    comparison of the test standards contained in 35 Ill. Adm. Code 240.152 with the
    measured value for HC and CO as described in subsection (c) of this Section. A
    vehicle passes the test mode if any pair of simultaneous measured values for HC
    and CO are below or equal to the applicable test standards. A vehicle fails the
    test mode if the values for either HC or CO, or both, in all simultaneous pairs of
    values are above applicable standards.
    e)
    Test Sequence
    The steady-state idle test consists of a first-chance test and a second-chance test.

    The first-chance test consists only of an idle mode. The second-chance test
    consists of a preconditioning mode followed immediately by an idle mode, and is
    performed only if the vehicle fails the first-chance test.
    1)
    First-Chance Test
    A)

    a)
    Applicability
    The evaporative system integrity test shall be performed in accordance with the
    fuel cap leak flow test procedures or fuel cap pressure decay test procedures, and
    fuel cap visual functional test procedures specified in subsections (b) and (c) of
    this Section.
    b)
    Test Procedures
    1)
    Fuel Cap Leak Flow Test
    The fuel cap shall be removed from the vehicle's fuel inlet and installed on
    the fuel cap leak flow tester, using an adapter if necessary. All fuel caps
    that require a key for removal from the vehicle’s fuel inlet shall be tested
    with the key removed from the lock. At Official Inspection Stations, the
    lane computer shall provide the lane operator with information as to
    whether the fuel cap tester can be used to test the vehicle's fuel cap and
    which adapter, if any, is required, based on one or more of the following
    items: VIN, make, model, and model year. If the fuel cap can be tested,
    then the following task shall be performed:
    A)
    the fuel cap leak flow tester shall be pressurized to 30
    + 1 inches of
    water. The inspector shall initiate the test. The fuel cap leak flow

    tester shall measure the fuel cap leak flow rate and simultaneously
    compare this flow rate with the flow rate through the calibrated
    orifice;
    B)
    within 15 seconds after the depression of the start-test button, the
    fuel cap leak flow tester shall make a pass/fail determination.
    Pass/fail analysis shall be determined according to the procedures
    in subsection (c) of this Section;
    C)
    fuel caps which have failed an initial integrity test under
    subsection (c)(4) of this Section shall immediately receive a
    second-chance fuel cap leak flow test after first ensuring that the
    fuel cap has been installed on the fuel cap leak flow tester
    correctly. The procedure contained in subsections (b)(1)(A) and
    (b)(1)(B) of this Section shall be repeated; and
    D)
    at the conclusion of all fuel cap leak flow tests, the fuel cap shall
    be removed from the fuel cap leak flow tester and replaced on the

    2)
    Fuel Cap Pressure Decay Test
    The fuel cap shall be removed from the vehicle’s fuel inlet and installed
    on the fuel cap pressure decay tester, using an adapter if necessary. All
    fuel caps that require a key for removal from the vehicle’s fuel inlet shall
    be tested with the key removed from the lock. At Official Inspection
    Stations, the lane computer shall provide the lane operator with
    information as to whether the pressure decay tester can be used to test the
    vehicle’s fuel cap and which adapter, if any, is required, based on one or
    more of the following items: VIN, make, model, and model year. If the
    fuel cap can be tested, then the following task shall be performed:
    A)
    the pressure decay tester shall be pressurized to 28
    ±
    1 inches of
    water. The inspector shall initiate the test. The pressure decay
    tester shall monitor the pressure behind the fuel cap and look for
    pressure decay;
    B)
    the pressure decay shall be monitored for 10 seconds after stability
    is achieved for 10 seconds. Pass/fail analysis shall be determined
    according to the procedures in subsection(c)of this Section;
    C)
    fuel caps that have failed an initial integrity test under subsection
    (c)(4) of this Section shall immediately receive a second-chance
    fuel cap pressure decay test after first ensuring that the fuel cap has
    been installed on the pressure decay tester correctly. The
    procedure contained in subsections (b)(2)(A) and (b)(2)(B) of this

