ASTM D1623 : Standard Test Method for Tensile and Tensile Adhesion Properties of Rigid Cellular Plastics
Significance and Use
ASTM D1623-17 is a method for measuring the tensile strength and tensile adhesion property of rigid cellular plastics in specified test conditions. The standard is applicable to the mechanical performance and bonding characteristics determination of foams, including those of polyurethane, polystyrene, and phenolic types, and is used in construction, aerospace, automotive, insulation, and industrial packings. Tensile and adhesion testing play an important role in studying the structural stability, load-bearing capability, and bond integrity of foam-based materials and sandwich structures. The standard also supports material comparison, product development, quality verification, and bonded assembly evaluation. Presto offers advanced universal testing machines suitable for ASTM D1623 testing with precise load application, controlled crosshead movement, and software-based result analysis.
Scope
This standard covers the determination of tensile and tensile adhesion properties of rigid cellular materials tested under controlled temperature, humidity, and loading conditions. Different specimen configurations are used depending on foam thickness and testing requirements, including tensile testing of foam materials and adhesion testing between foam and substrate surfaces. Testing is generally performed using a constant-rate universal testing machine equipped with suitable grips and elongation measurement systems for accurate force and displacement analysis.
Notes
ASTM D1623 is widely used for evaluating tensile strength and adhesive bonding performance of rigid cellular plastics used in structural and insulation applications. Presto provides advanced tensile testing systems suitable for foam material and bonded assembly testing with accurate force measurement, stable gripping arrangements, and software-based reporting solutions for laboratory and industrial testing environments.
