# Report on the Activities of the OIML Technical Committees

This section reports on recent activities and the status of work in OIML
Technical Committees (TCs) and Technical Subcommittees (SCs) of specific
interest to members of NCWM. Also included are schedules of future
activities of the Secretariats, the U.S. National Work Groups (USNWGs),
and the International Work Groups (IWGs) of the Committees and
Subcommittees.

*TC 3/SC 1 "Pattern Approval and Evaluation" (United States)*

The subcommittee approved the U.S. proposal for a combined revision of
OIML D 19 "Pattern evaluation and pattern approval" and D 20 "Initial
and subsequent verification of measuring instruments and processes" into
a single document entitled "Principles of metrological control of
measuring instruments: type approval and verification." Key elements of
OIML D 3 "Legal qualification of measuring instruments," R 34 "Accuracy
classes of measuring instruments," and R 42 "Metal stamps for
verification officers" will also be incorporated into the combined
revision of OIML D 19 and D 20. The revised documents will incorporate
recent developments such as the OIML certificate system, D 27 "Initial
verification of measuring instruments utilizing the manufacturer\'s
quality management system," and the "Framework for a mutual acceptance
arrangement (MAA) on OIML type evaluations." Consideration will be given
to the appropriate conformity assessment options developed by the ISO
Council Committee on Conformity Assessment (ISO CASCO), including
quality systems, product certification, and accreditation. Consideration
will also be given to information technology and statistical methods to
increase or decrease verification intervals based upon proven instrument
performance. For more information on this activity, contact Dr. Ambler
Thompson at (301) 975‑2333 or at <ambler@nist.gov>.

*TC 3/SC 5 "Conformity Assessment" (United States and BIML)*

The subcommittee plans a meeting May 27 - 30, 2008, to begin revision of
the documents B3 (Certificate System) and B10 (MAA). The meeting will
also include discussion of a new document on the incorporation of
measurement uncertainty into conformity assessment decisions in legal
metrology. For more information on this activity, contact Dr. Charles
Ehrlich at (301) 975‑4834 or at charles.ehrlich@nist.gov.

*TC 5/SC 2 Software (Germany and BIML)*

A 1 CD of OIML \"General requirements for software-controlled measuring
instruments\" was received in June 2007 and circulated to the NCWM
Software Sector and other interested U.S. parties. The U.S. comments on
the 1 CD were submitted to the International Secretariat in September
2007. There will be a meeting of the OIML Software subcommittee in
Berlin in December 2007. When complete, the OIML document will serve as
guidance for software requirements in International Recommendations by
OIML technical committees. The ILMG participated in NCWM Software Sector
meetings in Little Rock, Arkansas, and Lake Tahoe, California, in
October and May 2007, respectively. Please contact Dr. Ambler Thompson
at (301) 975‑2333 or at <ambler@nist.gov> if you would like to receive
information and participate in this project.

*TC 8/SC 1 "Static Volume and Mass Measurement" (Austria and Germany)*

The subcommittee Secretariat plans to have three documents completed and
ready for a CIML postal ballot in 2008: OIML R 71 "Fixed storage tanks,"
R 80 "Road and rail tankers," and R 85 "Automatic level gages for
measuring the level of liquid in fixed storage tanks." The Secretariat
circulated a 3 CD for R 80 in November 2006 and a 3 CD of R 85 in
December 2006. U.S. vote and comments on R 80 and R 85 were returned in
February 2007, and a subcommittee meeting was held in March 2007 in
Vienna, Austria. Progress was made on all three documents in Vienna. A
3 CD of R 71 was received in July 2007, and a 4 CD of R 85 was received
in August 2007. Please contact Ralph Richter at (301) 975‑3997 or at
<ralph.richter@nist.gov> if you would like copies of the documents or to
participate in any of these projects.

