BS ISO 7210:2013 pdf free.Routine analytical cigarette-smoking machine
BS ISO 7210 specifies additional test methods for routine analytical cigarette-smoking machines intended to check the conformity of these machines with ISO 3308:2012, Clause 4.
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 three sections relating to:
一the determination of pressure drop (Clause 4);
一the determination of significant puff profile parameters (Clause 5);
一the verification of restricted smoking (Clause 6).
NOTE There are more possibilities to determine the aforementioned parameters. Systems giving the same results and accuracies can be used. The certificate of compliance with this International Standard may be obtained from machine manufacturer. The frequency to carry out these additional test methods for smoking machines’ verification is not part of the scope of this International Standard.
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 3308:2012, Routine analytical cigarette-smoking machine – – Definitions and standard conditions
ISO 3402, Tobacco and tobacco products一Atmosphere for conditioning and testing
For the purposes of this International Standard, the following terms and definitions apply.
static pressure difference between the two ends of a pneumatic circuit (of a smoking machine) when it is traversed by an air flow under steady conditions in which the measured volumetric flow, under standard conditions, at the output end is 17,5 ml/s.
interval of time during which the port of a smoking machine is connected to the suction mechanism
volume leaving the butt end of a cigarette and passing through the smoke trap of a smoking machine
all smoke which leaves the butt end of the cigarette during the interval of time between successive puffs
aperture of the suction mechanism through which a puff is drawn and to which is attached a smoke trap
element of a smoking machine consisting of one or more cigarette holders, one trap and a means of drawing a puff through the trap
Measurement, under well-specifed air flow conditions, of the pressure drop of a smoking machine by means of an appropriate manometer.BS ISO 7210 pdf download.
