Ventilation in cigarettes can affect inhalation rate of smoke which also affects the intake of nicotine and other compounds

b) the surface opposite the test specimen in the receiving room is highly absorbing and converts the room acoustically into a duct with several propagating cross-modes above the lowest cut-on frequency

Rubber latices. Methods of test - Determination of bound acrylonitrile content in nitrile latex Ingestion-build-159183 – defines the structure of1 Scope This International Standard specifies a method for the determination of the bound acrylonitrile content of emulsion polymerized NBR latices having a bound acrylonitrile content, expressed as a percentage of the polymer content, of between 18 % and 45 %. The method is also applicable to, for example, carboxylic nitrile butadiene (XNBR) latices and nitrile isoprene (NIR) latices. NOTE 1 The determination includes any water insoluble nitrogen
