Diane Lee, NIST/OWM, reported that both items were approved by the
Conference and will appear in the 2008 issue of Handbook 44,
*Specifications, Tolerances and Other Technical Requirements for
Measuring Devices.*

Steve Patoray, NTEP Director, reported that the NCWM Board of Directors
adopted a more detailed policy on the use of the NTEP logo which is a
registered trademark of NCWM. All users of the NTEP logo will now be
required to sign a license agreement regarding its use. Additional
information regarding changes to the NCWM Publication 14 Administrative
Policy, the License Agreement, and guidelines on the use of the NTEP
logo will be placed on the NCWM website.

Steve Patoray noted that conformity assessment does not affect Grain
Analyzers at present. Conformity assessment remains an issue mostly of
interest to the Weighing Sector.

# Report on NTEP Type Evaluations and OCP (Phase II) Testing

Cathy Brenner of the Grain Inspection, Packers, and Stockyards
Administration (GIPSA), the NTEP Participating Laboratory for Grain
Analyzers, briefed the Sector on NTEP Type Evaluation activity. In
addition to regular grain moisture meter (GMM) calibration updates,
evaluation of the Perten AM5100 GMM was completed and a certificate of
conformance (CC) was issued in December 2006. She reported that the
following device types are enrolled in the OCP (Phase II) for the 2007
harvest:

\[Note: Models listed on a single line are considered to be of the same
"type."\]

DICKEY-john Corporation GAC2000, GAC2100, GAC2100a, GAC2100b

DICKEY-john Corporation OmegAnalyzer G

Foss North America Infratec 1241

Foss North America Infratec 1227, Infratec 1229

Perten Instruments AM5100

The Steinlite Corporation SL95

Ms. Brenner explained that although the CC for Seedburo Equipment
Company's 1299A does not expire until July 1, 2008, Seedburo has elected
not to enroll in Phase II for the 2007 harvest. Because there are still
six devices in the program, the same as in 2006, the cost to
manufacturers for Phase II will remain \$7,730 per meter type.

# Review of Ongoing Calibration Program (Phase II) Performance Data

At their August 2005 meeting, the Sector agreed that comparative OCP
data identifying the Official Meter and listing the average bias for
each NTEP meter type should be available for annual review by the
Sector. Accordingly, Cathy Brenner, representing GIPSA, the NTEP
Participating Laboratory for Grain Analyzers, presented data showing the
performance of NTEP meters compared to the air oven. These data are
based on the last three crop years (2004 ‑ 2006) using calibrations
updated for use during the 2007 harvest season.

Ms. Brenner pointed out that data on the DICKEY-john OmegAnalyzer G was
not included in the comparisons because it had only been in the program
for one year. Next year data on Perten's AM5100 will not be included for
the same reason. Comparisons of GMMs with less than three years of data
against GMMs with the full three years of data are not meaningful as
they may be unduly influenced by a single unusual crop year.

She noted that no Durum samples in the 16 % to 18 % Moisture Range had
been received since the 2002 harvest season. Dr. Richard Pierce, GIPSA,
observed that Medium Grain Rough Rice data showed very few samples in
the 14 % to 16 % Moisture Range while the adjacent ranges, both above
and below, show nearly four to five times that number. No one was able
to offer an explanation.

Cassie Eigenmann, DICKEY-john, offered the general comment that
performance data appears to be getting much better; meters are closer to
each other and closer to the air oven.

# Proposed Change to the GMM Chapter of Publication 14 to Avoid Reducing a Previously Evaluated Approved/Pending Moisture Range Due to Lack of Data

[]{#Agenda_Item4 .anchor}

**Background:** This is a carryover item from the Sector's August 2006
meeting. This issue was first raised at the Sector\'s 2005 meeting when
Dr. Richard Pierce, GIPSA (the NTEP Laboratory) mentioned that the NTEP
Laboratory was having problems increasing and decreasing "Approved" or
"Pending" ranges of grain moisture meters depending on the data
available in the most recent 3‑year period. Most Sector members agreed
that it didn\'t seem logical to reduce a range solely because data
previously used to justify the range classification had to be dropped
from the most recent 3‑year period.

At their 2006 meeting, the Sector discussed guidelines for possible
revisions to the GMM chapter of Publication 14 to address this problem.
Two of the most significant guidelines considered for revision were:

1.  Redefine "Pending" to be simply: "A new calibration that has not
    been validated by ongoing calibration data collected as part of the
    national calibration program."

2.  The maximum upper moisture interval and the minimum lower moisture
    interval that can be given "Approved" status will be defined for
    each grain. These upper and lower limits are to be fixed values that
    do not change from year to year.

Most Sector members were generally in favor of either redefining or
eliminating the "Pending" classification; however, this approach implied
that another method had to be found to determine operating ranges,
because "Pending" Moisture Ranges have traditionally been used to set
the upper and lower moisture limits (operating range) for each
calibration. Manufacturers objected to using a single fixed range for
all types of devices, noting that some technologies were more accurate
than others at high moistures. They preferred an option that would allow
them to competitively extend the operating range and objected to being
restricted by limitations in the Phase II sample collection system.
Subsequent discussion led to the suggestion that the manufacturer should
specify the operating Moisture Range for each grain. This range would
NOT be listed on the Certificate of Conformance (CC), but would be used
to determine when warnings would be displayed and printed to indicate
that the displayed/printed moisture content of a sample being measured
was beyond the operating range of the device. (See NIST Handbook 44,
Section 5.56.(a)., paragraphs S.1.1.(f) and S.1.3.(c).)

The Sector decided that additional study was needed before a final
recommendation could be made on this issue. The following points
summarize the Sector\'s thinking at the close of their August 2006
meeting:

1.  The "Pending Approval" classification will be eliminated. Operating
    ranges (upper and lower moisture limits) will be specified by the
    manufacturer. Operating ranges will NOT be listed on CCs.

