Building materials and components in the vertical position: Exposure to accelerated climatic strains (NT BUILD 495)


  • This NORDTEST method is intended for exposing materials and components used in the building envelope to UV light, heat, water and frost. The method seeks to simulate the natural climatic strains. Its objective is to concentrate the individual climatic factors so that, in total, they produce a cycle of strains giving degradation results similar to natural exposure but in a much shorter period of time.


Nordtest is a trademark of Nordic cooperation in conformity assessment. The emphasis of Nordtest is to develop, promote and innovate Nordic test methods and pre-normative activity. Nordtest endeavours to remove technical barriers to trade and promotes the concept: “Approved once, accepted everywhere”.
