Resistance of Barrier Materials Against Toxic Compounds Permeation and Its Evaluation in Accordance with New European Norms

Study of barrier material resistance against permeation of toxic compounds belongs to a category of chemical warfare agents and toxic industrial chemicals are permanently insufficiently solved problems. This work deals with changes in approaches to testing barrier materials against toxic compounds permeation in static and dynamic conditions. An aim of this information is to describe specifications of cancelled norms of ČSN EN ISO 6529 (2002) a ČSN EN 374-3 (2004) with newly established norms ČSN EN 16523-1 a 16523-2 (2015). Authors focused on specification and comments of changes in such parts of norms concerning their scope, terms and definitions. A selected problem was solved with the help of analyse of newly established norms in a form of comments. Conditions for specification of understanding of mentioned problems in a context of established or occasionally prepared methods of testing resistance barrier materials against toxic compounds permeation have been formed with elaborated research.