2.  The three most recent years of Phase II data will continue to be
    used to evaluate calibration performance.

3.  Certificates will list a single "standard" Moisture Range for each
    grain calibration. These ranges will not vary from year-to-year.
    They will be the same for all instruments (see exception for new
    instruments). The "standard" ranges have to be wide enough to
    encompass the Moisture Ranges most commonly used in the market (to
    be determined) but narrow enough to assure that sufficient Phase II
    data will be available (over a three-year period) to:

    a.  permit a new meter\'s calibrations to be "verified" over those
        ranges by the end of its third year in Phase II; and

    b.  permit existing NTEP certified meters\' calibrations to be
        "verified" over those ranges using the most recent 3 years of
        Phase II data when the new rules are first adopted.

4.  Once a calibration has been "verified" a recalibration will not be
    forced due to lack of samples.

5.  New instruments will be "evaluated" over the basic 6 % Moisture
    Ranges for corn, soybeans, and hard red winter wheat. Certificates
    for new instruments will continue to list the 6 % Moisture Ranges as
    the "evaluated" or "verified" ranges until sufficient Phase II data
    has been collected to allow the new instrument to achieve "verified"
    status for the full Moisture Range.

6.  Outside the basic 6 % Moisture Range, tolerances that used to
    require a change in calibrations will continue to include the
    application of a 95 % confidence interval to the maximum tolerance
    for each 2 % moisture interval.

\[For additional background, see the Grain Analyzer Sector's August
23 ‑ 24, 2006, Meeting Summary, Agenda Item 7.\]

**Discussion:** To determine suitable "standard" Moisture Ranges, the
NTEP laboratory reviewed historical OCP data for the crop years 2000
through 2006, noting the total number of samples in each 2 % moisture
interval and each running 3‑year period. Additionally, for each 2 %
interval, they compared the basic approval tolerance (one-half the HB 44
acceptance tolerance) to the 95 % confidence interval tolerance that is
based on the number of samples. For an example of the data reviewed, see
Table 4.1 and Figure 4.1.

**Recommendation (1):** Based on the review of historical data, the NTEP
laboratory proposed grain specific recommendations for the following
Moisture Ranges and limits:

-   **Basic 6 % Interval** -- the Moisture Range used for Phase I Type
    Evaluation.

-   **Standard Moisture Range** -- the Moisture Range used for OCP
    Phase II calibration review.

-   **Maximum Moisture Limit** -- the upper moisture limit for
    calculating overall moisture bias in Phase II calibration review.

Grain-specific "standard" Moisture Ranges were selected to encompass the
2 % intervals where the majority of samples have been available and
where the basic approval tolerance (one-half the HB 44 acceptance
tolerance) was not significantly different from the tolerance that
includes the application of a 95 % confidence interval.

These ranges and the percent of samples represented in each proposed
Standard Moisture Range are listed in Table 4.2 along with the
corresponding GIPSA sample collection Moisture Range.

While reviewing the historical data, a trend was noticed in the data for
Oats. The bulk of the Oats data is from the 8 % to 14 % moisture
interval instead of the 10 % to 16 % moisture interval presently
specified in Publication 14. The NTEP lab proposes that the basic 6 %
Interval for Oats be changed to 8 % to 14 % moisture for both moisture
and test weight per bushel evaluation.

**Conclusion (1):** The Sector accepted Recommendation (1) by consensus
after the proposed Standard Moisture Ranges for both Medium Grain Rough
Rice and "All Class" Rough Rice were changed from 10 % to 24 % to
10 % to 20 % to agree with the Standard Moisture Range for Long Grain
Rough Rice. \[Note: Table 4.2, above, incorporates these changes.\]

**Recommendation (2): Ongoing Calibration Program (OCP) Calibration
Review**

The NTEP Laboratory proposed the following guidelines for OCP
calibration review:

1.  The most recent 3 years of data will still be used to determine if
    the calibration performance is acceptable.

2.  For each of their device types, manufacturers will be provided with
    a report listing all available data in 2 % moisture intervals. The
    report will indicate whether the calibration meets or exceeds the
    appropriate NTEP tolerances for each 2 % interval within the
    standard range and whether it meets or exceeds the overall moisture
    bias of ± .20 % moisture for all available data up to the Maximum
    Moisture Limit. (*Note: The current report indicates whether a
    calibration is "Approved," "Pending," or does not meet either
    tolerance for all available 2 % moisture intervals. The overall
    moisture bias in the current report is calculated using all
    available data.*)

3.  The status of "Approved," "Pending," and "Not Available" would be
    removed from both the Certificate of Conformance (CC) and
    Publication 14. Instead, only grain moisture calibrations that have
    passed Phase I or meet the tolerances for Phase II data will be
    listed on the CC. All other NTEP grains will be listed on the CC as
    "calibration not available."

4.  Manufacturer(s) will still be provided with all valid data collected
    during the OCP, even for samples exceeding the maximum limits.

**Conclusion (2):** Recommendation (2) was accepted by consensus.

**Recommendation (3): Certificate of Conformance**

The NTEP Laboratory has proposed the following guidelines for preparing
the Certificate of Conformance (CC):

The body of the CC will still report the moisture intervals used during
the Phase I evaluation. It will no longer list either the "Approved
Moisture Range" or the "Pending" Moisture Range. A grain will be listed
only if it meets either of the criteria listed below:

Phase I -- Passes either the Accuracy Test (corn, soybeans, hard red
winter wheat) or the Moisture Bias Check (the "Other 12" NTEP grains) as
currently specified in Publication 14.

Phase II -- Meets both the NTEP Phase II tolerances applied to each 2 %
moisture interval within the Standard Moisture Range and the NTEP
Phase II tolerance for overall moisture bias for all available data up
to the maximum moisture limits.

A comparison of the way a grain calibration appears on the current CC
with the way it will appear on the proposed CC is shown in Table 4.5.

+-----------------------------------+-----------------------------------+

**Discussion (3):** Most of the discussion on the NTEP Lab's
recommendations centered on the following questions:

1.  Should the manufacturer be required to submit data to support the
    operating ranges (upper and lower moisture limits) claimed by the
    manufacturer?

