ASTM C22/C22M is the ASTM standard that defines the Standard Specification for Gypsum, providing a clear technical reference for evaluating gypsum material. It helps buyers, specifiers, and quality teams understand the basic requirements associated with this widely used material. By offering an agreed-upon specification, ASTM C22/C22M supports more consistent procurement, comparison, and product acceptance across different applications.

What is ASTM C22/C22M?

This ASTM standard is a specification for gypsum, meaning it establishes the requirements that the material is expected to meet for common commercial and engineering use. As a product-page reference, ASTM C22/C22M is useful when a project or purchasing document needs a recognized basis for material conformity. It serves as a technical guide for identifying whether gypsum offered for sale or use aligns with the standard’s stated requirements.

Where is ASTM C22/C22M used?

ASTM C22/C22M is commonly used wherever gypsum is purchased, specified, or checked against a formal material standard. It may be referenced by suppliers, laboratories, inspectors, and procurement teams involved in gypsum production or acceptance. The standard is most relevant in workflows that rely on product specification, receiving inspection, and documentation review, especially when gypsum quality and consistency must be verified against an ASTM reference.

Why is ASTM C22/C22M important?

This standard matters because it gives stakeholders a common basis for communication and compliance when working with gypsum. ASTM C22/C22M can help reduce ambiguity in purchasing and evaluation, support quality control, and make it easier to compare products from different sources. For organizations that rely on specification-based buying or acceptance testing, using a recognized ASTM standard can lower risk and improve consistency across projects.
