About This Item
ASTM C864 is the ASTM standard that addresses dense elastomeric compression seal gaskets, setting blocks, and spacers, helping define a clear technical basis for evaluating these components. It matters because these materials are often used together in assemblies where fit, compression behavior, and positioning can affect performance. By providing a consistent specification framework, ASTM C864 supports product selection, procurement, and quality control for related gasket and support components.
What is ASTM C864?
ASTM C864 is the Standard Specification for Dense Elastomeric Compression Seal Gaskets, Setting Blocks, and Spacers. As a technical document, it is intended to establish requirements for these related products so they can be identified, compared, and evaluated consistently. The standard is relevant when dense elastomeric materials are selected for compression sealing and for supporting or spacing functions within an assembly. ASTM C864 helps provide a common reference point for manufacturers, specifiers, and purchasers.
Where is ASTM C864 used?
ASTM C864 is commonly used in projects and workflows that involve compression seal gasket materials along with setting blocks and spacers. It is most relevant where these components must be matched for assembly, installation, or specification review. The standard can support purchasing decisions, submittal review, and product verification when dense elastomeric components are needed for controlled fit and positioning. ASTM C864 is especially useful in technical environments that require consistent material and dimensional expectations.
Why is ASTM C864 important?
ASTM C864 is important because it helps reduce ambiguity when specifying or evaluating dense elastomeric compression seal gaskets, setting blocks, and spacers. A recognized ASTM standard supports more consistent product comparison, clearer procurement language, and better quality control. It can also help reduce risk by aligning expectations for compliance and technical acceptance. For manufacturers and buyers alike, ASTM C864 offers a practical benchmark for documentation, verification, and specification management.