2.  Should the operating ranges (upper and lower moisture limits)
    claimed by the manufacturer be listed on the CC?

3.  How should the "standard" Moisture Ranges be specified on the CC?

4.  If a meter fails a single 2 % moisture interval outside the "basic"
    interval does the entire calibration fail or does the approval fall
    back to the "basic" interval?

Regarding question (1), some Sector members strongly favored requiring
the manufacturer to submit some kind of data supporting the claimed
upper and lower moisture limits for each grain, suggesting that big
problems could result if data were not required to be submitted. There
was concern that a manufacturer might use tempered grain to support an
operating range. Others were opposed to requiring manufacturer data
believing that it served no real purpose in that the Standard Moisture
Ranges encompass the moistures over which the vast majority of grain is
traded commercially. Furthermore, there would be no way that
manufacturer data could be verified in the field (or in the lab without
expensive testing) and that mandating its submission (and implied review
by the NTEP lab) would require more NTEP lab effort than it was worth.
Also, if the manufacturer decided to change a limit, modification of the
CC would be required even if no changes had been made in the
calibration. (Note: Manufacturers will still be required to submit data
with their initial application for Type Evaluation.)

As for question (2), the suggestion that CCs carry the notation,
"Evaluated over the Moisture Range of \_\_\_ % to \_\_\_ %, and
certified for use over the range of \_\_\_ % to \_\_\_ %," was
previously rejected by the Sector on the grounds that an NTEP
certificate was not intended to be a marketing tool. It was pointed out
that the functionality of displaying or printing a suitable warning
message whenever a moisture limit is exceeded is verified by the NTEP
lab in Phase I testing. Also, in practice when an elevator receives
grain at harvest with an indicated "exceeds upper moisture limit"
warning it typically ignores the warning message and receives the grain,
accepting the indicated moisture value.

Regarding question (3), there was general agreement that the verified
Moisture Ranges, whether "basic" or "standard" should be specified
explicitly somewhere on the CC. The NTEP laboratory representative
indicated that they were not overly opposed to including Standard
Moisture Ranges in the body of the CC. However, they were opposed to
including [any]{.underline} Moisture Ranges on the calibrations page.
The central argument was that the "basic" range would apply uniformly in
year 1 and the "standard" range thereafter, and that the table of these
ranges would be identical for all manufacturer certificates and would
not need to be changed or updated other than including a statement
indicating which verified range applies, i.e., "basic" or "standard."

Question (4) was answered quite simply. The entire calibration fails.
The manufacturer is obliged to revise the calibration and re-predict
moistures using the most recent three years of available Phase II raw
data. Concern that calibrations might be failed unjustly or might not be
able to be revised to "fit" available data were addressed by pointing
out that Publication 14 changes would be proposed to disregard any 2 %
interval containing less than five samples. Additionally, outside the
"basic" Moisture Range a 95 % confidence interval will be added to the
maximum tolerance.

**Conclusion (3):** With the understanding that manufacturer-supplied
calibration operating ranges would not be specified in the certificate,
but that verified ranges would be included in the body of the
certificate rather than in the calibration table, the Sector agreed to
Recommendation (3) by consensus.

**Final Conclusion/Recommendation:** Having agreed to accept the
recommendations/guidelines of the NTEP Laboratory, subject to the
changes noted in the above three conclusions, the Sector agreed by a
vote of 11 to 1 to accept the amendments/changes to Part IV of the Grain
Moisture Meter Chapter of *NCWM Publication 14* as originally proposed.
The deletion from Part V of "Special Cases Dealing with Inadequately
Represented Moisture Intervals" (except for a portion of "Special
Considerations for Multi-Class Calibrations"), was accepted by
consensus. Details of the recommended amendments/changes, designed to
avoid reducing a previously evaluated Approved/Pending Moisture Range
due to lack of data in the On-going Calibration Program (Phase II), and
the related changes to the 6 % moisture interval for Oats in Part VII
and Appendix D are shown below.

IV\. Tolerances for Calibration Performance

Calibration performance must be tested against established criteria at
the following stages of the type evaluation process:

> 1\. Evaluation of the calibration data supplied by the manufacturer
> with the application for type evaluation.
>
> 2\. Evaluating instrument and calibration performance over the 6 %
> Moisture Range for corn, HRW wheat and soybeans (accuracy test
> discussed earlier).
>
> 3\. Initial calibration approval for grains other than corn, HRW
> wheat, and soybeans.
>
> 4\. Review of ongoing calibration data collected as part of the
> national calibration program (Phase II).

Calibrations for corn, HRW wheat and soybeans will be approved initially
based upon type evaluation testing over a 6 % Moisture Range. The bias
of all samples in a 2 % moisture interval may not exceed one-half of the
Handbook 44 acceptance tolerance.

Calibrations for other grains will be approved initially based upon a
bias check using a set of 10 to 12 samples referenced to the FGIS air
oven laboratory and the FGIS official meter. "Multi-class" calibrations
will be bias checked using 10 to 12 samples of each individual grain
class included in the calibration. The maximum allowable overall bias
between the meter under test and air oven is ± 0.4 for this bias check.
An overall bias will be applied to the calibration in making approval
decisions.

In order for a calibration to remain on the certificate of conformance,
the calibration must continue to meet tolerances for all 2 % moisture
intervals in the Standard Moisture Range. This requirement is waived if
a 2 % moisture interval contains fewer than five samples. For 2 %
moisture intervals outside the basic 6 % Moisture Range, tolerances used
to require a change in calibrations will include the application of a
95 % confidence interval to the maximum tolerance for each 2 % moisture
interval. The intent of applying the confidence interval is to avoid
forcing a calibration change based upon insufficient data. After only
one year of data collection, the number of samples in some intervals
will be small, and the confidence interval may be as large as the
tolerance limit. In this instance, the calibration would have to be
extremely poor before a calibration change would be mandated. After the
instrument has been in the calibration program for several years, the
confidence interval should be reduced to approximately 0.05 and
recommendations can be made with greater certainty. The latest three
years of data will be used to make decisions regarding the need to make
a calibration update.

