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. ASTM D is similar to ISO and describes a procedure for determining the compressive properties of rigid cellular materials. Similar to ISO , ASTM D is a testing standard designed to measure the compressive properties of rigid cellular plastics (i.e. foam).

They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.

ASTM D1621 – Compression Testing of Rigid Cellular Plastics
Onsite Training At Your Facility. Concrete, Asphalt and Rock.
To reduce the possible effects from off-center loading, it is preferred to place the swivel seat in the base. Link to Active This link will always route to the current Active version of the standard.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Test data is obtained, and from a complete load-deformation curve it is possible to compute the compressive stress at any load such as compressive stress at proportional-limit load or compressive strength at maximum load and to compute the effective modulus of elasticity. Instron offers linear variable displacement transducers LVDTs for measurement directly from the platens.

The self-aligning nature of this fixture will maximize the contact area between the platen and the specimen.

Software for Series Systems. Contact Us View Accessories Catalog. The preload function in Bluehill Universal software automatically moves the upper compression platen down to precisely touch the specimen at a pre-defined load. The test specimens are centered between two compression platens photo below left and load is applied at a constant crosshead or actuator rate.
Please confirm that you agree with our privacy and cookies policy to submit this form. After testing and analysis, compressive strength, modulus and deformation at maximum load are reported.

Touchstone has a large environmental chamber photo on right capable of conditioning a wide range of sample sizes. Swivel seating can be placed on the platen attached to the instrument’s base or load cell in the moving crosshead.
Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. If there are no material specifications, then the default conditions apply.
The challenges of testing to this standard are: Email addresses must contain the symbol. These test specimens are carefully prepared so the faces are parallel aatm each other and perpendicular to the sides.
The preload function reduces the amount of operator interaction, saving time and improving accuracy.
ASTM D – 16 Standard Test Method for Compressive Properties of Rigid Cellular Plastics
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Email aatm can only contain letters, numbers and the following special characters: The values in parentheses are for r1621 only. ASTM D specifies the test conditions for determining the compressive properties of rigid cellular materials, particularly expanded plastics.
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.
The x series LVDTs can mount directly on the series compression platens. The data obtained from the compression tests provide a standard method of obtaining data for d121 and development and quality control.
The tests cannot be considered significant for engineering design in applications differing widely from the load – time scale of the standard test. Subscribe to Instron News!
