Foreword
Introduction
1 Scope
2 Statistical functions for repeatability (r),
reproducibility (R) of yield measurements and
compliance tolerances for declared smoke constituent
yields
2.1 Statistical functions for repeatability (r) and
reproducibility (R)
2.2 A statistical model for compliance tolerances
3 Sources of data
3.1 International collaborative studies
3.2 UK Department of Health Cigarette Survey data
4 Comparison of 2003 CORESTA Collaborative Study data with
those previously reported
4.1 General
4.2 Comparison of repeatability r[20] values from CCS-03
with other collaborative studies
4.3 Comparison of reproducibility R[20] values from CCS-03
with other collaborative studies
4.3.1 General
4.3.2 Relationship between reproducibility R[20] and
smoke constituent yield
4.4 Comparison of R[100] reproducibility values from
collaborative studies with measurement tolerances
estimated from the UK Department of Health Cigarette
Survey data
5 Review of information relevant to setting a compliance
tolerance for carbon monoxide
5.1 General
5.2 Compliance data for current tolerances
5.3 Confidence intervals associated with yield measurements
5.4 Statistical models
5.5 Prediction of a tolerance for CO from the relative
variability in their reproducibility values
6 Conclusions
