Résumé

The ageing process is a common problem in refrigerated transport. This phenomenon has always been studied from the comparison of the K value of the in-service vehicles at nine or twelve years of use with the K value of their prototypes. This is a method that stems from the current regulation for the international transport of perishable foodstuff which allows certifying a new refrigerated vehicle produced in series on the basis of its prototype. The vehicle produced in a series may have a different K coefficient compared to its prototype due to reasons intrinsic to the production process or to discrepancies on the body itself. The estimation of this difference is necessary for the study of ageing. It is also an important issue for new refrigerated trucks certification. A previous paper highlighted the comparison of the K coefficient of fourteen newly manufactured semi-trailers and their prototypes. In this paper, the same experimental assessment is proposed for a representative number of refrigerated trucks. A comparison with previous results is also presented.
