ISO 11357-3 Plastics - Differential Scanning Calorimetry (DSC) - Part 3: Determination of Melting and Crystallization Temperature and Enthalpy

This part of the ISO 6272 standard, developed by the International Standards Organization (ISO), specifies a method for determining the melting and crystallization temperatures and enthalpies of crystalline or partially crystalline plastics.

Use of this part of ISO 11357 may involve hazardous materials, processes or equipment. This part of ISO 11357 does not claim to address all the security problems associated with its use. It is important for the user of this part of ISO 11357 to establish appropriate health and safety practices and to determine the applicability of regulatory restrictions prior to use.

Measurements are made using the differential scanning calorimetry method, which consists of determining the amount of heat transferred or captured from a given sample in a unit of time required to maintain the same temperature of the sample and a neutral thermal reference (empty crucible) during heating.

The proportionality of the measurement signal to the thermal flux occurring in the DSC allows the thermal capacitance to be directly measured and the cp(T) relationship to be determined, thereby quantitatively "observing" the transformation of the sample material based on the shape.

The thermal flux value (dH/dt) depends, first of all, on the type of conversion or thermal reaction occurring in the sample, as well as on instrumental measurement factors.

Among the services provided by our organization within the framework of material testing services, there are also ISO 11357-3 standard tests.
