Medical Laboratory Testing: Tensile Properties
Tensile Properties testing at -40 to 120°C measures how materials respond to pulling forces across a wide temperature range. The test pulls a specimen at a constant rate while recording strength, modulus, and elongation at different temperatures up to 20,000 lbs load capacity. For medical manufacturers, temperature-dependent tensile data ensures plastics, elastomers, films, and components maintain mechanical performance during cold storage, hot sterilization, and clinical use.
Materials can become brittle at low temperatures or soften at high temperatures, affecting device reliability. Applus+ Reliable Analysis already maintains accredited tensile testing with environmental chambers capable of -40 to 120°C and high load capacity, integrated with our polymer characterization and thermal analysis programs.
These evaluations support material qualification and design validation for medical tubing, films, housings, and flexible components. Manufacturers use temperature-dependent tensile data to select robust materials and demonstrate performance across expected environmental conditions. Applus+ Reliable Analysis delivers accurate, reproducible results using equipment already operating daily under our ISO/IEC 17025 accreditation.
Common Tensile Properties Medical Testing Standards
ASTM D638 Tensile Properties of Plastics
ASTM D638 determines the tensile properties of plastics by pulling a standard dumbbell-shaped specimen at a constant rate until failure while measuring stress and strain. When performed at temperatures from -40 to 120°C, it evaluates how properties change with temperature. It is widely used for medical plastics in tubing, housings, and components to ensure mechanical performance across the full range of storage, shipping, and use temperatures.
ISO 527-1 Plastics General Principles
ISO 527-1 outlines general principles for tensile testing of plastics, including testing at non-ambient temperatures. The standard specifies specimen preparation, test speed, and calculation of strength, modulus, and elongation. It is essential for medical polymers to verify tensile behavior at cold and elevated temperatures for European MDR compliance and to ensure reliability in varying environmental conditions.
ASTM D412 Vulcanized Rubber and Thermoplastic Elastomers
ASTM D412 measures the tensile properties of vulcanized rubber and thermoplastic elastomers using dumbbell or straight specimens pulled at a constant rate. When performed at temperatures from -40 to 120°C, it evaluates changes in tensile strength, elongation, and modulus. It is widely used for medical seals, gaskets, tubing, and flexible components to ensure elasticity and strength are maintained across temperature extremes.
ASTM D882 Tensile Properties of Thin Plastic Sheeting
ASTM D882 determines the tensile properties of thin plastic sheeting and films by pulling rectangular specimens at a constant rate. When conducted at temperatures from -40 to 120°C, it assesses how films behave under thermal variation. It is particularly valuable for medical packaging films, sterile barriers, and flexible drapes to ensure they retain mechanical integrity across the expected temperature range.
