Introduction: What is ASTM D638? ASTM D638 is the standard test method for measuring the tensile properties of plastics. Tensile tests are vital for evaluating the mechanical performance of plastic materials under stress, helping manufacturers and engineers ensure that their plastic products meet necessary safety and durability standards. This testing…
ASTM D638 is one of the most widely used international standards for testing the tensile properties of plastics. It provides detailed procedures to measure the tensile strength, yield strength, elongation, and modulus of elasticity of plastic materials. To comply with ASTM D638, a Universal Testing Machine (UTM) is required. This…
A Universal Testing Machine (UTM) is a versatile instrument used for determining the mechanical properties of materials under tension, compression, bending, and shear. Among the most widely adopted tensile testing standards for plastics and polymers are ASTM D638 and ISO 527. Both standards define the procedure for measuring tensile strength,…