Whenever a calibration update is made, the manufacturer shall re-predict
moisture values using the three most recent years of available raw data
collected by the Type Evaluation Laboratory.

Updated calibrations will be approved based upon the re-predicted
moisture values. Tolerances will be one-half of the Handbook 44
acceptance tolerance and will be applied in 2 % intervals over the
Standard Moisture Range. Tolerances will include the application of a
95 % confidence interval to the maximum tolerance for each 2 % moisture
interval outside the basic 6 % moisture interval.

Additionally, all calibrations must meet the following requirements for
up to three years of available data:

> a\. The difference between the average bias to air oven for all
> samples up to the maximum moisture limit in a given year and the
> average bias to air oven for any other year shall not exceed: 0.90 for
> corn; 0.80 for rice, oats, sunflowers and sorghum; and 0.70 for wheat,
> soybeans, and barley.
>
> b\. The range of year-to-year differences in bias to air oven shall
> not exceed the HB 44 tolerances for three or more consecutive 2 %
> moisture intervals. Only moisture intervals consisting of five or more
> samples per year will be considered for this comparison.
>
> c\. The average calibration bias with respect to air oven shall not
> exceed 0.20 % moisture, calculated using the most recent calibration
> and all available raw data collected within the last 3 years through
> the maximum moisture limit.

Failure to meet the requirements in item a., b., or c. above will cause
a "No Longer Approved for Use" status to be assigned to the affected
grain type(s) on the NTEP Certificate of Conformance (CC) for that
instrument. Calibration coefficients will not be listed for any
calibration failing these requirements.

Until calibrations for NTEP grains have been evaluated successfully,
they shall not be used on NTEP instruments. Calibrations for any of the
NTEP grain types that have not been evaluated (or that a manufacturer
chooses not to provide) will be listed on the CC as "Not Available."

V. Criteria for NTEP Moisture Calibration Review

The following criteria are to be applied along with criteria listed in
Part IV above to verify calibration performance.

Special Considerations for "Multi-Class Calibrations

For Phase II, data for each individual grain class included in a
"multi-class" calibration will be reviewed to determine what
adjustments, if any, are needed.

Data for each individual grain class and the combined data for all grain
classes included in the "multi-class" calibration will be reviewed to
verify calibration performance for each individual grain class and the
combined data.

# Editorial Change to NIST HB 44, Section 5.56. (a) Table S.1.2. and Section 5.57. Table S.1.2. Column Headings to Add a Column for "Grain Class"

**Background:** At its August 2006 meeting, the Sector recommended
changes to both the Grain Moisture Meter (GMM) and Near Infrared Grain
Analyzer (NIR) sections of NIST HB 44 to include criteria applicable to
"multi-class" calibrations. These recommendations were subsequently
adopted by the NCWM for inclusion in the 2008 version of NIST HB 44.

Overlooked in the original recommendations were changes to column
headings to more specifically indicate that the items listed in those
columns include grain "types" or "classes." Following the NCWM Annual
Meeting NIST conducted a review of the Specifications and Tolerances
Committee\'s (S&T) Grain issues. At this review Diane Lee, NIST-WMD,
mentioned the additional changes to Table S.1.2. to add "Class" to the
headings. These changes were judged to be editorial changes not
requiring Sector approval. Steve Cook of NIST, new NCWM S&T Technical
Advisor, and Ms. Lee further modified the tables to improve their
appearance and to clarify the relationship between "Type" and "Class" by
adding columns for "Grain Type" and "Grain Class." Additional changes
were made to the titles in tolerance tables to include "Class." The
modified tables are shown below as they will appear in the 2008 version
of NIST HB 44:

**Accepted:**

a.  In Table S.1.2. of Section 5.56.(a) add a column for "Grain Class"
    as shown below.

# State Responses to Questions in Don Onwiler's Letter to Enhance State Participation in the Grain Analyzer Sector

**Background:** In mid-February 2007, Don Onwiler, NTEP Committee
Chairman, sent a letter to key weights and measures (W&M) officials
seeking their responses to the following questions:

1.  Does your jurisdiction inspect devices for accuracy in test weight
    determination? How is that working out? Are the test procedures and
    tolerances appropriate?

2.  Has your jurisdiction performed inspections of grain analyzers for
    protein content of grain? How has that worked out? If you have not
    done these inspections, is there a reason why? Are there still
    hurdles to clear in NIST Handbook 44?

3.  How are you getting along with the tolerances and test procedures
    for grain moisture?

This was done in an attempt to identify issues of immediate interest to
state W&M personnel; reasoning that an agenda featuring issues that are
of high concern to them would encourage participation by state W&M
personnel. Also, a direct written request from NCWM for assistance on
topics of high concern to them may be helpful when they approach
administrators for travel funds.

Responses to Don's questions were received from six states: Colorado,
Illinois, Maryland, Nebraska, North Carolina, and South Carolina. They
are summarized below:

1.  Four of the six states have been inspecting grain moisture meters
    (GMMs) for Test Weight per Bushel (TW) for several years. An
    additional state will begin this year. The sixth state has been
    unable to collect samples that will test within the tolerances.
    (There may be a misunderstanding regarding samples used for
    testing.) Among the states presently inspecting GMMs with TW
    capability, one reported using a single SRWW sample for this test.
    Another reported that rejection rates for TW dropped from 47.7 % in
    2004 to 12.27 % in 2006, with tests thus far in 2007 at 2.83 %.
    Cheryl Tew, North Carolina Department of Agriculture, suggested that
    it would be helpful if there were procedures for the
    preparation/selection of field test samples. All respondents
    presently inspecting GMMs for TW were of the opinion that test
    procedures and tolerances were appropriate.

