It is important to note that this property is not the same as the modulus of elasticity, Emeasured in tension, flexure, or compression. By means of our testing expertise and modular product design, we will help find the aastm that is right for you.
ASTM D Torsion Plastics Test Equipment
Therefore, it is advisable to refer to that material specification before using this test method. Historical Version s – view previous versions of standard. We are confident that we have what you are looking for.
Since it is possible that the specimen will be deflected beyond its elastic limit, the calculated value will not always represent the true modulus of rigidity within the elastic limit of the material. Test specimen used for torsion testing per ASTM D are rectangular in shape can are cut from compression molded sheets or extruded sheets of plastic.
ASTM D explains the determination of the stiffness characteristics of plastics over a wide range of temperatures through measuring the apparent modulus of rigidity, G, via a torsion test.
For many materials, it is possible that there is a specification that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. The values given in parentheses are for information only. Referenced Documents purchase separately The documents listed below satm referenced within the zstm standard but are not provided as part of the standard. Forms plastic test specimens from plastic particles Variable temperature and pressure to form samples to different specifications Capable xstm cooling the newly formed specimen at a user-specified time Outputs 9, kgf 10 ton of force.
ASTM D Calibration Service-cold plastic stiffness certification
The relationship between these properties is shown in Annex A1. Have a question about conducting the test for this standard? The apparent modulus of rigidity may be affected by the creep characteristics of the material.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Link to Active This link will always route to the current Active version of the standard.
Give our test engineers a call today for help configuring the best test machine and accessories according to your standard. Flexible Polymers and Coated Fabrics. Stamps test specimens from soft rubber, leather, or similar stock materials Consistant samples for consistant results Force outputs of kgf or 3, kgf 1 ton or 3 ton No need to press by hand.
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. Forms rubber or plastic test specimens from stock material or from individual particles Variable temperature and pressure to form samples to different specifications Capable of cooling the newly formed specimen at a user-specified time Force outputs of 9, kgf, 27, kgf, or 45, kgf 10 ton, 30 ton, or 50 ton.
In addition, the value obtained by this test method will also be affected by the creep characteristics of the material, since the load application time is arbitrarily fixed.
