ASTM D1621 PDF
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.

Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. Select from list below: Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!
ISOMethod B also describes asttm compressive deformation measurement of astn specimen. The standards differ in the dimensions of the specimen and in the test execution. Alternately, all standards permit direct displacement measurement of the compression platen.
Touchstone Research Laboratory, Ltd. The brochure addresses the most prominent and widely-used standards in the materials testing industry for plastics. E Deflectometer Deflection Gauge. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Email addresses can only x1621 letters, numbers and the following special characters: Precisely measure the area of each specimen using the method recommended in the specification.
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.
Calculate compressive strength using the load amount at which wstm point in step four occurs first. Make sure that your samples are the correct size as indicated in the specification.
ASTM D Compressive Properties of Rigid Cellular Plastics How to Guide – ADMET
Touchstone has a large environmental chamber photo on right capable of conditioning a wide range of sample sizes. Planar Biaxial Testing Guide. Such applications d621 additional tests such as impact, creep, and fatigue. Automotive Interior Mechanical Testing Guide. Historical Version s – view previous versions of standard.
Compression tests on hard foam to ISO , ASTM D
For measurements to ISO Method BZwickRoell offers mechanical and optical travel measuring systems for the precise recording of specimen deformation. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Instron offers linear variable displacement transducers LVDTs for measurement directly from the platens. The preload function reduces the amount of operator interaction, saving time and improving accuracy. Available from a 1 mm 0.
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.
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.
The x series LVDTs can mount directly on the series compression platens. 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 self-aligning nature of this fixture will maximize the contact area between the platen and the specimen. Contact Us Request an S1621 Catalog. Contact our Engineers Today!
The tests cannot be considered significant for engineering design in applications differing widely from the load – time scale of the standard test.