*TC 8/SC 3 "Dynamic Volume and Mass Measurement for Liquids other than
Water" (United States and Germany)*

OIML R 117‑1 "Dynamic measuring systems for liquids other than water,
Part 1: Metrological and technical requirements" has undergone an
extensive revision. The Recommendation obtained 100 % international
"yes" votes and final CIML approval at the CIML meeting in Shanghai,
China, in October 2007. The revision incorporates new instrument
technologies and includes a merger with OIML Recommendations R 86 "Drum
meters" and R 105 "Mass flowmeters." After publication of R 117‑1,
Recommendations R 86 and R 105 will be withdrawn. The ILMG has worked
closely with the USNWG on flowmeters, Germany, and the Netherlands on
this effort. Meetings of the USNWG on flowmeters were held during the
NCWM Interim Meeting in January 2007 in Jacksonville, Florida, and the
NCWM Annual Meeting in July 2007 in Utah. Measurement Canada has also
been a strong contributor to this effort. Subcommittee work on R 117‑2
"Test methods" and R 117‑3 "Test report format" has begun. If you have
any questions, would like a copy of the R 117‑1 DR, or would like to
participate in the next phases of this project, please contact Ralph
Richter at (301) 975‑3997 or <ralph.richter@nist.gov>.

*TC 8/SC 6 "Measurement of Cryogenic Liquids" (United States)*

In July 2007 the Secretariat (U.S.) requested that Participating members
and U.S. stakeholders decide if there was sufficient justification for
opening a new project to revise R 81 "Dynamic measuring devices and
systems for cryogenic liquids." The response received by the Secretariat
indicated that a revision of R 81 was justified to update:
(1) electronic tests in accordance with the latest edition of OIML D 11
(2004) and/or the latest IEC and ISO standards; (2) technical
requirements to include new developments in hydrogen measurements;
(3) Annex C to include current recommendations for density equations;
and (4) existing sections into three distinct parts similar in format to
recently-developed OIML Recommendations.

Subsequently, the Secretariat submitted a proposal to the BIML
requesting approval for the start of a new project to revise R 81. The
BIML submitted the proposal at the October 2007 42^nd^ Meeting of the
CIML and was granted approval of the project. The Secretariat will ask
members of TC 8/SC 6 to review and formally comment on R 81. The
Secretariat will form a National Work Group to establish a U.S. position
on the appropriate updates to the document by spring 2008. To obtain
more information or to participate in this project, please contact Juana
Williams at (301) 975‑3989 or <juana.williams@nist.gov>.

[]{.mark}

*TC 8/SC 7 "Gas Metering" (Netherlands)*

In October 2007, the CIML approved the merger of TC 8/SC 7 (with France
and Belgium as co-secretariats) and TC 8/SC 8 "Gas meters" (with
Netherlands as secretariat). Netherlands has assumed responsibility of
this newly merged technical subcommittee. In April 2007, a DR of the new
Recommendation "Measuring systems for compressed natural gas (CNG) for
vehicles" was circulated with annexes covering performance tests for
electronic devices and basic test procedures. The postal ballot on this
Recommendation failed, but the Recommendation was approved by the CIML
in October 2007. The United States voted "no" on both the postal ballot
and at the CIML meeting because some of the system testing requirements
were considered to be excessive and very expensive.

Also in April 2007 a postal ballot was circulated on another new
Recommendation "Measuring systems for gaseous fuel" and U.S. comments
were submitted in June 2007. This Recommendation is intended for large
pipelines with large flow rates and high operating pressures. The postal
ballot on this Recommendation also failed, but the Recommendation was
approved by the CIML in October 2007.

The final draft of OIML R 137‑1 "Gas meters" was approved by the CIML at
their October 2006 meeting in Cape Town, South Africa. Published in
2007, OIML R 137‑1 combines and replaces three old Recommendations that
will soon be withdrawn: R 6 "General provisions for gas volume meters,"
R 31 "Diaphragm gas meters," and R 32 "Rotary piston gas meters and
turbine gas meters." Development of R 137‑2 "Test methods" is now
underway. Please contact Ralph Richter at (301) 975‑3997 or
<ralph.richter@nist.gov> if you would like to obtain a copy of any of
these gas measurement documents or if you would like to participate in
future work of this subcommittee.

[]{.mark}

*TC 9 "Instruments for Measuring Mass" (United States)*

The Secretariat to OIML R 60, "Metrological regulation for load cells"
(U.S.) will send a questionnaire to the members of OIML TC 9 and the
USNWG requesting input on whether or not to recommend a project be
established to revise R 60 once the final version of R 76 is published.
The questionnaire will ask for feedback on everything from the basic
principles of R 60 (e.g., tolerances and accuracy classes) to exploring
the addition of new requirements. For more information on these efforts,
please contact Steve Cook at (301) 975‑4003 or <steven.cook@nist.gov>.