    Section shall be repeated; and
    D)
    at the conclusion of all fuel cap pressure decay tests, the fuel cap
    shall be removed form the pressure decay tester and replaced on
    the filler neck, ensuring that it is properly tightened.
    3)
    Visual Functional Test
    If the vehicle has a fuel cap, but the fuel cap cannot be tested using the
    leak flow or pressure decay test procedures, then a visual functional test of
    the fuel cap shall be performed.
    c)
    Pass/Fail Determination
    1)
    Vehicles which are presented for testing with missing, inaccessible,
    incorrect, non-removable, illegal, or otherwise non-testable fuel caps shall
    fail the evaporative system integrity test.
    2)
    If the vehicle’s fuel cap is present and can be tested using either the fuel
    cap leak flow test or the fuel cap pressure decay test under subsection
    (b)(1) or (b)(2) of this Section and, if tested, the test result does not exceed
    either the fuel cap leak flow rate standard contained in 35 Ill. Adm. Code
    240.172(b) or the fuel cap pressure decay standard contained in 35 Ill.
    Adm. Code 240.172(a), then the vehicle shall pass the evaporative system
    integrity test.
    3)
    If the vehicle’s fuel cap is present and is tested under the provisions of
    subsection (b)(3) of this Section, and the test result does not exceed the
    visual functional test standard contained in 35 Ill. Adm. Code 240.172(c),
    then the vehicle shall pass the evaporative system integrity test.
    4)
    If the vehicle’s fuel cap is tested using either the fuel cap leak flow test or
    the fuel cap pressure decay test under the provisions of subsection (b)(1)
    or (b)(2) of this Section and does not meet the applicable standards
    contained in 35 Ill. Adm. Code 240.172, the vehicle shall fail the
    evaporative system integrity test.
    (AGENCY NOTE: No vehicle will be failed under subsection (c) until applicable
    standards have been adopted at 35 Ill. Adm. Code 240 and are effective.)

    163.6
    167.0
    180.0
    234.5
    Gear shifts shall occur at the points in the driving cycle where the
    specified speeds are obtained. For vehicles with fewer than 6 forward
    gears the same schedule shall be followed with shifts above the highest
    gear disregarded.
    4)
    Speed excursion limits shall apply as follows:
    A)
    The upper limit is 2 mph higher than the highest point on the trace
    within 1 second of the given time.
    B)
    The lower limit is 2 mph lower than the lowest point on the trace
    within 1 second of the given time.

    C)
    Speed variations greater than the tolerances (such as may occur
    during gear changes) are acceptable provided that they occur for
    no more than 2 seconds on any occasion.
    D)
    Speeds lower than those prescribed during accelerations are
    acceptable provided the vehicle is operating at maximum available
    power during such accelerations until the vehicle speed is within
    the excursion limits.
    E)
    Exceedences of the limits in subsections (e)(4)(A) through
    (e)(4)(C) of this Section shall automatically result in a void test.
    Station supervisory personnel can override the automatic void of a
    test if it is determined that the conditions specified in subsection
    (e)(4)(D) of this Section occurred. These conditions shall be
    verified by repeating seconds 0 through 16 of the transient driving
    cycle as specified in subsection (e) of this Section.
    F)
    The test shall be aborted and immediately restarted if speed
    excursion limits are exceeded, except as described in subsection
    (e)(4)(D) of this Section.
    5)
    Speed Variation Limits
    The speed variation limits shall be determined by one of the following
    methods:
    A)
    Linear Regression Method
    i)
    A linear regression of feedback value on reference value
    shall be performed on each transient driving cycle for each
    speed using the method of least squares, with the best fit
    equation having the form: y = mx + b, where:
    y = The feedback (actual) value of speed
    m = The slope of the regression line
    x = The reference value
    b = The y-intercept of the regression line
    ii)
    The SE of y on x shall be calculated for each regression
    line. A transient driving cycle lasting the full 240 seconds
    that exceeds the following criteria shall be void and the test
    shall be repeated:
    SE = 2.0 mph maximum
    m = 0.96 - 1.01
    r(2) = 0.97 minimum
    b = 2.0 mph

