Sub-Group Cigar Smoking Methods

Coordinator: Bob Van Mierlo

Scandinavian Tobacco Group Eersel BV, The Netherlands

Secretary: Marcel Crijnen

Dutch Cigar Manufacturers Association, The Netherlands

Liaison SC: Michael Meger, JTI

Objectives:

1- To develop and update CORESTA Recommended Methods as requested by the Scientific

Commission by investigating the technical problems associated with the mechanical smoking of cigars

2- To conduct periodical collaborative studies in order to improve repeatability and reproducibility in

different cigar sizes and types

3- To establish confidence intervals for the smoke yields of all different cigar sizes

3CSM SG Report



❖ Last Meeting: 20 April 2018, Cava de’ Tirreni, IT (MST)

❖ Summary of the activities and discussion:

➢ Periodical collaborative studies to improve r&R: the results of the 13th

study were discussed with the group.

➢ Potential parameters that could influence r&R have been discussed:⚫ Setup and results of CS13.

⚫ Setup of future work based on learnings CS13.

⚫ Options to reduce r&R.

⚫ Reference cigars.

➢ Next collaborative study setup.

➢ Other cigar related activities.





❖ Products used in the 13th CS: B, D, G, H, I





❖ Products used in the 13th CS



For all the products 5 replicates

of 8 cigars have been smoked.

Other smoking parameters:

Puff Frequency : 40 s

Puff Duration : 1.5 s

Butt Length: 33 mm

6CSM SG Report



❖ The 11 participants in the 13th CS:



- Nice participation level (only 7

labs in 12th study)!

- Many product issues reported

linked to product D (due to

shipment?).

- Therefore, Product D result were

excluded out of the study.

❖ Study setup:



11 participating laboratories

5 products assessed

7 parameters analyzed

385 datasets expected:

→ 364 datasets were

completed (95%)

8CSM SG Report



❖ Focus points in the study protocol, in line with the 12th study:

➢ Continued focus on conditioning of product prior to smoking, to ensure

that they are conditioned in line with the CRM’s.

➢ Continued focus on diameter determination to minimize impact on holder

constructions and puff volumes.

➢ Central distribution of samples to avoid differences in sub-samples.





❖ Comments:

➢ The individual results have been expressed in mg/cigar and in mg/g. For practical considerations, only the results in mg/cigar have been used in the statistical study.

➢ Outliers:

r&R product B – trend over time




r&R product G – trend over time




Relative repeatability r % from CS 1-13




Relative reproducibility R % from CS 1-13

❖ Overall conclusions 13th CS:

➢ Product B: Mean, repeatability and reproducibility estimations in line with previous studies.

➢ Product G: Mean, repeatability and reproducibility estimations in line with previous studies.

➢ Products H and I: Both new products provide levels of mean, repeatability and

reproducibility in line with the expectations, and other products.

➢ The 4 products characterized by the current collaborative study provide yields of nicotine,

NFDPM and CO located in the lower part of the measurement ranges. Further attentions

should be taken to build the 14th CS in accordance with the expected measurement

ranges.

➢ The changes made in the 11th CS and continued in the 12th and 13th CS have a positive

impact on the repeatability and reproducibility estimations.

➢ Learnings product D have to be taken into account in the next CS.

❖ Future activities:

➢ In the 14th Collaborative Study, we intent to include some reference products.

⚫ B: cigarillo, non-ventilated (STG)

⚫ G: CM8

⚫ C or a larger reference cigar (Swisher or STG)

⚫ H: cigarillo, ventilated (similar products as product B)

⚫ J: a tipped cigar (Altria?)

The timing of the study will depend on the availability of the reference products.

➢ Alignment on reference products.

➢ Next SG meeting: Q2-3 2019 (depending on timing CS).





Other cigar related activities

❖ NWIP #121:

Review of CRM64 & CRM65 to make them more suitable and robust from a

standardization point of view, and to allow other technical solutions to be used as

well in the methods, which result in a similar functional output.

⚫ Updated CRM64 and CRM46 available on the Coresta website.

⚫ Collaborative study performed – report pending (relevant for update CRM65).

⚫ Work started to update CRM66 and CRM67 as well.




NWIP 148: Long filler project




❖ NWIP #148:

⚫ Project objective: Identify and resolve technical limitations and challenges

within smoke collection of handmade long filler cigars. Technical report /

guidance which in combination with CRM 64 and 65 can enable the smoking of

handmade cigars

Sealing

Cutting

Lighting/relighting

Smoke trap capacity

Solutions / guidance have been identified for the above. Significant variation within and

between labs have been experienced.

⚫ Collaborative study early 2019; candidates to participate are welcomed

⚫ Final report medium 2019
