ASTM D1621 outlines the testing procedure for determining the compressive properties of rigid cellular materials, particularly expanded plastics. Rigid cellular, or foamed, plastics are manufactured in different forms for a variety of construction-related applications. Properties common to cellular plastic include thermal insulation (heat loss or fire protection), sound absorption, high strength-to-weight ratio, and earthquake resistance. The properties possessed by any given cellular plastic are a product of its resin, its cellular structure (open vs. closed), and its density. Material properties reported during ASTM D1621 testing include compression strength, strain at compressive strength, yield points, and if requested, compressive modulus.

 

Testing System

Depending on the maximum expected forces, ASTM D695 can be performed on either a single column or dual column universal testing machine such as those available in Kason Electronic Series Universal Testing Machine