2.  None of the six states reported that they were performing
    inspections of NIR grain analyzers measuring protein in grain. Four
    of the six indicated that to the best of their knowledge their
    jurisdictions did not have any commercial meters performing protein
    tests. The fifth gave no reason, but said that they have "no plans
    at this time to conduct inspections on the protein content in
    grain." The remaining state, Colorado, gave several reasons why they
    were not inspecting NIR grain analyzers at present:

```{=html}
<!-- -->
```
a)  **Statutory authority:** The Colorado Measurement Standards Act
    provides for the licensing of grain moisture meters but not for NIR
    grain analyzers.

b)  **Resources:** To implement a grain analyzer for protein (NIR)
    program, we would require more test samples, metrologist and field
    staff training, and additional inspection time. To date we have not
    researched the number of eligible devices in our state.

c)  **Industry input:** We have not yet contacted our industry partners
    for input.

d)  **Handbook 44, Section 5.57. paragraph N.1.2.:** Colorado interprets
    this paragraph to mean that constituent values be assigned to NIR
    test samples by GIPSA. We suspect that purchasing enough samples
    from GIPSA to test all the commercially used devices in Colorado
    would be cost prohibitive.

```{=html}
<!-- -->
```
3.  All six states had no problems with current test procedures and
    tolerances for grain moisture; however, several areas of concern
    were mentioned:

```{=html}
<!-- -->
```
a)  **Testing with high moisture corn** -- difficult to determine if a
    "failed" inspection is due to the meter or the sample.

b)  **Sample preparation** -- some makes of meters agree well with air
    oven on a sample while other makes do not. Is the problem with the
    air oven or is this a normal difference between meter types?

c)  **Testing meter to unlike meter** -- consistent problems approving
    one specific type and a large percentage of rejects of another type.

4.  One state suggested that it might be helpful to do a round robin air
    oven comparison among laboratories.

**Discussion:** The Sector was surprised to learn that field inspections
of NIR grain analyzers were not being performed. When the NIR Sector was
founded, over 15 years ago, there was an indication that there was an
urgent need to develop Handbook 44 Code covering near infrared protein
analyzers. The scope of the Code was later expanded to include near
infrared devices measuring additional grains/oil seeds and additional
constituents. The Near Infrared Grain Analyzer Code was elevated to
permanent status effective January 1, 2003.

Diane Wise, Colorado Department of Agriculture, estimated that there are
100 to 150 NIR instruments in Colorado, mostly used in grain elevators
for determining wheat protein. She reported that letters have been sent
out to survey industry needs and to seek participants in a pilot program
for testing NIR units in the field.

A question was raised regarding how the standard reference samples
needed for field-testing would be provided to the states. It was pointed
out that, at present, states must provide the samples. Paragraph N.1.2.
of the NIR Grain Analyzer Code of NIST Handbook 44 stipulates:

> **N.1.2. Standard Reference Samples.** **--** Reference samples used
> for field inspection purposes shall be clean and selected to
> reasonably represent the constituent range. These samples shall be
> selected such that the difference between constituent values obtained
> using the GIPSA standard reference method and an official GIPSA NIR
> grain analyzer does not exceed one-half of the acceptance tolerance
> shown in Table T.2. for individual test samples or 0.375 times the
> acceptance tolerance shown for the average of five samples.

(Amended 2001and 2003)

Dr. Richard Pierce, GIPSA, did not immediately recall the origin of the
traceability numbers, but suspected they came from the original
Tentative Code that covered only wheat protein. He noted that they would
not apply to soybeans.

The estimated cost of the NIR protein, Combustion Nitrogen Analyzer
(CAN) as-is protein, and air oven moisture tests (based on the
fees/charges listed in USDA/GIPSA/FGIS Directive 9180.74, dated
February 12, 2007) are listed below:

> GIPSA NIR Wheat Protein (at 12 % M.B.) \$10.00
>
> GIPSA Lab Fees/test:
>
> CNA "as is protein" \$16.00
>
> Air Oven Moisture\* [\$13.00]{.underline}

Total per sample \$39.00

> (\*required for reporting protein on a specified moisture basis.)

A minimum of five samples are required for field inspection of devices
measuring protein in wheat. More than five samples might have to be
submitted for testing to assure that at least five samples will meet the
criteria specified in N.1.2.

Because of time constraints, further discussion on this issue was
postponed to a future Sector meeting.

# Report on OIML TC 17/SC 1 IR59 "Moisture Meters for Cereal Grains and Oilseeds"

**Background and Discussion:** This item was included on the Sector's
agenda to provide a summary of the activities of OIML TC 17/SC 1. The
Secretariat (China) is working closely with the United States and a
small international work group (IWG) to revise OIML R 59 "Moisture
Meters for Cereal Grains and Oilseeds." All committee drafts (CD) have
been distributed to the United States National Working Group (USNWG),
which for the most part is a subset of the NTEP Grain Analyzer Sector.

TC 17/SC 1 last met in September 2004 in Paris, France to review
comments to the April 2004 2 CD of OIML R 59. Since that time, revisions
and comments have been handled by mail. A 4 CD dated July 2006 was
received from the Secretariat and circulated to the USNWG in August
2006. U.S. comments were returned to the Secretariat in November 2006.
To assist in identifying and locating changes that had been made to the
3 CD for inclusion in the 4 CD, a copy of the collated comments to the
3 CD from all participating countries was forwarded to the USNWG in May
of 2007.

The U.S. will host the next meeting of TC 17/SC 1 at NIST September 24
and 25, at which time comments on the 4 CD will be reviewed. Diane Lee,
NIST/WMD, briefed the Sector on the status of comments to the 4 CD of
IR 59 and brought the Sector up to date on plans for the TC 17/SC 1
meeting to be held at NIST.

