ASTM D5630 is a standard test method used to determine the quantity of volatile and semi-volatile components, including plastic content, in compounded plastic materials via thermogravimetric analysis (TGA). This method is essential for quality control and material verification, ensuring that plastics and composite materials meet specified compositions for manufacturing processes and end-use applications. During the test, a sample of the plastic material is heated to a predetermined temperature that causes the volatile components to evaporate, and these losses are measured as a percentage of the total weight. This provides an accurate assessment of the material’s composition, particularly the content of fillers, plasticizers, and other additives that can influence the physical properties and performance of the final product. ASTM D5630 is widely used in industries such as automotive, aerospace, and electronics, where precise material specifications are critical for product reliability and safety.
