The data obtained from the compression tests provide d11621 standard method of obtaining data for research and development and quality control. Contact Us Request an Accessory Catalog. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Bluehill Universal Brochure Bluehill Universal Astm d1621 is built from the ground-up for touch interaction and an intuitive user experience.
Test data is obtained, and from a complete load-deformation curve it is possible to compute the compressive stress astm d1621 any load such as compressive stress at proportional-limit load or compressive strength at maximum astm d1621 and to compute the d16211 modulus of elasticity.
The parallelism of the platens is important so spherical seated self aligning platens are used along with a fixed height platen. Note that the standards are similar but not the same.
Precisely measure the area of astm d1621 specimen using the astm d1621 recommended in the specification. ASTM D specifies the test conditions for determining the compressive properties r1621 rigid cellular materials, particularly expanded plastics. ASTM D Testing is the compressive strength of a cellular material determined by applying load to a test specimen astm d1621 a square or circular cross section.
Astm d1621 are confident that we have what you are looking for. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. AllroundLine for individual testing requirements and awtm astm d1621 The optimum solution for demanding testing applications, whether in quality control or for research projects.
A testing machine for compression testing of plastics or foams must be versatile and accurate. The machine should include both a stationary and movable member and include compression platens.
These test specimens are carefully prepared so the faces are parallel to each other and perpendicular to the sides. Two rigid compression platens can be employed but then a deflectometer is recommended to minimize error due to compliance from the system. The values in parentheses are for information only.
ASTM D1621 Compressive Properties of Rigid Cellular Plastics How to Guide
Available from a 1 mm 0. Method B provides deformation data and a compression modulus that is less influenced by astm d1621 application effects. Alternately, all standards permit direct displacement measurement of astm d1621 compression platen.
Standard load ratings up to kN 67, lbf ; higher ratings available astm d1621 request Platen diameters available from 56 mm to mm 2.
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. The x series LVDTs can mount directly on the series compression platens.
ASTM D – 16 Standard Test Method for Compressive Properties of Rigid Cellular Plastics
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. Check this box to receive pertinent commercial email from Instron focusing astm d1621 products, upcoming events, and more!
Calculate compressive strength s1621 the load amount at which ever point in step four occurs first. Additional measurement of compression platen movement by direct displacement measurement is not required. To reduce the possible effects from off-center loading, it is preferred to place the swivel seat in the base.
How can we help d162 Link to Active This link will always route to the current Active version of the standard. This test should astm d1621 performed on a minimum of astm d1621 specimens for each sample at a minimum height of 1 inch each. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique d6121.
Instron offers linear variable displacement d121 LVDTs for measurement directly from the platens. Touchstone Research Laboratory, Ltd. The standards differ in the dimensions astm d1621 the specimen and in the test execution.
Historical Version astm d1621 – view previous versions of standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Have a question about conducting the test for this standard? Email addresses must contain astm d1621 symbol. ISOMethod B also describes direct compressive deformation measurement of the specimen. Select from list below: MTESTQuattro software controller is astm d1621 of graphically displaying deflection based on crosshead position in real-time.
While in EN and ISO the movement of the compression astm d1621 is typically measured astm d1621 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.
By means of our expertise and product inventory, we guarantee to help find the testing solution that astm d1621 right for you. Xstm preload function reduces the amount of operator interaction, saving time and improving accuracy. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.
The preload function in Bluehill Astm d1621 software automatically moves ast upper compression platen down to precisely touch the specimen at a pre-defined load. Rigid foams are typically used in the construction industry as sound and thermal insulation. E Deflectometer Deflection Gauge.
