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).

Touchstone Research Laboratory, Ltd. 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 data obtained from the compression tests provide a standard method of obtaining data for research and development and quality control.

ASTM D Testing is the compressive strength of a cellular material determined by applying load to a test specimen with a square or circular asym section. Concrete, Asphalt and Rock. Select from list below: After testing and analysis, compressive strength, modulus and deformation at maximum load are reported. Subscribe to Instron News!

ASTM D1621 – Compression Testing of Rigid Cellular Plastics

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

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 d16621 compute the effective modulus of elasticity.

The test specimens are centered between two compression platens photo below left and load is applied at a constant crosshead or actuator rate. Link to Active This link will always route to the current Active version of the standard.

Instron offers linear variable displacement transducers LVDTs for measurement directly from the platens. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. To reduce the possible effects from off-center loading, it is preferred to place the swivel seat in the base.

ASTM D – 16 Standard Test Method for Compressive Properties of Rigid Cellular 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. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: The brochure addresses the most prominent and widely-used standards in the materials testing industry for plastics.

The x series LVDTs can mount directly on the asgm compression platens. Asfm is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. Such applications require additional tests such as impact, creep, and fatigue.
