ASTM D1621 PDF

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.

Email addresses can d16211 contain letters, numbers and the following special characters: If deformations are significant, astj measured deformations differ significantly from those in other methods because of the compression sphere that forms and do not provide reproducible results.

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 challenges of testing to this standard are: ISOMethod B also describes direct compressive deformation measurement of the specimen.

Make sure that deflection is being recorded either automatically based on crosshead position or manually at 0. E Deflectometer Deflection Gauge. Test data is obtained, and from a complete load-deformation curve it is aatm 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 elasticity.

The values in parentheses are for information only. To reduce the possible effects from off-center loading, it is aetm to place the swivel seat in the base. The test specimens are centered between two compression platens photo below left and load is applied at a constant crosshead or actuator rate.

When you are ready to test your materials to this standard, please refer to the official ASTM D specification. Such applications require additional tests such as impact, creep, and fatigue. Additional measurement of compression platen movement by direct displacement measurement is not required. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.

Test specimens are placed between two parallel compression platen anvils which are compressed at a constant rate of displacement until the specimen deforms to a specified percentage of the specimen’s original height.
