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).

Such applications require additional tests such as impact, creep, and fatigue.

Rigid foams are typically used in the construction industry as sound and thermal insulation. Historical Version s – view previous versions of standard.

Select from list below: Subscribe to Our Newsletters. 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. These test specimens are carefully prepared so the faces are parallel to each other and perpendicular to the sides. Description Literature Contact Us ASTM D specifies the test conditions for determining the compressive properties of rigid cellular materials, aastm expanded plastics.

Concrete, Asphalt and Rock. Touchstone has a large environmental chamber photo on right d121 of conditioning a wide range of sample sizes. The brochure addresses the most prominent and widely-used standards in the materials testing industry for plastics. Touchstone Research Laboratory, Ltd.

Glossary of Materials Testing Terms. Swivel seating can be placed on the platen attached to the instrument’s base or load cell in the moving crosshead.

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 asttm elasticity. Email addresses must contain the symbol. Instron offers linear variable displacement transducers LVDTs for measurement directly from the platens.

Email addresses can only contain letters, numbers and the following special aatm It is important to review D16211 D in order to fully understand the test setup, procedure, and results requirements.

If there are no material specifications, then the default conditions apply. 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 Plastics Testing Solutions brochure is a page, applications-focused, and standards-based brochure.

The test specimens are centered between two compression platens photo below left and load is applied at a constant crosshead or actuator rate. To reduce the possible effects from off-center loading, it is preferred to place the swivel seat in the base. WaveMatrix 2 for Dynamic Testing. Software for Series Systems. Bluehill LE for Basic Testing. The x series LVDTs can mount directly on the series compression platens.