    iii)
    A transient driving cycle that ends before the full 240
    seconds that exceeds the following criteria shall be void
    and the test shall be repeated:
    SE = (Reserved)
    m = (Reserved)
    r(2) = (Reserved)
    b = (Reserved)
    B)
    Positive Kinetic Energy (PKE) Method
    i)
    The speed variation limits shall be determined by the
    following equation for Positive Kinetic Energy (PKE):
    N
    x
    E = SUM PP[t] / INT x dx
    t=0
    0
    where:
    PP[t] = V(2)[t] – V(2)[(t-1)] mi(2)/hr(2) for
    V[t] > V[(t-1)]
    PP[t] = 0 for V[t] <= 0
    x = distance (miles)
    PP[t] = Positive Specific Power at time t
    V[t] = Velocity at time t
    V[(t-1)] = Velocity at time t-1
    ii)
    A transient driving cycle lasting the full 240 seconds with a
    PKE value that is below the lower PKE limit for passing
    vehicles or above the upper limit for failing vehicles shall
    be void and the test shall be repeated:
    Upper Limit: PKE > 3456 mi/hr(2)
    Lower Limit: PKE < 3082 mi/hr(2)
    iii)
    A transient driving cycle that ends before the full 240
    seconds with a PKE value that is below the lower second-
    by-second PKE limit for passing vehicles or above the
    upper second-by-second PKE limit for failing vehicles shall
    be void and the test shall be repeated. The second-by-
    second upper and lower PKE limits are specified in Section
    276.Table B.
    iv)
    PKE values shall not be used to make early pass/fail
    determination.
    6)
    The actual distance traveled for the transient driving cycle shall be
    measured. If the absolute difference between the measured

    distance and the theoretical distance for the actual test exceeds
    0.05 miles, the test shall be void.
    7)
    The vehicle shall be rejected if, during the course of the transient
    loaded mode test, station supervisory personnel verify that the test
    cannot be completed due to the mechanical condition of the
    vehicle.
    8)
    Inertia Weight Selection
    Operation of the inertia weight selected for the vehicle shall be
    verified as specified in Section 276.506(a) of this Part. For
    systems employing electrical inertia simulation, an algorithm
    identifying the actual inertia force applied during the transient
    driving cycle shall be used to determined proper inertia simulation.
    9)
    The CVS operation shall be verified for each test for a CFV-type
    CVS by measuring either the absolute pressure difference across
    the venturi or measuring the blower vacuum behind the venturi for
    minimum levels needed to maintain choke flow for the venturi
    design. The operation of a SSV-type CVS shall be verified
    throughout the test by monitoring the difference in pressure
    between upstream and throat pressure. The minimum values shall
    be determined from system calibrations. Monitored pressure
    differences below the minimum values shall void the test.
    10)
    Fuel Economy
    For each test, the quality of the overall analysis system shall be
    evaluated by checking a test vehicle's fuel economy for
    reasonableness, relative to upper and lower limits, representing the
    range of fuel economy values normally encountered for the test
    inertia and horsepower selected. For each inertia selection, the
    upper fuel economy limit shall be determined using the lowest
    horsepower setting typically selected for the inertia weight, along
    with statistical data, test experience, and engineering judgment. A
    similar process for the lower fuel economy limit shall be used with
    the highest horsepower setting typically selected for the inertia
    weight. For test inertia selections where the range of horsepower
    settings is greater than 5 horsepower, at least two sets of upper and
    lower fuel economy limits shall be determined and appropriately
    used for the selected test inertia. Tests with fuel economy results
    in excess of 1.5 times the upper limit shall result in a void test.
    11)
    System Lockout

