Astm d297什麼意思
ASTM D297 is a standard test method established by the American Society for Testing and Materials (ASTM) for the "Measurement of Compressive Properties of Rigid Plastics". This standard outlines the procedures for determining the compressive properties of rigid plastics, including the yield strength, ultimate compressive strength, and Young's modulus under compressive loading.
The test method involves applying a compressive force to a test specimen of the plastic material until it fails, and then analyzing the stress-strain data to determine the material's compressive properties. This information is useful in the design of products made from rigid plastics, such as automotive parts, structural components, and consumer goods, where the material's ability to withstand compressive forces is an important consideration.
