ASTM D 1056 is a standard specification that outlines the requirements for flexible cellular materials, also known as sponge or expanded rubber. These materials are made from natural or synthetic rubber and are characterized by their cellular structure. They are used in a wide range of applications, including insulation, cushioning, and sealing.
The standard covers the properties that must be met by these materials, including density, compression set, and resilience. It also includes test methods for determining these properties, as well as guidelines for classifying the materials based on their compression characteristics.
In addition to the requirements for the materials themselves, the standard also includes specifications for the packaging and labelling of the materials. This includes requirements for the size and shape of the packaging, as well as the information that must be included on the label.
Overall, ASTM D 1056 provides a consistent set of guidelines for manufacturers, suppliers, and users of flexible cellular materials. By adhering to these guidelines, manufacturers can ensure that their products meet the necessary requirements for performance and safety, while users can have confidence in the materials they are purchasing.
