ASTM D B1 is a testing specification that measures the indentation force deflection of urethane foam and foam-like substances. ASTM D C specifies a method for measuring the compression force necessary to produce a 50% deflection over the entire top surface of the foam test .

ASTM D is a widely accepted test standard for testing soft polyurethane foam. One specimen should be tested.
You are seeking to quantify the firmness of your foam. The initial height of the specimen is determined directly by the testing machine at the beginning of the first preload cycle.
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 applications. Have a question about conducting the test for this standard?
ASTM D3574 Testing Equipment for Flexible Cellular Urethane Foams
All of our test machines configured for ASTM D are supplied with perforated base plates for supporting the foam samples. There is a wide range of applications for D including car seats, furniture, mattresses, bedding, pillows, foam products and materials, and bolsters. The and are lower force options best for foam testing, the having more test space for larger specimens. Our engineers are very familiar with foam testing to ASTM D and can help guide you through the process with the correct compression test machine.
The Universal Test Machine would be used for higher forces or very large specimens. ASTM D specifies an additional specimen with a round cross-section and a diameter of 57 mm. Tear test to determine the tear propagation resistance of foam. The methods used by Renault and PSA are exceptions.
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 standard specimen for this test is 50mm X 50mm X 25 mm thick or larger.
If possible a completed manufactured product should be used as your testing specimen. For Test F, specimens are generally about mm long blocks with the width and depth the same as the material pad thickness.
For Test M recovery time is measured in seconds. These specialized base plates allow air to escape from the foam during compression. There atsm several test procedures in this standard to help astn the compression, deflection, tear and tensile characteristics of flexible cellular materials urethane foams and polyurethane foams. The test consists of a total of five test cycles, of which the first and the last are evaluated.
Recovery time tests determine the recovery time of slow recovery memory foams.
ASTM D Testing Equipment for Flexible Cellular Urethane Foams
Measurements are asttm for tensile stress, tensile strength, and ultimate elongation. Samples come in a variety of forms including slab, bonded, and molded flexible cellular urethane foams. These correction options are available with all ZwickRoell testing machines as a standard function. According to ASTM Dthe height and travel-zero point is redetermined before the measuring cycle. Cuts test specimens from stock material Available for a wide variety of ISO and ASTM standards Consistent specimens for consistent results Manufactured with tool steel to resist damage and wear over time.
ProLine for standardized tests ProLine testing machines are specifically designed for function-testing components and for routine materials testing. In this v3574, the deformation behavior of the specimen is relatively complex.
GK mechanical vice grips can also be used. In order to be able to certify your results you need a test machine that was designed and built to the details of the standard, and you need to adtm the test exactly as the standard directs. AllroundLine for individual testing requirements and all applications The optimum solution for demanding testing applications, whether in quality control or for research projects.
These versatile test machines can be configured s3574 test in both tensile and compression. This test will measure the IFD properties of the foam specimen asstm and after fatigue cycling.
IFD Indentation force deflection and ILD indentation load deflection are two of the more common compression tests in this standard. For this reason it is not possible to effectively compare measured values that are determined from specimens of various dimensions using this test method. Density is measured using a scale that is connected to the PC.
