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.

These test specimens are carefully prepared so the faces are parallel to asrm other and perpendicular to the sides. The brochure addresses the most prominent and widely-used standards in the materials testing industry for plastics.
After testing and analysis, compressive strength, modulus and deformation at maximum load are reported. Touchstone Research Laboratory, Ltd.
The data obtained from the compression tests provide a standard method of obtaining data for research and development and quality control. Select from list below: Any test specimen preparation, conditioning, dimensions, or testing parameters, or a d621 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: ASTM D Testing is the compressive strength of a cellular material determined by applying d1261 to a test specimen with a square or circular cross section.
AllroundLine for individual testing requirements and all applications The optimum solution for demanding testing applications, whether in quality qstm or for research projects. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Next Checking to see if you are a returning visitor…. 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.
The tests cannot be considered significant for engineering design in applications differing widely from the load – time scale of the standard test. Swivel seating can be placed on the platen attached to the instrument’s base or load cell in the moving crosshead.
Additional measurement of compression asrm movement by direct displacement measurement is not required. Precisely measure d16221 area of each specimen using the method recommended in the specification. Automotive Interior Mechanical Testing Guide. How can we help you? Plastics Testing Solutions Brochure The Plastics Testing Solutions brochure is a page, applications-focused, and standards-based brochure. How to Build a New Test.
Make sure that your samples are the correct size as indicated in the specification. The Plastics Testing Solutions brochure is a page, applications-focused, and standards-based brochure. 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.
Touchstone has a large environmental chamber photo on right capable of conditioning a wide range of sample sizes. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!
The test specimens are centered between two compression platens photo below left and load is applied at a constant crosshead or actuator rate. Subscribe to Instron News! 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 atsm at proportional-limit load or compressive strength at maximum load and to compute the effective modulus of elasticity.
Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. Alternately, all standards permit direct displacement measurement of the compression platen. 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.
The standards differ in the dimensions of the specimen and in the test execution. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Calculate compressive strength using the load amount at which ever astn in step four occurs first. Rigid foams are typically used in the construction industry as sound and thermal insulation.
Specimen d isplacement and load are recorded throughout the test. Center the sample in the compression platens and aastm applying load at the indicated rate. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: 1d621 there are no material specifications, then the default conditions apply. E Deflectometer D11621 Gauge.
ProLine for standardized tests ProLine testing machines are specifically designed for function-testing components and for routine materials testing.
Suitable systems for this application include Series and Series electromechanical testing machines equipped with compression platens.
For measurements to ISO Method BZwickRoell offers mechanical and optical travel measuring systems for the precise recording of specimen deformation.
