ASTM D specifies the test conditions for determining the compressive properties of rigid cellular materials, particularly expanded plastics. Rigid foams. 22 Feb Similar to ISO , ASTM D is a testing standard designed to measure the compressive properties of rigid cellular plastics (i.e. foam). This standard is issued under the fixed designation D ; the number 1 This test method is under the jurisdiction of ASTM Committee D on Plastics.

Planar Biaxial Testing Guide. Any test specimen preparation, conditioning, dimensions, or testing parameters, or a combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method. This post is intended to help you understand the basic test procedure and the equipment needed to perform this test with certainty. Link to Active This link will always route to the current Active version of the standard.


Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more. Precisely measure the area of each specimen using the method recommended in the specification.

sstm Swivel seating can be placed on the platen attached to the instrument’s base or load cell in the moving crosshead. The Plastics Testing Solutions brochure is a page, applications-focused, and standards-based brochure. MTESTQuattro software controller is capable of graphically displaying deflection based on crosshead position in real-time. ProLine for standardized tests ProLine testing machines are specifically designed for function-testing components and for routine materials testing.

Touchstone has a large environmental chamber photo on right capable of conditioning a wide range of sample sizes. When you are ready to test your materials to this standard, please refer to the official ASTM D specification.

Available from a 1 mm 0. The test specimens are centered between two compression platens photo below left and load is applied at a constant crosshead or actuator rate. The tests cannot be considered significant for engineering design in applications differing widely from the load – time scale of the standard test. Email addresses can only contain letters, numbers and the following special characters: Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Atm to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.

Calculate compressive strength using the load amount at which ever point in step four occurs first. These test specimens are carefully prepared so the faces are parallel to each other and perpendicular to the sides.

While in EN and ISO the movement of the compression platen is typically measured by the crosshead travel of the testing machine with a defined minimum accuracy, ASTM D describes an additional method that compensates for the self-deformation of the testing machine. Suitable systems for this application include Series and Series electromechanical testing machines equipped with compression platens.

The preload function reduces the amount of operator interaction, saving time and improving accuracy. If deformations are significant, the measured deformations differ significantly from those in other methods because of the compression sphere that forms and do not provide reproducible results.

Select from list below: Atsm foams are typically used in the construction industry as sound and thermal insulation. Such applications require additional tests such as ashm, creep, and fatigue. The values in parentheses are c1621 information only.

Two rigid compression platens can be employed but then a deflectometer is recommended to minimize error due to compliance from the system. After testing and analysis, compressive strength, modulus and deformation at maximum load are reported.

The data obtained from the compression tests provide a standard method of obtaining data for research and development and quality control.

The self-aligning nature of this fixture will maximize the contact area between the platen and the specimen. Specimen d isplacement and load are recorded throughout the test.

Our website uses cookies to ensure that we give you the best user experience. Instron offers linear variable displacement transducers LVDTs for measurement directly from the platens.

Touchstone Research Laboratory, Ltd. The challenges of testing to this standard are: ISOMethod B also describes astj compressive deformation measurement of the specimen.

We use cookies to improve your browsing experience. The parallelism of the platens is important so spherical seated self aligning platens are used along with a fixed height platen.

Alternately, all standards permit direct displacement measurement of the compression platen.