Many of the 172 comments on the 4 CD of IR 59 dealt with formatting or
editorial issues. Major issues brought up in the comments are summarized
below:

+---------+------------------------------------------------------------+
| Japan   | Change scope from "fully automated digitally indicating"   |
|         | to "direct indicating" grain moisture meters.              |
+---------+------------------------------------------------------------+
|         | Remove "The minimum allowable sample size used in analysis |
|         | shall be 100 g or 400 kernels or seeds, whichever is       |
|         | smaller" (or remove resistance type meters from the        |
|         | scope).                                                    |
+---------+------------------------------------------------------------+
|         | Remove requirement that Meters must be equipped with a     |
|         | communications interface.                                  |
+---------+------------------------------------------------------------+
| BIML    | In order to have a complete harmonization of the           |
|         | measurements, it would be appropriate to define an         |
|         | International Reference Method based on ISO Standards. In  |
|         | 4 CD, the reference method for moisture content is defined |
|         | by the national responsible body. Reference Methods should |
|         | be those defined in International Standards (e.g.,         |
|         | ISO 711, ISO 712, ISO 665...).                             |

|         | -   Low voltage of internal battery (OIML D 11 - 14.1)     |
+---------+------------------------------------------------------------+
| BIML    | Testing procedures should specify the number of            |

+---------+------------------------------------------------------------+

Ms. Lee asked Sector members (most of whom are also members of the
USNWG) to review the country comments and provide any reply or concerns
they may have with these comments by September 15, 2007. She will
arrange a conference call with those who plan to attend the TC 17/SC 1
meeting to discuss some of the more important concerns with the
standard.

\[Editor's Update: During the September 24 ‑ 25, 2007, TC 17/SC 1
meeting, the subcommittee members agreed to a number of changes to the
OIML grain moisture Recommendation and addressed a number of the issues
that were reviewed during the Sector meeting. The subcommittee agreed
that:

-   the scope would state that "This Recommendation applies to digitally
    indicating grain moisture meters that directly display moisture
    content,"

-   ISO Standards were recommended but the reference method will still
    be determined by the national responsible body,

-   the sample size of 100 g or 400 Kernels remains in the standard but
    the national authorities may determine otherwise,

-   at least two instruments must be submitted for type approval.

Efforts were made at the meeting to harmonize the OIML grain moisture
Recommendation and the protein Recommendation. The updated grain
moisture Recommendation will be forwarded to the USNWG when updates to
the Recommendation have been completed\].

# Report on OIML TC 17/SC 8 Draft International Recommendation "Protein Measuring Instruments for Cereal Grain"

**Background:** This item was included on the Sector's agenda to provide
a summary of the activities of OIML TC 17/SC 8. The first meeting of
OIML TC 17/SC 8, charged with developing an International Recommendation
(IR) for "Protein Measuring Instruments for Cereal Grain," was held in
Sydney, Australia May 31 ‑ June 1, 2004, to review comments received on
an outline draft that had been developed earlier by Australia, the
Secretariat of TC 17/SC 8. At that meeting, the scope of the
recommendation was expanded to include wheat, barley, corn, soybeans,
and rice, and changes were made to allow the national measurement
authority to determine moisture basis, reference method, instrument
monitoring process, and whether or not to test non-direct measuring
devices.

The U.S. received a 2^nd^ working draft (WD) of this document in
August 2004, and a 3^rd^ draft was received in May 2005. The USNWG
members provided comments to these drafts relating mostly to parts of
the document that appeared to be in conflict with U.S. metrological
practice and procedures. In June 2005, a work group meeting was held in
Berlin to address comments on the 3^rd^ draft. Subsequently, a
1^st^ Committee Draft (CD) of "Protein Measuring Instruments for Cereal
Grain and Oil Seeds" dated May 2006 was forwarded to the USNWG with a
request for comments by July 1, 2006. A second meeting of the work group
was held in Ottawa, Canada in September 2006 to review comments received
on the 1 CD. The main points of contention were: 1) Maximum permissible
errors (MPEs), and 2) the standard reference method (Kjeldahl method vs.
Dumas method). A small working group (WG) was established to consider
appropriate MPEs for protein measuring instruments. A table of proposed
MPEs (see table following) has been distributed to USNWG members for
review and comment by June 25, 2007.

The U.S. will host the next meeting of the TC 17/SC 8 work group at NIST
September 20 and 21, 2007, to attempt to resolve issues related to MPEs
and the standard reference method.

**Discussion:** Diane Lee, NIST/WMD, reported that U.S. comments had
been forwarded to Australia. The U.S. response included a table of the
tolerances that are applied in the U.S. type evaluation program for
protein measuring instruments and also field evaluation tolerances and
an explanation of how the tolerances are applied. As of the August 2007
Grain Analyzer Sector meeting, no response had been received from
Australia.

\[Editor's Update: Australia's reply to comments on the Table of
Proposed MPEs was received in the U.S. approximately one week after the
Grain Analyzer Sector meeting. The reply was distributed to members of
the USNWG requesting comments or feedback by September 15, 2007. In
summary, Australia's reply indicated that they were firmly opposed to
separate MPEs for repeatability and reproducibility and to the further
separation of MPEs for particular instrument characteristics. However,
they would support the inclusion of tight MPEs for repeatability, but
they are yet to be convinced that there is any need for MPEs for
reproducibility.\]

\[Additional Editor's update: During the September 20 ‑ 21, 2007,
TC 17/SC 8 meeting, Australia and other members of the subcommittee
agreed to add additional tests and separate MPEs for these tests to the
OIML Protein Recommendation. An updated OIML Protein Recommendation with
changes from the September 20 ‑ 21, 2007, TC 17/SC 8 meeting will be
circulated to the USNWG when the U.S. receives the updates from the
Secretariat.\]

# Report on OIML TC 5/SC 2 Draft "General Requirements for Software Controlled Measuring Devices" and NTETC Software Sector Activities

**Background:** This item was included on the Sector's agenda to provide
a summary of the activities of OIML TC 5/SC 2 and the NTETC Software
Sector. In 2004, all OIML TCs and SCs that were revising an OIML
Recommendation were contacted to ensure that software aspects would be
considered in revised Recommendations. All OIML Documents and
Recommendations published since 1990 have been reviewed for terms and
requirements related to software. A pre-draft of the document "Software
in Legal Metrology" was circulated in October 2004 by the
Co-Secretariats (Germany and France). When complete, this document will
serve as guidance for OIML technical committees addressing software
requirements in Recommendations for software-controlled instruments.
NIST submitted U.S. comments on an early draft in February 2005. The
1^st^ working draft (WD) of this document, titled "General Requirements
for Software Controlled Measuring Instruments" was received in
February 2006. U.S. comments to this WD were sent to the Secretariat in
June 2006. A 1^st^ Committee Draft (CD), addressing comments received on
1 WD, was recently distributed by the Secretariat. Copies (in pdf
format) are available at <http://www.oiml.org/download/cds.html>.

