ISO 11358 Thermogravimetry of Polymers

ISO 11358 is an international standard that outlines the thermogravimetry method for analyzing the thermal behavior of polymers. This technique involves subjecting a polymer sample to controlled temperature changes and measuring its weight changes as it undergoes thermal decomposition.

    Introduction to ISO 11358

    ISO 11358 provides a standardized approach to perform thermogravimetric analysis (TGA) on polymers. TGA is widely used to characterize polymers’ thermal properties and behavior, making it essential for research, polymer’s thermal stability, decomposition kinetics, compositional analysis, quality control, and understanding the performance of polymer materials. Thermogravimetry of polymers is crucial in various applications, including material selection, processing optimization, and assessing the polymer’s suitability for specific end-use environments.

    ISO 11358 Test Method

    The ISO 11358 test method involves heating a polymer sample at a controlled rate and continuously monitoring its weight change as a function of temperature. The test is conducted in the following steps:

    Test setupThe polymer specimen is placed in the TGA equipment, and the analysis chamber is purged with an inert gas to eliminate any atmospheric effects. The TGA equipment gradually increases the temperature at a controlled rate, and the specimen’s weight change is continuously recorded.  As the temperature rises, the polymer undergoes thermal decomposition, resulting in weight loss.
    RecordingThe thermal decomposition data is analyzed to record the weight loss or gain, providing valuable data on the polymer’s degradation, thermal stability, and compositional analysis.

    ISO 11358 Specimens

    Specimen detailsISO 11358 specimens are representative of the polymer being analyzed.
    Specimen dimensionsISO 11358 does not specify a standard specimen size, as it varies based on the type of polymer and the TGA equipment used.
    Specimen preparationBefore testing, the polymer specimen is carefully prepared to ensure uniformity and eliminate any external contaminants.

    ISO 11358 Results

    The TGA data provides valuable insights into the polymer’s thermal stability and degradation behavior. Weight loss peaks in the thermogram correspond to specific decomposition events, allowing researchers to identify the polymer’s thermal transitions and compositional changes. This standardized method plays a significant role in polymer research, material characterization, and quality control, contributing to the advancement of polymer science and various industrial applications.

    Standards Related to ISO 11358

    ISO 11357 – Differential Scanning Calorimetry (DSC) of Polymers and ISO 6721 – Thermoplastic Materials – Determination of Dynamic Mechanical Properties are the related standards.
