JUDGMENT OF FLOORS BEEN CONSIDERED TO BE INFERIOR BY FOOT TOUCHING

Evaluation method of deformation properties of floors from a viewpoint of comfortableness (Part 1)

Abstract

Recently, there were some floors which were good by previous evaluation method but which were considered to be low. Reason of low was investigated. Sensory scale about deformation of floors was made by sensory tests. But correlation between this scale and the previous physical values of floors was not enough. Factor of bad correlation was estimated as some kind of softness during foot touching. Then provisional method to measure the softness was developed. Another physical values with this method were effective to improvement of bad correlation. As a result, the reason of inferior was detected.
