A matter of concern on durability for users is not durability of individual material but of performance of building elements. As tests using building elements however require large-scale work, therefore small-scale ones are desirable and practicable for estimating durability. The frame for estimating durability in performance, which has hierarchy from building elements to materials, was proposed. The case studies on estimation procedures were carried out for some actual building elements, and it was made clear that durability tests are able to do at various levels. The possibility of durability estimation by a lower-level test depends on an item of performance, the construction of a building element, and particularly the existence of a reasonable method to convert the levels.
