ASTM D1621 PDF

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).

ASTM D – 16 Standard Test Method for Compressive Properties of Rigid Cellular Plastics

The challenges of testing to this standard are: 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. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Swivel seating can be placed on the platen attached to the instrument’s base or load satm in the moving crosshead.

The values in parentheses are for information only. To reduce the possible effects from off-center loading, it is preferred to place the swivel seat in the base. The data obtained from the compression tests provide a standard method of obtaining data for research and development and quality control. Next Checking to see if you are a returning visitor…. Such applications require additional tests such as impact, creep, and fatigue.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Bluehill LE for Basic Testing. The test specimens are centered between two compression platens photo below left and load is applied at a constant crosshead or actuator rate. The preload function reduces the amount of operator interaction, saving time and improving accuracy.

ASTM D specifies the test conditions for determining the compressive properties of rigid cellular materials, particularly expanded 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 zstm. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.

Specimen d isplacement and load are recorded throughout the test. ASTM D 1d621 is the compressive strength of a cellular material determined by applying load to a test specimen with a square or circular cross section. 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.

Onsite Training At Your Facility. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. After testing and analysis, compressive strength, modulus d16621 deformation at maximum load are reported.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. The tests cannot be considered significant for engineering design in applications differing widely from d161 load – time scale of the standard test. Touchstone Research Laboratory, Ltd. If there are no material specifications, then the default conditions apply.

Rigid foams are typically used in the construction industry as sound and thermal insulation. The x d11621 LVDTs can mount directly on the series compression platens. Description Literature Contact Us ASTM D specifies the test conditions for determining the compressive properties of rigid cellular materials, particularly expanded plastics.

Suitable systems for this application include Series and Series electromechanical testing machines equipped with asgm platens. Glossary of Materials Testing Terms. The self-aligning nature of this fixture will maximize the contact area between the platen and the specimen. The preload function in Bluehill Universal software automatically moves the upper compression platen down to precisely touch the specimen at a pre-defined load.
