About This Item
ASTM D6226 is the ASTM standard for determining the open cell content of rigid cellular plastics. It provides a clear test method for evaluating how much of a rigid foam’s internal structure is open, which can be an important factor in product performance and material selection. For manufacturers, laboratories, and purchasers, this standard helps support more consistent testing and clearer comparison of rigid cellular plastic materials during quality control, specification review, and compliance activities.
ASTM D6226 standard overview
The Standard Test Method for Open Cell Content of Rigid Cellular Plastics defines a laboratory approach for measuring open cell content in rigid foam materials. This helps characterize the internal structure of the plastic and provides a repeatable way to assess properties that may affect behavior in use. ASTM D6226 is commonly referenced when technical documentation, product evaluation, or procurement decisions depend on a consistent method for comparing rigid cellular plastics against specified requirements.
Where is ASTM D6226 used?
This standard is used in testing and quality control settings where rigid cellular plastics need to be evaluated for open cell content. It is relevant to laboratories, manufacturers, and material specifiers working with rigid foam products and related components. ASTM D6226 may be used during incoming inspection, production checks, research and development, or compliance verification when a consistent test method is needed to support material characterization and product acceptance.
Practical importance of ASTM D6226
ASTM D6226 matters because open cell content can influence how a rigid cellular plastic performs and how it is specified. Using a recognized test method supports more reliable comparison between products, reduces ambiguity in procurement, and strengthens quality control decisions. It can also help organizations document material performance in a standardized way, which is valuable when evaluating suppliers, reviewing technical requirements, or managing risk in engineering and manufacturing workflows.