    If a void occurs as described in subsections (e)(6), (e)(9), or
    (e)(10) of this Section, then a test lane system lockout shall be
    initiated. No further testing shall be done until the problem is
    corrected by station supervisory personnel. At Official Inspection
    Stations, the vehicle involved shall be immediately retested in a
    properly operating lane.
    f)
    Transient Loaded Mode Exhaust Gas Test Score Calculations
    The transient loaded mode exhaust gas test score shall be determined according to
    the method specified in 40 CFR 85.2205(b) (Draft), incorporated by reference in
    Section 276.104(a) of this Part, with the following exceptions:
    1)
    The Phase 2 scores for the test shall be determined by dividing the sum of
    the mass of each pollutant obtained in each second of the Phase 2 test by
    the number of miles driven in the Phase 2 test. The first data point is the
    sample taken from t=94 to t=95. The Phase 2 test score shall be
    determined by the following equation:
    s
    SUM grams of emissions
    Phase 2 gpm = t=94
    s
    SUM miles traveled
    t=94
    Where s = duration of test in seconds for fast
    pass, or s = 239 seconds for complete transient loaded mode exhaust gas
    test.
    2)
    NO
    xe
    = Nitrogen oxide concentration of the dilute exhaust sample as
    measured in ppm and multiplied by 1.03.
    3)
    NO
    xd
    = Background nitrogen oxide concentration of the dilution air,
    sampled as described in 40 CFR 85.2221(b)(5) (Draft), incorporated by
    reference in Section 276.104(a) of this Part, as measured in ppm and
    multiplied by 1.03.
    g)
    Pass/Fail Determination
    Compliance with the transient loaded mode exhaust emission test shall be made in
    accordance with the standards contained in 35 Ill. Adm. Code 240, Subpart E.

    All operators of exhaust gas analyzers shall conduct a preventive maintenance and quality
    control program consisting of the following elements:
    a)
    an HC hang-up check conducted prior to each test and after the last test of the
    day; HC hang-up shall not exceed 20 ppm HC prior to any test;
    b)
    visual inspection of all equipment prior to the first test of the day;
    c)
    performance of analyzer preventative maintenance, (e.g., filter replacement,
    inspection and cleaning of probes, sample lines, water traps, etc.) according to
    manufacturer's recommended schedules and as needed; and
    d)
    all calibration and operating procedures specified in Section 276.602.

    (Source: Amended at 22 Ill. Reg. 18867, effective September 28, 1998)
    Section 276.602
    Steady-State Idle Test Equipment Calibration
    All operators of steady-state idle test exhaust gas analyzers shall comply with the following
    calibration and operating procedures unless alternative procedures have been approved by the
    Agency:
    a)
    exhaust gas analyzers shall be warmed up prior to each vehicle inspection, zero
    check, span check, or calibration. Analyzers shall be considered to be in a
    warmed-up condition once stabilized zero readings (readings stabilize for one
    minute within ±2% of full scale, low range on all three channels) are obtained.
    b)
    The analyzer shall conduct an zero and span check prior to each test. The span
    check shall include the HC, CO and CO[2] channels, and the NO and O[2]
    channels, if present. If zero and/or span drift cause the signal levels to move
    beyond the adjustment range of the analyzer, it shall lock out from testing.
    c)
    The system shall lock out from testing if sample flow falls below three percent of
    full scale, or causes system response time to exceed 13 seconds to 90 percent of a
    step change in input, whichever is less.
    d)
    A system leak check shall be performed within four hours before the test, and
    may be performed in conjunction with the gas calibration described in subsection
    (e)(1) of this Section. If a leak check is not performed within four hours or if the
    analyzer fails the leak check, the analyzer shall lock out from testing. The leak
    check shall be a procedure demonstrated to effectively check the sample hose and
    probe for leaks and shall be performed in accordance with good engineering
    practices. An error of more than ±2% of the reading using low range span gas
    shall cause the analyzer to lock out from testing and shall require repair of leaks.
    e)
    Gas Calibration
    1)
    On each operating day, analyzers shall successfully pass a two-point gas
    calibration for HC, CO, and CO[2] and shall continually compensate for
    changes in barometric pressure. Calibration shall be checked within 4
    hours before the test and the analyzer adjusted if the reading is more than
    2% different from the span gas value. Gas calibration shall be
    accomplished by introducing span gas that meets the requirements of
    subsection (e)(3) of this Section into the analyzer through the calibration
    port. If the analyzer reads the span gas within the allowable tolerance
    range (i.e., the square root sum of the squares of the span gas tolerance
    described in subsection (e)(3) of this Section and the calibration tolerance,
    which shall be equal to 2%), no adjustment of the analyzer is necessary.
    The gas calibration procedure shall correct readings that exceed the
    allowable tolerance range to the center of the allowable tolerance range.

