1. Introduction of the participants
The
Chair of SIM TC Steve Carpenter opened the
meeting at 9:00 am. This was followed by
the introduction of each participant. A
list of the attendees is provided above.
2. Welcoming message from the President
of SIM
Léa
Contier de Freitas provided a welcoming
message in behalf of the president of SIM,
Marco Antônio Araújo Lima
3. Status report and activity plans
for 2000 from metrology working groups
The
chairs of the 10 SIM Metrology Working Groups
(or their representatives) provided status
reports on 1999 activities, reported on
expenditures of their allocations, and briefly
discussed their plans for 2000. Individual
reports are enclosed at the end of this
report. What follows are highlights of discussions
which took place during the TC meeting and
that are not covered by the MWG reports.
During
the MWG-Length presentation, Jim Pekelsky
briefly explained their efforts towards
the development of guidelines for CMC submissions.
These Guidelines were translated to Spanish
by Emilio Pito (CEM-Spain). Hratch Semerjian
asked that the document be made available
to other MWG in electronic archival form.
Alan Robertson seconded Semerjian's suggestions
and commended Pekelsky for his extensive
efforts towards the development of the guidelines.
Semerjian further suggested that the guideline
document be maintained at a central location
like a web site. Bob Watters explained that
the document will be available as part of
the SIM database. Greg Rosasco inquired
regarding the manpower effort required for
the development of the guidelines. Pekelsky
explained that writing the guidelines required
a large portion of the last CCL meeting
(group effort) plus three additional weeks
of Pekelsky's time to finalize it.
Bruce
Field suggested that guidelines for MWG-Electricity
should be easier to develop given the widespread
use of common terminology among all the
SIM labs. Pekelsky explained that the guidelines
are useful for more that developing common
terminology; they help group common standards
and provide means by which to code CMC entries.
He further explained that this is important
given the wide range of technological capabilities
among the various laboratories in SIM. Pekelsky
added that the guide provides a traceability
chain that point at the "main services"
and how the rest are supported by quality
systems.
During
the presentation of the MWG-Ionizing Radiation,
Alan Robertson explained that most SIM countries
provide services at institutions other than
their NMIs. Various participants pointed
out that this is supported by rule 6.1 of
the MRA. It was also mentioned that the
International Atomic Energy Agency (IAEA)
is a signatory of the MRA that their members
could participate in Key Comparisons through
them. Léa Contier de Freitas, who has been
in contact with the IAEA, explained that
IAEA have a well-established program of
standard intercomparisons. Robertson added
that Kent Shortt (NRC-Canada) is working
with Pedro Andreo of the IAEA to make use
of the IAEA comparison structure. Léa Contier
de Freitas mentioned that Brazil would like
to expand the current program of intercomparisons
to cover test of additional radiation standards
currently not considered
The
subject of non-NMI participation in SIM
activities was discussed as part of the
MWG-Flow presentation. Pedro Espina highlighted
the current situation of many SIM NMIs who
have limited calibration measurement capabilities
in the areas of flow metrology. In some
cases, a number of the missing calibration
capabilities can be founded in non-NMI laboratories
within each country. Espina asked for clarification
on the inclusion criteria for non-NMI laboratories.
Following some discussion, Ismael Castelazo
summarized the SIM-TC position by stating
"the inclusion criteria for non-NMI laboratories
is an internal matter state that should
be deal with by each country independently".
It was agreed that once the selection the
non-NMI laboratory has been made, the NMI
is responsible for informing the SIM-TC
of its selection. Bob Watters explained
that the CIPM database provides for such
inclusions and that in such cases, the name
non-NMI laboratory is accompanied by the
name of the NMI (in parenthesis) to explicitly
indicate the association. Janusz Lusztyk
remained the committee SIM-TC that the NMIs
retain final responsibility for the performance
of their non-NMI laboratories as far as
the MRA is concerned.
4. Discussion on the SIM procedure for
review of CMCs
Alan
Robertson initiated the discussion by providing
some historical perspective on the development
of the procedure. Robertson explained how
initially, Steve Carpenter suggested the
development of declaration of measurement
capabilities as documents that could reinforce
the position of some member NMIs. Subsequently,
Robertson developed a generic format for
such declarations and termed it DMRs for
short.
Robertson indicated that Luis Mussio (LATU)
had suggested some minor changes (editorial
in nature), but NIST offered extensive modifications
just prior to the start of the SIM-TC meeting.
Robertson proceeded to discuss each modification
to the document offered by NIST, while trying
to build consensus among the various NMI's
represented at the meeting. In the end,
Robertson was publicly commended by the
SIM-TC chair for its extensive efforts towards
the development of a general procedure and
the attendees concurred with Carpenter by
providing Robertson with a round of applause.
It was agreed that Hratch Semerjian will
help Robertson wordsmith the final procedure
based on the suggestions provided by the
attendees to the meeting. Electronic versions
of the revised document will be circulated
for final comments prior to adoption.
