Migration modelling means a calculation of the specific migration level of a substance based on the residual content of the substance in the material or article applying generally recognised diffusion models. These are based on scientific evidence overestimating real migration and taking into account the Guidance document on migration modelling.

Examples of Migration modelling in a sentence

  • Definitions: Migration modelling is now well established for many mono-layer plastics.

  • Definitions: Migration modelling is based on estimating the diffusion coefficient of a migrant in the polymer, DP by using the PIRINGER equation [DP = f(AP, Mw, T)] AP is a polymer-specific constant, Mw is the migrant molecular weight and T is temperature.

  • Migration modelling is based on two major factors: (i) the kinetic factor is the diffusion constant of a migrant in the plastic(s) whose diffusion is considered to be the rate limiting step, and (ii) the thermodynamic factor is the partition coefficient of a migrant between the food contact plastic and the food simulant KP/F.

  • Leak-detection system means a system capable of detecting the failure of either the primary or secondary containment structure or the presence of a release of hazardous waste or accumulated liquid in the secondary containment structure. Such a system must employ operational controls (e.g., daily visual inspections for releases into the secondary containment system of aboveground tanks) or consist of an interstitial monitoring device designed to detect continuously and automatically the failure of the primary or secondary containment structure or the presence of a release of hazardous waste into the secondary containment structure.
