NICr, - 12t)j-14th SEPTEMBER 197:1
A list of participants is attached (Appendix I).
Wednesday, 12th September
Joint Meeting of Tecbnology Group-and Smoke Study
Group.
It was proposed at the last meeting of the
Scientific
Commission that the Technology and Smoke Study
Groups should
study the questiou of tobacco damage by insects,
althou&4
the Agronomy and Phytopatbology.Groupg will be
mainly
concerned. A questionnaire will be circulated and
the
answers collated.
..Artho outlined the-programme of the Montreux
meeting-
(22nd--27th September,- 1914). Invitations should
-be expected
by October, and replies asked for by December
31st.

Thursday, lBth September
The Agenda is attached (Appendix 11).
1. Report on Cigar Sub-Group (van der Straeten)
The report (Appendix III) was accepted, and
Gottscho
will give a summary at the Tobacco Chemists'
Research_
Conference i-a October, 1973.
In answer to a question from Elmenhorst, van der
Straeten
confirmed that it was intended, after discussion
at the
Sciedtific Coftimiggion, to publish the
amoking.regime as a
.CORESTA-recomended method. The text would be
ready in
two months.
1-.1. Cigar Research Council.
Hiekson had sUggested that the C.R.C. should-
become an Associate of CORESTA. This was turned
down,
but it vas agreed that the C.R.C. could send
observers
to-ihe.Cigar Sub-Group: van der Straeten will pick
.-_,qp the contact with C.R.C.

3. Problems Related to Pesticides
Gaisch stated that he would Like to relinquish the
job of Chairman. Elmenhorst announced that Miss
Ayers
would be willing to stand as Chairman. It was
agreed
that the Sub-Group should elect their own Chairman
and,
if they wished to, a Secretary - i.e. the Smoke
Study Group
should not impose a new Chairman. C.I. Ayres made
it clear
that B-A.T. would welcome Gaisch conti-nuing.
as-Chair an-
and, whilst not definite, it is probable that he
will do so.
4. CORESTA Standard Methods
It was agreed that, in future, these would be
knorn
as CORESTA Recommended Methods.
4.1. Vapour Phase Components (SEITA)
Joigny proposed -that recoftended methods. thould
be
produced for carbon monoxide,.acrolein and H_QX
.(presumably so that*Gallia can be urged alongl).
Osddne opposed -(very stronglyl.), saying that-
HCN and
acroleii are not wholly.in-vapour phase, Al
o why choose
these partitulii~ three compound's out of. the-
"thou sands"
-hich are in the v1pa- phom. Hc point-od o-t-that,
in the U.S.A.,--standardisation was precluded
since
the Readers" bigost.would use'them anti-eigarette-
in
propaganda. Also,_each laborator-y-already has

A general "free -Zor-all" took place during which
a proposal by Lipp, that the SEITA proposal should
be
rejected, was turned down on a hand vote.
Elmenhorst proposed that a task force should be
set up not to produce recommended methods but to
accumulate inf ormation- on methodology and make a
report in 1974. On a hand vote, 15 were for the
proposal and 9 against.. - Complaints-were then
made
that some "observers" had voted and that many
delegates
kad failed to *express an opinion. The following
morning a written vote was taken: 24 were for the
proposal-, 16 against and 1 spoilt: paper (C. 1.
Ayres
voted for the proposal).
The task farce is:-
Joigny (SEITA)
Ayres (B-A.T., U.K.)
Kuhn (Austria Tabak)
Gaisch (F_T.R.)

It was agreed to finalise the position at
tho- ncxt mcotircg, but "romarks" on thc questl6u
should be sent in writing to Williamson.
4,3. Modifying Smoking Standards (141usemann)
HtLusermann proposed that the butt length used in
CORESTA methods should be changed to "tipping +
41mm",
as shown in Appendix VI.
Many people, including C.I. Ayres,.were caught
short by this one,.and were not clear how it
affected
their own brands.
After a lengthy discussion it was agreed that
(a) Members would send,Williamson, as quickly as
possible, details.-of.butt lengths used irk

5.2. Secretary's Nott by Mr. Hayn (1.6.73)
Regarding
Efficacy, of_ York I)qne in the Group Meetine
This was not circulated but, from Elmenborst's
comments, appeared to reflect the criticisms
voiced at
the last meeting o-f the Scientific Commission
that
"Many members contribute nothing to the meeting.
Bome companiet ehtige their dolegat-es too
frequently. There is a threat of an invasion
by "commercial" rather than "scientific"
delegates.
Not enough delegates are willing to take part in
the collaborative experimental work."
Hayn had apparently suggested that any delegates
who have not Shown active interest for two years
should
be deleted from the mailing list.
It'was'agreed that the- Chairman and Secretary,
together with the S.C. members, should consider
whether.
they are happy with the Smoke Study Group and,-if
necessary, tpake recommendations at -the next
meeting.
