ISO/TC 126/SC 1 - Physical and dimensional tests

This document specifies a method for the determination of the width of strands of cut tobacco. This method is only applicable on samples of strands of cut tobacco with a uniform cut width. NOTE There are other ways of measuring the width of the strands of cut tobacco. A system with the same accuracy can be used, for example a microscope with an internal fitted ruler or a camera with image processing system.

This document specifies a method for the determination of air permeability (AP). It is applicable to materials used as cigarette papers, filter plug wrap and filter joining paper, including materials having an oriented permeable zone or discrete permeable zones where the measured permeability is in excess of 10 cm3·(min−1·cm−2) at 1 kPa. In addition, it is applicable to banded cigarette papers, with bands of a width of at least 4 mm. NOTE For an estimate of the air permeability of materials outside the scope of this document, see Note 3 in 5.1.2 and 7.6.1.4.

This document specifies a method for the determination of ventilation which is applicable to cigarettes.

This document specifies additional test methods for routine analytical cigarette-smoking machines intended to check the conformity of these machines with ISO 3308 and ISO 20778. It only establishes additional test methods for smoking machines and does not deal with actual smoking, which is described in other International Standards. It is composed of four sections relating to — the determination of pressure drop (Clause 4); — the determination of significant puff profile parameters (Clause 5); — the verification of restricted smoking (Clause 6); — the description of the soap film bubble flowmeter for the determination of the puff volume (Clause 7). NOTE There are more possibilities for determining the aforementioned parameters. Systems giving the same results and accuracies can be used. The certificate of conformity with this standard can be obtained from the machine manufacturer.

ISO 6565:2015 describes a method for the measurement of the draw resistance of cigarettes and pressure drop of filter rods, and specifies the standard conditions applicable to such measurements. It is applicable to cigarettes, filter rods, and, by extension, to cylindrical tobacco products similar to cigarettes.

ISO/TS 3550-3:2015 specifies a method for the determination of loss of tobacco from cigarette ends using a vibro-bench. This method applies to the determination of loss of tobacco from cigarette ends in manufacturing site, throughout the distribution network and also while in the smoker's pocket. NOTE Two other methods for the determination of loss of tobacco from the ends, using a rotating cylindrical cage and a cubic rotating box (sismelatophore), are described in ISO 3550‑1 and ISO 3550‑2, respectively.

ISO 2971:2013 specifies a non contact, optical method of gauging for determination of the mean, minimum and maximum diameters and the ovality (or roundness) of rod-shaped objects with a nominally circular or oval cross section that is convex curvilinear. The method is applicable, in particular, to cigarettes and filter rods.

ISO/TS 7821:2005 provides a practical framework for the operations of dividing a lot (not necessarily homogeneous) of tobacco or tobacco products into several similar samples intended for collaborative studies, either within or between laboratories.

ISO 7210:2013 specifies additional test methods for routine analytical cigarette-smoking machines intended to check the conformity of these machines with Clause 4 of ISO 3308.

ISO 20193:2012 specifies a method for the determination of the width of strands of cut tobacco. It is only applicable if there is a uniform cut width.

ISO 6565:2011 describes a method for the measurement of the draw resistance of cigarettes and pressure drop of filter rods, and specifies the standard conditions applicable to such measurements. ISO 6565:2011 is applicable to cigarettes, filter rods and, by extension, to cylindrical tobacco products similar to cigarettes.

ISO 2965:2009 specifies a method for the determination of air permeability (AP). It is applicable to materials used as cigarette papers, filter plug wrap and filter joining paper, including materials having an oriented permeable zone or discrete permeable zones where the measured permeability is in excess of 10 cm3 . (min-1 . cm-2) at 1 kPa. In addition, it is applicable to banded cigarette papers, with bands no narrower than 4 mm.

This International Standard specifies a method for the determination of ventilation which is applicable to cigarettes.

This International Standard describes a method for the measurement of the draw resistance of cigarettes and pressure drop of filter rods, and specifies the standard conditions applicable to such measurements. It is applicable to cigarettes, filter rods and, by extension, to cylindrical tobacco products similar to cigarettes.

Contains additional test methods for routine analytical cigarette-smoking machines. Intended to check the conformity of these machines with ISO 3308. Replaces the first edition.

The principle of the method is drawing air in the standard smoking direction through an unlit cigarette at a constant flow, measuring the amount leaving the mouth end, partitioning and measuring separately the individual components of ventilation by the apparatus, calculating the degrees of ventilation. Applies in particular to the testing of cigarettes during manufacture.

Provides a practical framework for operations of dividing a lot (not necessarily homogeneous) of tobacco or tobacco products into several similar samples intended for collaborative studies either within or between laboratories. Covers tobacco as a test medium in the forms of powder, cut tobacco, cigarettes, and leaves or strips.
