Tests et valeurs-tests : application à l'étude de mastics utilisés dans la fabrication des vitraux

A numerical table concerns 56 stained glass windows in which different adhesive materials have been used for their joints.They have undergone an artificial ageing test under variable conditions. The collected data for each window make up 30 couples of successive values, which give the wind pressure and the deformation caused under the effect of the pressure. By representing the 56 average points in a two-dimensional plane "deformationpressure" we try to explain the dispersion of the average points. In this paper we examine if there is a relationship between the position of the average points in the plane and the conditions of the artificial ageing test. A further paper will deal with the scattering of the points around their 56 mean-points. Key-words : Monte Carlo test, Test-value. 28 Ph. D. ALEVIZOS, A. MORINEAU 1.