The NTETC Software Sector held its first meeting in April 2006. At that
time, several subcommittee work groups were formed to focus on various
aspects relating to the use of software in today's weighing and
measuring instruments. A second meeting was held in October 2006.

**Discussion**: Diane Lee, NIST/WMD, reported that Ambler Thompson of
NIST-WMD has requested that any U.S. comments on 1 CD should be sent to
him no later than September 7, 2007. The next meeting of TC 5/SC 2 is
scheduled to be held at the PTB in Berlin, Germany during the week of
December 3 ‑ 7, 2007. Comments to 1 CD will be addressed at that time.

The NTETC Software Sector held its third meeting May 7 ‑ 8, 2007, in
Sacramento, California. Their next meeting is tentatively scheduled for
the spring of 2008, either immediately preceding or following the
meeting of NTEP laboratory representatives held at that time. Steve
Patoray, NTEP Director, reported that the WELMEC document for Type P
(built-for-purpose) and Type U (using a universal general-purpose
computer) instruments is being used as a model for much of the Software
Sector's proposed Code.

\[Editor's Note: A history and overview of WELMEC activities towards the

# Enhanced Trait Soybeans -- Calibration Issues

**Source:** United Soybean Board (USB)

**Background:** Near infrared analyzers are becoming increasingly
necessary for measuring soybean composition factors. In some cases, the
factors are those covered by NTEP (protein and oil) and in others the
factors are outside NTEP (individual fatty acids, sugar profiles, and
others). Successful development of new traits requires uniform
measurements across the entire developmental chain, from seed breeder to
end user, a broader scope than covered by NIST Handbook 44. Additional
instruments beyond those actually submitted for NTEP are used;
collectively all instruments across the development chain need to agree,
both on average, and, to the extent possible, from sample to sample.

Two United Soybean Board projects, Soybean Quality Traits (SQT) and
Analytical Measurements and Marketing Standards Initiative (AMMS) have
been developing a program that would generate a common soybean sample
pool (with reference chemistry) that could be used to:

1.  Modify existing instrument calibrations of all manufacturers
    (whether NTEP participants or not) such that differences among them
    are minimized.

2.  Allow new manufacturers/technologies to enter the market
    efficiently.

3.  Form the basis for a voluntary-participation proficiency program
    open to any user at any point in the development chain, many of
    which would not be subject to Handbook 44.

4.  Allow rapid evaluation and introduction of tests for new traits,
    such as amino acids, phytate, fatty acid profiles. This would
    include the measurement of general market factors (protein and oil)
    on specialty grains that likely were not in the calibration pool of
    the NTEP calibrations.

The overall goal is to facilitate the introduction of new technologies
and new traits in an organized way that supports the more direct supply
chain markets developing from bioprocessing and biotechnology.
Activities of the two USB projects could provide both support and sample
materials for the NTEP program.

**Discussion:** Participants in the SQT and AMMS projects will share
results and future concepts for cooperation with the Grain Analyzer
Sector. Some of the topics include:

1.  Should we bring new traits more quickly into the NTEP system, and if
    so, how can the USB programs assist?

2.  Can we harmonize sample pools?

3.  Is there a way to collaborate to gain participation in NTEP of
    instruments not necessarily designed/marketed for trade use, but
    that still are integral parts of the value chain (i.e., those
    designed for breeder use).

4.  How to harmonize contractual trades as well as those subject to open
    market regulation - especially when NTEP factors may be measured
    along with others, but on specialty rather than general market
    grains.

5.  How to update NTEP calibrations to measure the general market
    factors on new genetics not likely to be found in open market
    channels.

Amy Lopez, AOCS, manager of the USB SQT Analytical Standards Program,
summarized efforts underway on the development and evaluation of
analytical tools for the analysis of soybean quality traits. These
efforts involve both wet chemistry and NIR analyzers. Work is being done
with mulitple NIR companies to improve calibrations not only for protein
and oil, but also for fatty acids and amino acids. Toward this end, a
sample library, representative of many of the new genotypes, is being
maintained. Assistance is offered to NIR manufacturers by supplying
samples for calibration development. Calibration files developed in the
SQT Analytical Standards Program (with yearly calibration updates) are
offered to NIR device users. Also included is the opportunity to take
advantage of a QC program in which the same prepared sample is sent to
all participating laboratories to obtain specific analytical results.
After performing the required analyses a participaing laboratory returns
the results to AOCS which provides a statistical evaluation of the
analytical results that compare, on a confidential basis, that
laboratory\'s data with those of the other participating laboratories. A
submitting laboratory's identity is known only to the submitter.

Dr. Nick Bajjalieh, Integrative Nutritition, Inc., outlined the approach
the USB AMMS program was taking to develop marketing initiatives
especially in the animal feed area.

Following the presentations, it was pointed out that most of the
suggested topics were outside of the Sector's scope. However, several
Sector members agreed that all NIR instruments in commercial use should
be capable of providing in-tolerance results for protein, oil, and
moisture when tested using the same soybean sample, whether that sample
is a commodity-type soybean variety or a so-called "enhanced trait"
variety. In other words, protein, oil, and moisture measurements using a
"specialty soybean calibration" should agree with protein, oil, and
moisture measurements using an NTEP soybean calibration. As more
"enhanced trait" varieties are introduced, it is inevitable that some
will find their way into commodity soybean channels, so harmonization of
soybean protein, oil, and moisture calibrations between NTEP
calibrations and "Enhanced Trait" calibrations should be a goal.