*TC 9/SC 1 "Nonautomatic Weighing Instruments" (Germany and France)*

The revision of R 76 "Non-automatic weighing instruments" is of major
importance to U.S. interests because the Recommendation serves as the
foundation for a majority of the laws and regulations that govern
weighing instruments around the world. The revision includes new
language addressing metrological controls for type evaluations,
conformity, initial and subsequent inspections, suitability of separable
components and requirements for metrological software. The USNWG was
consulted concerning proposals to harmonize NIST Handbook 44 and R 76.
As reported at the 2007 NCWM Interim Meeting, the DR of R 76‑1 was
approved by the CIML in October 2006. Most recently, the United States
voted "yes" on the DR of R 76‑2 "Test report format." It is anticipated
that the revision of R 76 will be published and posted on the OIML
website prior to the 2008 NCWM Interim Meeting. For more information on
these efforts, please contact Steve Cook at (301) 975‑4003 or
<steven.cook@nist.gov>.

[]{.mark}

*TC 9/SC 2 "Automatic Weighing Instruments" (United Kingdom)*

The Recommendation R 134‑1 "Automatic instruments for weighing road
vehicles in motion -- total load and axle weighing" was approved by CIML
in October 2006 with the agreement that U.S. comments concerning
terminology and document scope were to be incorporated before
publication. The test report format of this document, R 134‑2, has been
approved by the subcommittee and is going through a final editorial
process at the BIML.

The 3 CD of R 106 Parts 1 and 2, "Automatic rail‑weighbridges" were
distributed by the Secretariat to members of TC 9/SC 2 on
September 25, 2007. Comments and vote are due February 11, 2008. In
distributing the 3 CD, the Secretariat commented that although the 2 CD
achieved majority approval, there were substantial comments and some
amendments to the technical requirements of the 2 CD which did not make
the draft suitable for issue as a Draft Recommendation. The subcommittee
approved a revision of R 107 "Discontinuous totalizing automatic
weighing instruments (totalizing hopper weighers)," and approval was
granted on the 1 DR at the October 2007 42^nd^ Meeting of the CIML. If
you would like to receive copies of these documents or work on these
projects, Richard Harshman is the contact at (301) 975‑8107 or at
<harshman@nist.gov>.

*TC 17/SC 1 "Humidity" (China)*

The Secretariat (China) is working closely with the United States and a
small IWG to revise OIML R 59 "Moisture meters for cereal grains and
oilseeds." All drafts have been distributed to the USNWG, which for the
most part is a subset of the NTEP Grain Sector. A 4 CD was circulated to
the IWG in August 2006. U.S. comments on the 4 CD were returned to the
Secretariat in November 2006. A TC 17/SC 1 meeting was hosted by NIST in
September 2007 to discuss the comments to the 4 CD. At the TC 17/SC 1
September 2007 meeting, the subcommittee also discussed harmonization of
the Recommendation for moisture with the TC 17/SC 8 subcommittee's
Recommendation for protein. Please contact Diane Lee at (301) 975‑4405
or at <diane.lee@nist.gov> if you would like to participate in this work
group.

[]{.mark}

*TC 17/SC 8 "Quality Analysis of Agricultural Products" (Australia)*

A new subcommittee has been formed to study the issues and write a
working draft document "Measuring instruments for protein determination
in grains." Australia is the Secretariat for this new subcommittee. A
work group meeting was held in September 2006 in Ottawa, Canada, to
discuss comments on the 1 CD. A TC 17/SC 8 meeting was hosted by NIST in
September 2007 to discuss the 2 CD. At the September 2007 meeting the
TC 17/SC 8 subcommittee also discussed comments concerning the maximum
permissible errors (MPEs) and harmonization of the TC 17/SC 8
Recommendation for protein with the TC 17/SC 1 Recommendation for
moisture. Please contact Diane Lee at (301) 975‑4405 or at
<diane.lee@nist.gov> if you would like to participate in this work
group.

**OIML Mutual Acceptance Arrangement (MAA)**

# Report on the 42^nd^ CIML Meeting in Shanghai, China, October 24 - 26, 2007

The International Committee of Legal Metrology (CIML) opened with
addresses given by Mr. Li Chuanqing, Minister of the General
Administration of Quality Supervision, Inspection and Quarantine of the
People's Republic of China (AQSIQ), Mr. Zhou Taitong, Deputy Mayor of
Shanghai, and Mr. Alan E. Johnston, CIML President. A quorum was reached
as 48 Member States out of 59 were present or represented at the
meeting.