5. Presentation of proposed format for
chemical CMC entries
Willie
May presented two formats under consideration
for the inclusion of Chemical CMCs in the
CIPM database. The first document was developed
by the BIPM while the other is a modification
sponsored by NIST. May explained the added
benefits of the NIST format and suggested
that it be adopted by SIM. The SIM-TC accepted
with May's recommendation and adopted the
NIST proposed format. Furthermore, May was
asked to indicate the SIM preference of
the NIST document on future conversations
at the CIPM level.
6. Discussion on SIM's MRA Appendix
C entries
Alan
Robertson initiated the discussion on the
available CMC submissions. It was clear
that if SIM is going to satisfied the JCRB
imposed schedule, NIST will need to submit
its own capabilities and provide comments
on the submissions of other NMIs, by COB
on Friday, January 28, 2000. Once all SIM
submissions are available on the 28th of
January, the MWG chairs will have 3 working
days to respond to them. The CMCs will then
be sent to the SIM-TC Chair for immediate
distribution to the other members of the
SIM-TC. The SIM-TC will then have one week
to respond back to the Chair prior to the
CMCs been send to the JCRB.
It was agreed, that during this process,
inconsistencies will be broad to the attention
of the particular NMI privately, and only
in cases where disputes can not be settle
within the time available, the CMCs will
be flagged by the MWGs. These flags should
be accompanied by suggestion, which could
help the flagged NMI to expediently solve
the inconsistencies.
It was requested that each MWG submits two
documents to the SIM-TC: a Microsoft Excel
Workbook (one Worksheet per NMI), and a
Microsoft Word document stating the justifications
for the CMC claims. The Chairs of the MWG
are asked to make use of the format provided
by the MWG-Length. This format makes use
of filenames and creation dates as means
of tracking down changes made to each document.
NMIs are encouraged to send correction and/or
comments only to the MWG chairs to avoid
large email traffic among the members; the
Chairs of the MWG will redistribute documents
as deemed appropriate. Those countries that
had previously submitted DMRs can continue
to use them as justifications for their
claims.
7. Discussion on SIM's MRA Appendix
B entries
Bob
Watters announced that the electronic CIPM
database is available at the BIPM web site
(http//www.bipm.fr) and it is also mirrored
at the NIST web site (http://icdb.nist.gov/).
Participants agreed that the MWGs will submit
their supporting evidence to the SIM-TC,
who after reviewing it, will forward the,
to the JCRB. There were question on how
the Consultative Committees will voice their
opinions in the matter. Bob Watters was
charted with developing a document for the
registration of supporting evidence in Appendix
B.
There was a discussion regarding the numbering
structure use to label the CIPM and RMO
Key Comparisons. After some debate, it was
agreed that the numbering for all types
of comparisons (i.e., key, supplementary,
and pilot) should be consistent with the
database, but its final format need not
to be determine by consensus. Bob Watters
was asked to develop a numbering scheme
that is consistent with the database.
Bob Watters explained the format for results
of comparisons (see enclosures). Watters
emphasis that at this time it is more important
to submit the data to him in any format
than spending much time in satisfying the
proposed format.
Watters discussed some of the peculiar problems
that are resulting from the use of reference
values. In particular he alluded to some
examples in which the inclusion of additional
laboratories in the Key Comparison is leading
to misleading reference values.
8. Review of 1999 expenditures and 2000
budget
Steve
Carpenter reminded members of NMIs (NRC,
CENAM, NIST, and INMETRO) that they needed
to prepare end?of?year expenditure reports
for the OAS. Alan Robertson announced that
he had copies of NRC's report. Carpenter
requested that the report be rewritten using
the electronic format provided by the OAS.
Carpenter proceeded to read the proposed
SIM year 2000 budget (see enclosed document).
Carpenter announced that OAS had approved
$180k for year 2000 budget. He also explained
that the USA mission to the OAS may provide
additional funds later in the year.
As in 1999, the funds will be divided between
four NMIs (NRC, CENAM, NIST, and INMETRO)
who will see the distribution of the funds.
These countries are required to submit end?of?year
expenditure reports to the OAS.
9. Next meeting
Steve
Carpenter proposed that the next meeting
SIM-TC be held on July 2000 in Toronto,
Canada, as to coincide with the next NCSL
meeting. Léa Contier de Freitas suggested
that the meeting be held outside of the
USA. After some discussion, it was agreed
that the SIM Council in their next meeting
in Caracas, Venezuela would settle the matter.
10. Other Business
Alan
Robertson mentioned the submissions of SADCMET.
Pedro Espina reflected on his visit to the
South African NMI (CSIR-NML) as part of
an international peer review team, and spoke
highly of the South African efforts to maintain
and improve their metrology program.
The meeting was closed at 5:30 p.m.