Dr. Pierce noted that GIPSA is expanding their NIR calibration database
to include some specialty trait grains.

# Prevention of Potential GMM Fraud -- Expected Integrity among Moisture Meter Manufacturers

**Source:** DICKEY-john Corporation

**Background:** This item is intended to call attention to the
potentially fraudulent practice of "calibrating" field instruments to
read differently (higher) than like-type NTEP meters in the grain
moisture meter (GMM) Ongoing Calibration Program (OCP) at GIPSA in
Kansas City, thereby encouraging elevator owner-operators to purchase
meters reading higher than the Federal Standard moisture meter. This
issue has recently surfaced again due to seasonal grain movement in
commercial corn markets.

For years, certain manufacturers or service agencies have been suspected
of performing fraudulent electronic calibration adjustments to grain
moisture meters before returning them to the field after repair or
periodic routine maintenance. In fact, many like-type commercial
moisture meters in field use have been noted to read (consistently) at
the high end of the maintenance tolerance for moisture, thus allowing
them to read several tenths to full percentage points higher in
moisture, during commercial grain trade, than the GAC2100 Federal
Standard meter. Grain purchased using a meter reading higher, inaccurate
moisture values costs producers money in terms of inflated drying
charges and excess shrinkage, thus benefiting the buyer. This same grain
can then be sold by the buyer using a different meter (one that reads
lower moisture) without incurring excess shrinkage or inflated drying
cost, affording the buyer (now seller) an unfair profit at the cost of
the producer.

This alleged fraudulent practice has been noted due to the fact that
comparative OCP data for Corn identifying the Official Meter and listing
the average bias for each NTEP meter type published by the NTEP
Participating Laboratory for Grain Analyzers in 2005 and 2006 clearly
show the Official Meter (the DICKEY-john GAC2100) to agree within 0.2 %
moisture with any other NTEP meter up to 20 % moisture. Above 20 %
moisture, the GAC2100 moisture indication increases to over 0.4 %
moisture above other NTEP meters and peaks to 1.3 % moisture above most
other meters at 27 % moisture. These data would indicate that most
*field* meters should consistently read the same as the Federal Standard
meter below 20 % moisture and below the Federal Standard meter at
moistures higher than 20 %. However, state regulatory field test results
for Corn (crop years 2005 and 2006) appear to indicate that the opposite
may be true.

There are several NIST HB 44 requirements that speak to the maintenance
and use of devices that are intended to prevent the user from taking
advantage of the tolerance of any device. The general code in HB 44
includes the following pertinent paragraphs:

> **GUR.4.1 Maintenance of Equipment**
>
> This paragraph states that, *"\...Equipment in service at a place of
> business found to be in error predominately in a direction favorable
> to the device user shall not be considered maintained in a proper
> operating condition."* Although this does not speak directly to
> moisture meters, its intent is to ensure that when devices are
> calibrated, the calibration is set as close to zero as possible and is
> not set to one side of the tolerance in favor of the device owner.
>
> **GUR.4.3 Use of Adjustments**
>
> This paragraph states that "...*Whenever equipment is adjusted, the
> adjustment shall be so made as to bring performance as close as
> practicable to zero value*."
>
> **Fundamental Considerations, NIST HB 44, paragraph 2.3 Tolerance and
> Adjustments**
>
> "...*Equipment owners should not take advantage of the tolerances by
> deliberately adjusting their equipment to have a value or to give
> performance at or close to the tolerance limit\..."*

There are also provisions for avoidance of perpetration of fraud found
in NIST Handbook 130 Uniform Laws and Regulations:

> **Section 15, Misrepresentation of Quantity**
>
> "*No person shall: sell, offer, or expose for sale a quantity less
> than the quantity represented, nor* *take more than the represented
> quantity when, as buyer, he/she furnished the weight or measure by
> means of which the quantity is determined, nor* *represent the
> quantity in any manner calculated or tending to mislead or in any way
> deceive another person."*
>
> **Section 22, Prohibited Acts**
>
> *"No person shall use or have in possession for use any incorrect
> weight or measure\..."*

The above information is not intended in any way to accuse or insinuate
that any particular meter manufacturer is knowingly participating in
fraudulent practices, but is intended to provide information regarding
the regulations designed to prevent such potential occurrences.
Reviewing these regulations is intended to remind manufacturers and
their service agencies that intentionally adjusting meters *to be in
error predominately in a direction favorable to the device user* is
considered a fraudulent practice, and also to remind weights and
measures officials that meters adjusted in this manner *shall not be
considered maintained in a proper operating condition.*

**Discussion:** Questions were raised about the validity of the 2002
study in Illinois, especially with regard to the use of high-moisture
corn samples (above 22 % moisture), many of which were so wet that they
had to be hand-shelled. Responding to the question, "How do you prove
that production does or does not meet type?" Dr. Richard Pierce, GIPSA,
noted that because different meter types react differently to the same
sample, the only way to show conformance to type is by a
meter-to-like-meter comparison where the "standard" meter is traceable
to the meters in the NTEP Phase II program at GIPSA. Steve Patoray, NTEP
Director, suggested that this may be an enforcement issue, not a
conformity issue. As such, this type of issue should be discussed at a
regional meeting. Co‑Technical Advisor, Jack Barber, offered the opinion
that it is a standardization or normalization issue. If a difference
does exist between the NTEP "standard" meters and a device in the field,
it could be due to improper adjustment either by the manufacturer or by
a service agency. It was suggested that states may need to ensure that
there is a Registered Service Agent program in the state and that
service personnel receive the proper training to ensure that adjustments
made to the meter are appropriate.

The Sector took no action on this issue.