The Committee noted that two new Corresponding Members, the United Arab
Emirates and Sudan, had joined the OIML in the past year.

The CIML gave final approval to the following publications in China:

-   Combined Revision of R 4, R 29, R 45 and R 96 "Vessels for
    commercial transactions"

-   Combined Revision of R 117, R 105 & R 86 "Dynamic measuring systems
    for liquids other than water, Part 1: Metrological and technical
    requirements"

-   New OIML Recommendation "Compressed gaseous fuel measuring systems
    for vehicles" (the United States and the Netherlands voted "no" on
    this document, based on input from industry; also see below about a
    new work project to immediately begin revising this document)

-   New OIML Recommendation "Measuring systems for gaseous fuel"

-   Revision of R 21 "Taximeters"

-   Revision of R 107‑1 "Discontinuous totalizing automatic weighing
    instruments (totalizing hopper weighers), Part 1: Metrological and
    technical requirements -- Tests, and Part 2: Test report format"
    (the United States voted "yes", but indicated that the "automatic
    zero-tracking feature" is not permitted in the United States)

-   Revision of R 35 "Material measures of length for general use,
    Part 1: Metrological and technical requirements"

-   Amendment 2 to D 2 "Legal units of measurement"

The CIML took action on the following publications:

-   Recommendation R 24 "Standard one meter bar for verification
    officers" was re-confirmed

-   Document D 4 "Installation and storage conditions for cold water
    meters" was withdrawn

The CIML approved the following new work projects:

-   Project to revise R 79 "Labeling requirements for pre-packaged
    products"

-   Project to revise R 81 "Dynamic measuring devices and systems for
    cryogenic liquids"

-   Project to revise R 66 "Length measuring instruments"

-   Project to revise the new OIML Draft Recommendation "Compressed
    gaseous fuel measuring systems for vehicles"---a new work item in
    (the newly merged) TC 8/SC 7. (This revision should address U.S.
    concerns about this document.)

The CIML also approved the following proposals in China:

-   Proposal to merge subcommittees TC 8/SC 7 Gas metering and TC 8/SC 8
    Gas meters, with the Netherlands as the Secretariat of the combined
    subcommittee

-   Proposal to reallocate the responsibility for Measuring Container
    Bottles from TC 8 to TC 6.

The Committee noted efforts by the [Conformity to Type Work
Group]{.underline}. The WG is in the early stages of developing a
project to study the issue of conformity to type on a global basis. The
WG conducted two surveys on the subject in the past year, but survey
results have thus far proved to be inconclusive as to how OIML should
proceed on this. Further study will proceed. A few countries have
indicated they will be conducting some tests about this, although this
is not a formally sanctioned OIML activity.

[]{.mark}

The Committee also took note of a presentation given by the BIML
Director concerning the development of the first draft tables of
correspondence between OIML Recommendations and the applicable
requirements in the European [Measuring Instruments Directive
(MID)]{.underline}. The Bureau plans to continue its cooperation with
WELMEC on this issue and requested the European participants of the
appropriate TCs/SCs to assist in this effort as soon as a Recommendation
reaches DR status.

The CIML presented Awards to the following individuals in recognition of
their outstanding contribution to legal metrology:

-   Mr. Romain Eggermont (Belgium)

-   Mr. Gerard Lagauterie (France)

-   Mr. Wayne Stiefel (United States)

-   Mr. Ali Tukai (Tanzania)

-   Mr. Bruno Vaucher (Switzerland)

It also gave Letters of Appreciation to:

-   Mr. Peter Brandes (Germany)

-   Dr. Charles Ehrlich (United States)

-   Mr. Mikhalchenko Vassily Nikolaevich (Kazakhstan)

# Future OIML Meetings

The 13^th^ OIML Conference and the 43^rd^ CIML Meeting will be held in
Sydney, Australia, in October 2008, and the CIML accepted Kenya's
invitation to hold the 44^th^ CIML Meeting in 2009.

# Regional Legal Metrology Organizations

[Meeting of the SIM General Assembly]{.underline}

The SIM General Assembly was held in Ottawa, Canada, in September 2007.
Dr. Huberto S. Brandi, Director of Scientific and Industrial Metrology
(SIM) at INMETRO Brazil, is the SIM President (elected last year).
