ASTM D751

ASTM D751 is a standardized test method used to measure the flexibility and pliability of rubber and plastics at various temperatures. It involves applying a small, standardized force to a specimen and gradually cooling it until it breaks or loses its flexibility. This helps determine how well the material can withstand bending and stretching in different environments, ensuring suitability for specific applications like seals, hoses, or durable goods. The test provides valuable data on a material's performance under conditions of temperature variation, aiding manufacturers in quality control and product development.
