Refractory products — Determination of refractoriness-under-load (differential - with rising temperature)

Produits réfractaires — Détermination de l'affaissement sous charge (différentiel - avec élévation de la température)

Abstract / scope

Specifies a method for determining the deformation of a refractory product subjected to a constant load under conditions of progressively rising temperature, or "refractoriness under load" - differential method, with rising temperature. The test may be carried out up to maximum temperature of 1700 C.
