Abstract

Procedimiento para determinar magnitudes reológicas características de materiales viscosos, especialmente caucho y mezclas de caucho, comprimiendo una muestra cilíndrica previamente calentada a una temperatura determinada por los lados frontales para la medición de la viscosidad por una fuerza a una altura de muestra previamente dada, para, a continuación, después de descargar a través del mismo tiempo indicar por la altura de dilatación una medida para la elasticidad, caracterizado porque como mínimo dos muestras de igual forma de la misma carga se cargan y descargan con fuerzas arbitrarias, distintas entre sí, que conducen a tiempos de ensayo entre 5-150 segundos, midiéndose durante la carga y descarga en cada caso un tiempo a través de una sección de recorrido con una deformación de la muestra a menos de un 60 % de la altura original.
