What is ISO 9512 on Determination of ventilation in cigarettes about?
ISO 9512 is an international standard that covers definitions and measurement principles for the determination of ventilation in cigarettes which enables you to alter tobacco combustion and reduce toxicity to reduce the harmful effects on users.
ISO 9512 specifies principle in which air is drawn, at a constant flow rate, in the standard smoking direction through an unlit cigarette. The individual components of ventilation are measured separately. The degrees of ventilation are obtained by calculation.
Who is ISO 9512 on Determination of ventilation in cigarettes for?
ISO 9512 on determination of ventilation in cigarettes is applicable to:
- Manufacturers of cigarettes
- Dealers and importers of cigarettes
- Testing houses and labs for cigarettes
Why should you use ISO 9512 on Determination of ventilation in cigarettes?
Ventilation in cigarettes can affect inhalation rate of smoke which also affects the intake of nicotine and other compounds. Smoke may become available to lung cells prone to adenocarcinomas as a result of altered puffing and inhalation. Filter ventilation appears to have played a role in the rise in lung adenocarcinomas among smokers, according to recent findings.
ISO 9512 provides you guidance on principle, standard conditions, requirements for apparatus, sampling, checking of apparatus, procedure, expression of results, precision and test report allows you to limit the toxicity and addiction in cigarettes.
Guidance in ISO 9512 enables you to determine the ventilation in cigarettes which enables you to determine the aldehyde yields and reduce smoking related morbidity and mortality in cigarettes.
What’s changed since the last update?
BS ISO 9512:2019 supersedes BS ISO 9512:2002, which is now withdrawn.
Changes in BS ISO 9512:2019 include -
- Introduction of the prime designator (Q′) to indicate a component of the ventilation flow that is measured on the inlet side to the cigarette or standard and that is converted to a volumetric flow at the outlet side (see 3.5)
- Addition of a typical calibration process for ventilation standards (see A.3.2 j)
- Updated product repeatability and reproducibility statistics (see Clause 11)
- Editorial changes in accordance with current guidelines
