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 ...
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...
In the ASTM acceptance standard for testing rubber surgical gloves (D3577) and rubber medical gloves (D3578), made of latex, vinyl, and nitrile. The standard describes the standard size, material properties, physical and mechanical property acceptance ...
This test shows a textile ribbon being pulled apart at a constant rate of speed until it breaks. Measurements include the force required to break the sample and the amount the material stretched before breaking (elongation).
This article discusses foam tensile strength testing. A foam tensile strength test can be found in ASTM D3574 Test E which applies to slab, bonded, and molded flexible cellular urethane foams. There are many tests in this specification including...
Nitinol is a metal alloy composed of titanium and nickel. nitinol is characterized by its biocompatibility, elasticity, fatigue strength, and ability to return to its original shape after deformation (shape memory). Although nitinol is used in industri...
