ASTM D2731 is the ASTM standard titled Standard Test Method for Elastic Properties of Elastomeric Yarns (CRE Type Tensile Testing Machines). It describes a test method for evaluating how elastomeric yarns respond under controlled tensile loading, helping users assess elastic performance in a consistent way. This matters for quality control, product comparison, and technical specification work where dependable tensile behavior is important.

ASTM D2731 standard overview

This standard provides a defined test method focused on the elastic properties of elastomeric yarns when measured with CRE type tensile testing machines. In practical terms, it supports repeatable evaluation of how these yarns behave during stretching and recovery-related testing. ASTM D2731 is used as a technical reference for laboratories and manufacturers that need a common approach to generate comparable results and support material assessment.

Where is ASTM D2731 used?

ASTM D2731 is commonly used in testing environments that evaluate elastomeric yarns for product development, incoming inspection, and production quality control. It is relevant wherever CRE type tensile testing machines are used to measure elastic behavior in yarn materials. The standard is especially useful when organizations need a consistent method for comparing test results across batches, suppliers, or internal specifications.

Practical importance of ASTM D2731

Using ASTM D2731 helps reduce variation in test practice and improves confidence in reported elastic property data. For procurement and compliance teams, it provides a recognized technical basis for material evaluation. For laboratories, it supports consistency in tensile testing workflows and helps align results with customer or internal requirements. ASTM D2731 is therefore valuable when reliable, repeatable yarn testing is needed for decision-making.
