Wire ties were pulled until fracture. Table and force-extension curves show how test speed affects peak load and maximum elongation. As the speed was doubled from 2 to 4 inches per minute, the maximum elongation was reduced by almost half. As the speed...
The tear strength of thermoset rubbers, thermoplastic elastomers, and silicones can be measured according to specification ASTM D624. The test measures the strength required to initiate a tear in a material. D624 describes multiple differen...
Spinal Implants are tested according to several ASTM standards. ASTM F1717 is intended to provide a basis for the mechanical comparison among past, present and future spinal implant assemblies. Three static and one fatigue mechanical test of...
Typical points of interest when tensile testing a material include: ultimate tensile strength or peak stress; modulus of elasticity, offset yield strength, which represents a point just beyond the onset of permanent deformation; and elongation at ...
One of the most common specifications that our customers follow is ASTM D882 which is the Standard Test Method for Tensile Properties of Thin Plastic Sheeting. This test is very similar to the common ASTM D638 test whereby plastic material is pulled u...
ASTM D1414 (D 1414) covers multiple properties of O-Rings. Part of the specification includes tension testing for determining the breaking force, tensile strength, and ultimate elongation of an o-ring. The tension test is intended to be performed on ...
A suture is a medical device that doctors use to hold skin, internal organs, blood vessels and all other tissues of the human body together, after they have been severed by injury or surgery. They must be strong enough to hold the tissue and flexible e...
ASTM F88-94 Package Peel Tensile Strength is summarized below. This specification is focused on the force required to pull open a seam of a package. It is vital to protect the contents of a package, especially when the package contains sterilized medic...
This article discusses how to perform a polyurethane foam tear strength test on a universal testing machine (polyolefin foams are tested similarly). Complete instructions for a foam tear strength test can be found in ASTM D3574 Test F which appli...
One method to measure the tack force / strength of an adhesive is to perform the "Loop Tack" test method described in specification ASTM D6195. The adhesives tested with this test are typically pressure sensitive adhesives (PSA) applied...
