EN ISO 11357-7 Plastics - Differential Scanning Calorimetry (DSC) - Determination of Crystallization Kinetics

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 11357-7 testing. This standard specifies two methods (isothermal and non-isothermal) to study the crystallization kinetics of partially crystalline polymers using differential scanning calorimetry (DSC).

Differential scanning calorimetry (DSC) is a widely used thermal analysis technique to study the thermal behavior of materials, including plastics. In the context of Chapter 7, the focus is on examining the crystallization process of plastics and determining the crystallization kinetics.

Crystallization of plastics is a process in which the polymer chains in the material align themselves in an orderly fashion to form a crystalline structure. This process is essential in determining the material's properties such as mechanical strength, optical clarity, and thermal stability.

EN ISO 11357-7 provides guidelines and procedures for conducting DSC measurements to analyze the crystallization kinetics of plastics.

The standard typically includes details about:

• Sample preparation: The standard may specify requirements for the preparation of plastic samples, such as size, shape, and fit prior to analysis.
• DSC measurements: Outlines the DSC analysis conditions used during the measurement, including heating and cooling rates, temperature range, and atmosphere (usually nitrogen).
• Data analysis: The standard can describe methods of interpreting DSC data to determine crystallization temperature, crystallization enthalpy, and crystallization kinetics.
• Reporting: The standard may also contain guidelines for reporting results from DSC analysis.

By following the procedures outlined in EN ISO 11357-7, researchers and manufacturers can gain valuable insight into the crystallization behavior of plastics that can help optimize processing conditions and understand the performance characteristics of the material.
