ASTM D618-21 is the current standard practice for conditioning plastics for testing, establishing uniform temperature and humidity protocols to ensure reliable data comparison across laboratories. Purpose and Significance
If “D61821” was a typo for another standard (like D618 for conditioning plastics, or D1821 for something else), let me know and I can help correct the number. astm d61821 pdf
ASTM D618-21 vs. ISO 291: While both address plastic conditioning, ISO 291 is more limited, describing only two standard temperature and humidity combinations. ASTM D618-21 is the current standard practice for
This standard is widely applied in quality control, material selection, and failure analysis for thermoplastics, thermosets, elastomers, and composites. Compliance with D6182-21 helps ensure that DMA data are comparable and reliable for engineering design or specification purposes. ASTM D6182-21 standard : The official ASTM standard
ASTM D6182-21 is a standard test method developed by ASTM International (formerly known as the American Society for Testing and Materials). The test method is titled "Standard Test Method for Determining the Extractable Content of Plastic Materials."
