ISO standard for determining migration of plasticizers

Recently NEN-EN-ISO 177:2017 was published specifying a method for the determination of the tendency of plasticizers to migrate from plastics in which they are contained into other materials or other plastics when they are brought into close contact.
This test is suitable a) for evaluating the tendency displayed by plastics, particularly in the form of films and sheets, to lose certain of their liquid constituents when they are brought into contact with materials that have an affinity for plasticizers, and b) for studying the tendency to migrate of plasticizers contained in a resin or a series of resins, in one or more concentrations (World Packaging Standardisation Newsletter, April 2017).
