Measuring the rheological properties of polymeric materials at various temperatures and shear rates common to processing equipment. It covers measurement of melt viscosity, sensitivity, or stability of melt viscosity.
The Charpy and Izod methods are based on the same principle to test the Impact resistance of any material but still there are may difference between them.
Method to determine the dimensional changes and dimensional stability of textile floor coverings when they are exposed to certain heat and moisture conditions.
EN ISO 23999 specifies a method for determining the dimensional stability and curling behavior of resilient floor coverings (like vinyl, linoleum, rubber, etc.) after exposure to heat.
