Such applications require additional tests such as impact, creep, and fatigue. Warning—The explanation of r and R are only intended to present a meaningful way of considering the approximate precision of this test method. The preload function in Bluehill Universal software automatically moves the upper compression platen down to precisely touch the specimen at a pre-defined load.

ASTM D1621 – Compression Testing of Rigid Cellular Plastics

Touchstone Research Laboratory, Ltd. For each material, all of the samples were axtm at qstm source, but the individual specimens were prepared at the laboratories that tested them. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.

Current edition approved April 1, On each specimen test curve at each given load value, subtract the system compliance from each recorded displacement value. Link to Active This link will always route to the current Active version of the standard. Originally approved in ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in ast, standard.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

It is obtained by pooling the within-laboratory standard deviations of the test results from all of the participating laboratories.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Contact Us View Accessories Catalog. 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.

Care should be taken so that the loaded ends of the specimen are parallel to each other and perpendicular to the sides. This variance is a function of load frame stiffness, drive system wind-up, load cell compliance and? Each test result was the average of seven individual determinations.

Stop the crosshead and return to the pre-test location. WaveMatrix for Dynamic Testing. Test data is obtained, and from a complete load-deformation curve it is possible to compute the compressive stress at dd1621 load such as compressive stress at astmm load or compressive strength at maximum load and to compute the effective modulus of elasticity.

Such applications require additional tests such as impact, creep, and fatigue. We use cookies to improve your browsing experience. Specimen d isplacement and load are recorded throughout the test. This measurement is made through use of the test machine crosshead drive system or using a direct measurement of compression platen displacement.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
