ASTM C717 is the ASTM standard for Standard Terminology of Building Seals and Sealants, providing a common vocabulary for discussing these materials and their use in construction. It helps manufacturers, specifiers, contractors, and technical teams communicate more clearly when evaluating products, writing documents, or reviewing performance-related information. By standardizing terminology, ASTM C717 supports consistency across procurement, quality control, and project coordination where seals and sealants are involved.

What is ASTM C717?

ASTM C717 defines the terminology used for building seals and sealants. As a terminology standard, it does not typically set product performance requirements; instead, it establishes consistent language for the terms commonly used in this technical area. That makes it a useful reference when interpreting related ASTM documents, comparing product information, or preparing specifications. For anyone working with building sealants or sealing applications, ASTM C717 helps reduce ambiguity and supports more reliable communication across teams.

Where is ASTM C717 used?

ASTM C717 is commonly used in construction-related documentation, product literature, and technical reviews involving building seals and sealants. It is especially useful in settings where precise wording matters, such as specification writing, submittals, testing references, and quality discussions. Because it focuses on terminology, the standard is relevant wherever sealant-related language appears in design, procurement, or installation workflows. ASTM C717 helps ensure that the same terms are understood consistently across project participants and technical documents.

Why is ASTM C717 important?

ASTM C717 is important because shared terminology helps improve consistency, reduce misunderstandings, and support better decision-making. In sealant-related work, unclear language can affect product selection, specification compliance, and quality review. Using ASTM C717 as a reference can help align communication between manufacturers, engineers, contractors, and purchasers. For organizations that rely on ASTM standards, it also supports more efficient documentation and a clearer basis for comparing technical information and related requirements.
