What is ASTM E8 standard?
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. Touchstone Engineers have performed both standard and customized ASTM E8 testing.
What ASTM test for tension is designated for plastics?
ASTM D638
ASTM D638 specifies methods for testing the tensile strength of plastics and other resin materials and for calculating their mechanical properties, and outlines accuracy requirements for the test frames and accessories used. This test method uses dumbbell-shaped specimens with either a 25 mm or 50 mm gauge length.
What care should be taken while performing a test on UTM?
The grips used in the testing machine must be properly serrated so that there is no chance of slippage of the specimen. If the specimen breaks due to any reason, other than the tensile stress, the test procedure should be discarded, and a new test must be performed on a fresh specimen.
How do you cite ASTM standards?
Start the reference string with the basic designation of the standard. For example, “ASTM Standard C33.” Add the edition or version, separated by a comma, from the basic designation. For example, “ASTM Standard C33, 2003.” If ASTM has published a revision, cite the revised version.
How do you test the tensile strength of plastic?
Test Procedure:
- Cut or injection mold your material into one of the five “dumbbell” shapes.
- Load the specimen into tensile grips.
- Attach the extensometer to the sample.
- Begin the test by separating the tensile grips at a constant rate of speed.
- End the test after sample break (rupture)
What does ASTM stand for?
(April 2014) (Learn how and when to remove this template message) ASTM International, formerly known as American Society for Testing and Materials, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.
What is in the ASTM standard?
ASTM Membership and Mission. Membership in ASTM is open to anyone who is interested,and includes industry users,consumers,manufacturers and academics among others.
What is ASTM testing method?
The ASTM B117 is a standard test carried out to determine the corrosive effect of salt on metallic objects. It is done by spraying salt on a specimen housed in a closed chamber. This is an accelerated form for atmospheric corrosion testing.
What is the meaning of ASTM standard?
What is the Meaning of ASTM Standard? ASTM International is a globally recognized standards organization that develops and publishes consensus technical standards for materials. ASTM was formed in 1898 to address the frequent rail breaks affecting the railroad industry.
