Application Summary AI generated

This standard specifies the test method for determining the volume percentage of open and closed cells in rigid cellular plastics. It is applied in the quality control and material characterization of thermal insulation products, such as polyurethane and phenolic foams used in construction, refrigeration, and packaging industries. The method is critical for evaluating insulation performance, as higher closed-cell content directly correlates with lower thermal conductivity and moisture absorption.
