UTAH91 analyzers continuing to be used in the DC98 program and all analyzers brought into the program shall be upgraded with such hardware and software changes as specified by the Division as to make them capable of real time data transmission, nitrogen oxide emission control equipment function testing data management, upgraded bench and printing capability and other upgrades deemed necessary by the Division. Upgraded analyzers will then be called DC98 analyzers.
    6.4.     Calibration/span gases.
    a.    General.:   The instrument manufacturer and/or his designated marketing vendors shall, on request, supply at a reasonable cost, span gases approved by the Division to any ultimate purchaser of his unit. Each new or used instrument sold by the instrument manufacturer or marketing vendor shall have approved full span gas containers installed and operational at the time of delivery. The Division shall establish necessary procedures for approving span/calibration gases.
    b.    Span gas blends.:   The span gases supplied to any enhanced basic I/M program station shall conform to the BAR97 specifications of the Division. All span/calibration gases shall meet all Federal requirements for the emissions warranty coverage. Two span/calibration gases shall be used to perform analyzer calibration. Both a low range and a mid to high range gas approved by the Division shall be used. Only gas blends supplied by Division approved blenders shall be used to calibrate official I/M test analyzers.
    7.5.     Documentation, logistics, and warranty requirements.
    a.    An instruction manual shall accompany each exhaust gas analyzer and shall contain at least the following information for the analyzer:
    i.    A complete technical description;
    ii.    The functional mechanical and electrical schematics;
    iii.ii.    The accessories and options that are included and/or available;
    iv.iii.    The model number, identification marking and location;
    v.iv.    Operating maintenance including daily, weekly, and monthly, accommodations and procedures for maintaining sample system integrity including, but not limited to, leaks, hang-up, calibration and filters. The services to be performed only by the manufacturer shall be clearly identified;
    vi.    Field calibration procedures (i.e., Division inspection procedure with separate gas supply);
    vii.    Cal-port gas inlet calibration, zero, and span instructions;
    viii.v.    Information concerning the nearest service facility where equipment can be serviced; and
    ix.vi.    The warranty provisions for the analyzer, including a list of warranty repair facilities by name, address and telephone number.
    x.vii.    The analyzer shall be maintained in accordance with the manufacturer’s recommended maintenance schedule and records of this maintenance service shall be maintained for examination by the Division.
    B.    The Division shall use and require for use in the calibration of exhaust gas analyzers, calibration/span gases and containers meeting the guidelines contained in subsection (A)(6) of this section.
    C.B.    Gas span and leak check.
    1.    A certified emissions repair technician or certified emissions tester shall perform a gas calibration of the exhaust gas analyzer, with an approved calibration/span gas, within three (3) days prior to performing any emissions test, and a leak check within twenty-four (24) hours prior to performing any emissions test. The gas calibration and leak check must be performed in accordance with the analyzer specifications as referenced in Section 10.12.240. as prompted by the UTAH2000 analyzer.
    2.    All gas calibration and leak check records shall be retained and made available to the Division representatives for review and verification that the appropriate gas span and leak checks are being performed.
    3.2.     The analyzer instruction manual and other Division approved information shall be reviewed by the certified emissions repair technician or certified emissions tester to ensure that proper procedures are being used for performing the gas calibration check.
    D.    At any time where the analyzer requires repairs in order to be used in accordance with this chapter, the enhanced basic I/M program station shall notify the Division that the analyzer is “out-of-service” and shall again notify the Division after repairs are made and before testing is resumed.
    E.    An NCR type “carbonless” two-part eight-inch by eleven (11) inch form shall be used on the non-dedicated printer for printing the inspection report and other reports required by the Division unless otherwise determined by the Division. (Ord. 7-1996 § 1 (part))
