Product Technology

The Product Technology Study Group is concerned with the characterization of tobacco, tobacco products, including cigarettes, cigars, oral tobacco products, e-vapour and heated tobacco products, and their components, in terms of physical and chemical properties. This includes the development and maintenance of physical and chemical test methods and reference products.
