ASTM C28/C28M is the Standard Specification for Gypsum Plasters, providing a technical basis for identifying and evaluating gypsum plaster products. It helps define the requirements that support consistent product quality, reliable procurement, and clearer compliance decisions. For manufacturers, specifiers, and purchasers, this standard offers a practical reference point when comparing gypsum plaster materials intended for construction and finishing applications.

ASTM C28/C28M standard overview

ASTM C28/C28M focuses on the specification requirements for gypsum plasters, making it a useful document for product qualification and quality control. As an ASTM standard, it is intended to help align material expectations with recognized technical criteria rather than informal descriptions. The Standard Specification for Gypsum Plasters is commonly used to support consistent evaluation of product properties and to reduce ambiguity in purchasing or submittal documents.

Where is ASTM C28/C28M used?

This standard is commonly used in settings where gypsum plaster materials are selected, supplied, or reviewed for construction work. It is relevant to product manufacturers, distributors, testing laboratories, and project teams that need a clear specification reference for gypsum-based plaster products. ASTM C28/C28M may also be consulted during submittal review, purchasing, and technical comparison of materials intended for interior plastering or related finishing work.

Practical importance of ASTM C28/C28M

ASTM C28/C28M matters because it supports more consistent product decisions and helps reduce uncertainty during specification and procurement. By using a recognized standard for gypsum plasters, stakeholders can better compare products, document compliance, and support quality control processes. It is especially useful when a project requires a dependable technical benchmark for material acceptance, helping limit misunderstandings between suppliers, specifiers, and end users.
