What is ASTM standard for the tensile strength?
ASTM D638 is the most common testing standard for determining the tensile properties of reinforced and non-reinforced plastics. With the use of plastics being at an all-time high, it is critical that manufacturers be able to properly gauge the mechanical strength of their materials.
Why do we test tensile strength?
One of the most common mechanical testing methods, tensile testing, is used to determine the behavior of a sample while an axial stretching load is applied. Tensile testing is commonly used to determine the maximum load (tensile strength) that a material or a product can withstand.
What is ASTM standard for tensile testing of metals?
The ASTM E8 method covers the tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of yield strength, yield point, tensile strength, elongation, and reduction of area.
Does gauge length affect tensile strength?
The short answer is that it depends on the tensile property and the characteristics of the material being tested. For a given cross-sectional area and for any gauge length, different specimen geometries have no effect on the ultimate tensile strength and the yield strength of standard materials.
What units is the tensile strength test measured in?
Tensile strengths have dimensions of force per unit area and in the English system of measurement are commonly expressed in units of pounds per square inch, often abbreviated to psi.
What is astastm d1708?
ASTM D1708 is a test method used to determine the tensile and elongation properties of plastics in the form of standard microtensile test specimens. Microtensile test specimens consist of materials of any thickness up to 3.2 mm (1/8 in), including thin films.
How do you perform a microtensile test with ASTM d1708?
Cut and prepare the microtensile test specimens with a ASTM D1708 cutting die. Set the testing machine so that the distance between the grips is 22 mm (0.86 in). Place the specimen in the grips and apply tensile force at the specified crosshead speed.
What is the difference between ASTM D638 and d1708?
ASTM D1708 is typically used to compare to historical data. ASTM D638 offers a type V specimen for use when material is limited and offers modulus information.
