ASTM C557-03 (R2017) PDF Download

The ASTM C557-03 (R2017) standard provides guidelines for the performance and properties of adhesives used to bond the back surface paper of gypsum wallboard to wood framing. This specification establishes minimum standards for adhesives and includes test requirements and methods for determining their suitability for all thicknesses of gypsum wallboard.

The standard emphasizes the importance of quality control and product performance certification. It specifies various tests that should be conducted on the adhesive, including compression shear test, tensile test, gap filling or bridging characteristics test, freeze-thaw stability test, and accelerated adhesive aging test. These tests are designed to ensure that the adhesives meet the required standards and can be relied upon for effective bonding.

The ASTM C557-03 (R2017) standard is applicable to a wide range of stakeholders, including adhesive manufacturers, distributors, specifiers, architects, contractors, testing laboratories, and other professionals who are involved in the selection and application of adhesives for fastening gypsum wallboard to wood framing.
