TEST OF PERMEABILITY TO WATER OF PACKAGING
Plastics let the gas diffuse through themselves. This characteristic is essential to choose packaging or building insulation materials and to ensure the protection of a product. Sercovam’s qualified team carries out permeability and characterization materials tests to evaluate the diffusion level through packaging as films, sheets or containers according to ISO 2528: Sheet materials - Determination of water vapour transmission rate – Dish Method and : Standard test methods for water vapour transmission of materials or for the validation tests by the U.S. Pharmacopeia USP Chapter 671 of the containers of pharmaceutical products. The principle of these methods can also be applied to sealing materials such as adhesives, under-roof screens or other building products according to NF EN ISO 12572 (under development in our laboratories): Hygrothermal performance of materials and products for buildings - Determination of transmission properties of water vapor. With these , the transmission coefficient of water vapor in g/m2.24h can be determined.