    The pressure in the sample cell shall be the same with the calibration gas
    flowing during calibration as with the sample gas flowing during
    sampling. If the system is not calibrated, or the system fails the
    calibration check, the analyzer shall lock out from testing.
    2)
    A two point gas calibration procedure shall be followed. The span shall be
    accomplished at one of the following pairs of span points:
    A)
    Low
    300--ppm propane (HC)
    1.0--percent CO
    6.0--percent CO[2]
    1000--ppm nitric oxide (if equipped with NO)
    High
    1200--ppm propane (HC)
    4.0--percent CO
    12.0--percent CO[2]
    3000-ppm nitric oxide (if equipped with NO)
    B)
    Low
    0-ppm propane (HC)
    0.0--percent CO
    0.0--percent CO[2]
    0--ppm nitric oxide (if equipped with NO)
    High
    600--ppm propane (HC)
    1.6--percent CO
    11.0--percent CO[2]
    1200--ppm nitric oxide (if equipped with NO)
    1)
    The span gases used for the gas calibration shall be traceable to NIST
    standards within two percent and shall be within two percent of the span
    points specified in subsection (e)(2) of this Section.
    f)
    Other Checks
    In addition to the other periodic checks described in this Section, those described
    in subsections (f)(1) and (f)(2) of this Section shall also be used to verify system
    performance under the special circumstances described therein.
    1)
    Gas Calibration
    A)
    Each time the analyzer electronic or optical systems are repaired or
    replaced, a gas calibration shall be performed prior to returning the
    unit to service.

    B)
    Monthly multi-point calibrations shall be performed. The
    calibration curve is checked at 20 percent, 40 percent, 60 percent,
    and 80 percent of full scale, and must be adjusted or repaired if the
    specifications in Section 276.503 are not met
    .
    2)
    Leak Checks
    Each time the sample line integrity is broken, a leak check shall be
    performed prior to testing.

    1)
    Pressure Decay Tester
    A)
    The fuel cap pressure decay tester shall be checked for integrity at
    the beginning of each operating day and after 5 hours of use each
    day. If, after the fuel cap attachment end of the pressure decay
    tester is capped and pressurized to between 14 and 28 inches of
    water, the pressure system changes more than 0.2 inches of water
    over 15 seconds, the pressure decay tester shall be removed from
    service.
    B)
    The pressure gauge for the pressure decay tester shall be checked
    on a weekly basis against a reference gauge. A pressure decay
    tester that has a deviation in the measured pressure exceeding 0.3
    inches of water shall be removed from service.
    2)
    Leak Flow Tester
    A)
    The accuracy of the leak flow tester shall be verified by testing and
    correctly identifying the passing and failing reference fuel caps at
    the beginning of each operating day. Reference fuel caps shall be
    stored in a dirt and dust free manner to prevent clogging and
    changes in flow rate. Reference fuel caps shall be stored at the
    same temperature as the leak flow fuel cap tester to provide
    accurate flow reference.
    B)
    Independent flow bench verification of the reference fuel caps and
    the internal flow standard orifice shall be conducted before initial
    usage and as recommended by the leak flow tester manufacturer or

    as suggested by analysis of quality control data. The bench flow
    verification results shall be traceable to NIST.
    C)
    The upstream filter for the leak flow tester shall be maintained in
    accordance with manufacturer’s specifications.
    b)
    Any fuel cap leak flow tester or pressure decay tester which fails an inspection
    shall be removed from service until repaired and its accuracy verified.
    c)
    The fuel cap adapters shall be checked for leaks or damage following the
    recommendations of the fuel cap tester manufacturer or the fuel cap adapter
    supplier.
