The CORESTA Routine Analytical Chemistry Sub-Group has been given the responsibility to provide a monitor test piece specific for ignition propensity testing, according to ISO 12863:2010.

A candidate CORESTA monitor test piece was manufactured in January 2014, with product specifications established on the basis of prototype cigarettes previously analysed. It was qualified as CORESTA Monitor Test Piece CM IP 2 in 2015, on the basis of a 2014 collaborative study and re-confirmed a year later (see CORESTA RAC Technical Report, 2014 Collaborative Study of CORESTA Ignition Propensity Monitor Test piece CM IP 2 for the Determination of Ignition Propensity and the corresponding 2015 Collaborative Study report, edited in March 2015 and April 2016 respectively).

The need to continue checking the stability of the CM IP 2 monitor test piece and using the results to support the laboratories proficiency and maintain their accreditation on the basis of a collaborative study of CM IP 2 and of NIST standard reference material 1082 for comparison purpose was agreed in April 2016. The goal of this report is to provide the statistical assessment of the results of this latest collaborative study.
