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.

Note that the standards are similar but not the same. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. The preload function in Bluehill Universal software automatically moves the upper compression platen down to precisely touch the specimen aatm a pre-defined load.
Compression Test on Hard Foam
Planar Biaxial Testing Guide. Any test specimen preparation, conditioning, dimensions, or testing parameters, or aatm combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method.
ASTM D Testing is the compressive strength of a cellular material determined by applying load to a test specimen with a square or circular cross section. If deformations are d16211, the measured deformations differ significantly from those in other methods because of the compression sphere that forms and do not provide reproducible results. Alternately, all standards permit direct displacement measurement of the compression platen.
Compression tests on hard foam to ISO , ASTM D
The values in parentheses are for information only. Such applications require additional tests such as impact, creep, and fatigue. Two rigid compression platens can be employed but then a deflectometer is recommended to minimize error due to compliance from the system.
It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.
Next Checking to see if you are a returning visitor…. This makes it possible to effectively determine compression platen movement asgm a accuracy of over 5 micrometers. E Deflectometer Deflection Gauge.
Link to Active This link will always route to the current Active version of the standard. These test specimens are carefully prepared so the faces are parallel to each other and perpendicular to the sides. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. 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.
It is the responsibility astk the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Rigid Cellular Plastic Compression Properties (ISO 844 and ASTM D1621)
To reduce the possible effects from off-center loading, it is preferred to place the swivel seat in the base.

ASTM D – 10 Standard Test Method for Compressive Properties Of Rigid Cellular Plastics
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. AllroundLine for individual testing requirements and all applications The optimum solution for demanding testing applications, whether in quality control or for research projects.
Continue to apply load until the sample yields or until the sample has been compressed to the percentage of original thickness indicated in the standard. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: When you are ready to test your materials to this standard, please refer to the official ASTM D specification. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Please confirm that you agree with our privacy and cookies policy to submit this form.
The parallelism of the platens is important so spherical seated self aligning platens are used along with a fixed height platen.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Rigid foams are typically used in the construction industry as sound and thermal insulation.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Available from a 1 mm 0. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.
The x series LVDTs can mount directly on the series compression platens. Make sure that your samples are the correct size as indicated in the specification. The system can also be connected to a defectometer to provide more accurate deflection data.
