ASTM C1047 is the ASTM standard that addresses accessories for gypsum wallboard and gypsum veneer base, providing a technical reference for products used alongside these interior finishing materials. It helps define the expectations for accessory items so they can be selected, evaluated, and used with greater consistency in wall and ceiling construction. For procurement, quality control, and product comparison, this specification offers a clear basis for understanding accessory requirements tied to gypsum board applications.

Purpose of ASTM C1047

The purpose of ASTM C1047 is to establish a specification framework for accessories intended for use with gypsum wallboard and gypsum veneer base. As a product-focused ASTM standard, it supports more consistent evaluation of accessory materials that contribute to installation performance and finish quality. The document is useful when comparing products, verifying conformance, or coordinating construction requirements around gypsum-based interior systems. In that sense, ASTM C1047 helps bring clarity to accessory selection and specification.

Common use cases of ASTM C1047

This standard is commonly referenced when specifying or purchasing accessories used with gypsum wallboard and gypsum veneer base in interior construction work. It may be used by manufacturers, distributors, contractors, and specifiers who need a common technical basis for accessory products associated with these systems. ASTM C1047 can also support submittals, product evaluation, and project documentation where consistency and compatibility with gypsum board assemblies are important.

Why ASTM C1047 matters

ASTM C1047 matters because accessory products can affect how gypsum wallboard and gypsum veneer base systems perform and finish in practice. A clear specification supports better compliance checks, more consistent procurement, and improved quality control across projects. It also helps reduce ambiguity when comparing products or reviewing technical documents. For organizations working with gypsum-based interior systems, ASTM C1047 provides a reliable reference for evaluating accessory suitability and maintaining uniform standards.
