ISO 11358 Thermogravimetric Analysis (TGA) of Polymers
The ISO 11358 standard specifies the procedure for performing thermogravimetric analysis (TGA), a technique used to study how the mass of a sample changes with temperature. This service is particularly valuable in metallurgy and material testing, especially when dealing with polymers, as it can provide insights into thermal stability, decomposition behavior, and phase transitions.
Thermogravimetric analysis involves heating a sample at a controlled rate while measuring the mass change over time. This method helps in understanding various aspects of polymer behavior under heat stress conditions, which are critical for quality assurance and development in metallurgy applications such as coatings, composites, and structural materials.
Polymers used in these sectors often undergo significant thermal degradation during processing or service life. By employing ISO 11358 TGA, we can determine the precise temperature at which weight loss occurs, thereby identifying critical process parameters and optimizing manufacturing techniques to enhance product performance.
The testing procedure involves precise sample preparation, typically involving a small, accurately weighed portion of the polymer sample. The sample is then subjected to a controlled heating rate in an inert atmosphere or under specific conditions relevant to the application domain. This ensures that any observed weight changes are due solely to thermal effects and not atmospheric interactions.
The results from this analysis can be used to establish critical processing temperatures, improve formulation of additives, and set standards for quality control. Additionally, TGA data provides valuable information on the thermal stability of materials, helping to predict their service life under various operating conditions. This is particularly important in sectors where temperature cycling is a factor.
The application of ISO 11358 TGA in metallurgy and material testing contributes significantly to ensuring that materials used in these industries meet strict quality standards and regulatory requirements. It allows for the optimization of production processes, reducing waste and improving efficiency. Moreover, it aids in the development of new materials with enhanced thermal stability and durability.

Scope and Methodology
The scope of this service includes the comprehensive evaluation of polymers using TGA according to ISO 11358-1:2010. The methodology involves precise sample preparation, loading into a TGA instrument, and conducting tests under controlled atmospheric conditions. We follow strict protocols to ensure that all variables are accounted for, providing reliable data on thermal stability.
The testing process begins with obtaining an accurate weight of the polymer sample. This is followed by placing the sample in a crucible or similar vessel suitable for TGA analysis. The crucible is then placed into the furnace of the TGA instrument, which heats the sample at a controlled rate. Throughout the heating process, mass changes are continuously monitored and recorded.
The results provide detailed insights into how the polymer responds to heat, including any decomposition or phase transitions that occur. This information can be used to refine manufacturing processes, optimize product design, and ensure compliance with industry standards. Our team works closely with clients to interpret these findings in the context of their specific applications.
We also provide detailed reports that include all relevant data points from the TGA analysis, along with recommendations for improving material performance based on our findings. These reports are tailored to meet the needs of quality managers, compliance officers, R&D engineers, and procurement professionals who require such information for decision-making purposes.
