Plastics - Liquid epoxy resins - Determination of tendency to crystallize (ISO 4895:2014)

This International Standard specifies a method for determining the tendency of liquid epoxy resins to crystallize. The tendency to crystallize is determined by observing, at specified time intervals, changes in fluidity and the onset of crystallization.

Kunststoffe - Flüssige Epoxidharze - Bestimmung der Kristallisationsneigung (ISO 4895:2014)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Kristallisationsneigung flüssiger Epoxidharze fest. Die Kristallisationsneigung wird bestimmt, indem Änderungen in der Fluidität und der Beginn der Kristallisation in bestimmten Zeitintervallen beobachtet werden.

Plastiques - Résines époxydes liquides - Détermination de la tendance à la cristallisation (ISO 4895:2014)

L'ISO 4895:2014 spécifie une méthode de détermination de la tendance à la cristallisation des résines époxy liquides. Cette tendance à cristalliser se détermine par observation, à intervalles de temps donnés, des variations de la fluidité et d'apparition de la cristallisation.

Polimerni materiali - Tekoče epoksidne smole - Ugotavljanje nagnjenosti h kristalizaciji (ISO 4895:2014)

Ta mednarodni standard določa postopek ugotavljanja nagnjenosti tekočih epoksidnih smol h kristalizaciji. Nagnjenost h kristalizaciji se določi z opazovanjem sprememb v fluidnosti in opazovanjem nastanka kristalizacije v določenih časovnih intervalih.
