Описание (английский):

ISO 20774:2013 is applicable to the determination of carbon monoxide present in the sidestream smoke from cigarettes. The described method is specified using the ISO 3308 smoking parameters (puff volume, duration and frequency) and butt length, but it is technically compatible with other smoking regimes.

Overview

ISO 20774:2013 - Cigarettes: Determination of carbon monoxide in sidestream smoke specifies a reproducible laboratory method to measure carbon monoxide (CO) in sidestream smoke from cigarettes. The method uses a routine analytical linear smoking machine equipped with a fishtail chimney and is defined using the ISO 3308 smoking parameters (puff volume, duration and frequency) and butt length, while remaining technically compatible with other smoking regimes. The standard clarifies sampling, conditioning, smoking procedures, CO collection (off‑line bag and on‑line continuous systems) and calculation/reporting requirements.

Key technical topics and requirements

Scope and definitions: clear distinction between sidestream smoke (smoke emitted from the lit end) and mainstream smoke or environmental tobacco smoke (ETS).

Required apparatus: routine analytical linear smoking machine, fishtail chimney assembly, Cambridge filter pads or equivalent sidestream traps, and CO analyzers or calibrated gas mixtures.

Smoking parameters: method specified using ISO 3308 standard smoking conditions but compatible with alternative regimes if documented.

Sampling and preparation: guidance on selection of test portions, conditioning of cigarettes (atmosphere control per ISO 3402), butt marking and preparation.

CO measurement procedures: both off‑line (bag collection) and on‑line (continuous flow/data acquisition) calculation methods are included.

Calibration and reagents: use of standard gas mixtures and calibration procedures (including an alternative CO calibration annex).

Quality control: inclusion of monitor test pieces (e.g., CORESTA monitor) recommended to assess repeatability and reproducibility; statistical treatment of results and reporting formats.

Safety: note that hazardous materials and operations are involved and users must establish appropriate safety practices.

Practical applications

Comparative ranking of cigarette products based on sidestream CO yields.

Regulatory and compliance testing where sidestream CO data are required.

Product development and formulation changes to assess changes in sidestream emissions.

Quality control in manufacturing and third‑party tobacco testing laboratories.

Public health and exposure research investigating non‑user exposure to CO from tobacco products.
