ASTM C587 is the ASTM standard for Standard Specification for Gypsum Veneer Plaster, providing a technical reference for the material’s expected characteristics and consistency. It is used by buyers, suppliers, and quality teams who need a common basis for evaluating gypsum veneer plaster products. By defining the specification in a formal ASTM format, this standard helps support clearer procurement, more consistent product control, and better alignment between material claims and project requirements.

Purpose of ASTM C587

The purpose of ASTM C587 is to establish a recognized specification for gypsum veneer plaster, so the material can be identified and evaluated against a shared technical baseline. As a standard specification, it is typically used to support product conformity, quality control, and clear communication between manufacturers and users. ASTM C587 helps reduce ambiguity in material selection by focusing attention on the properties and requirements expected for gypsum veneer plaster in commercial practice.

Common use cases of ASTM C587

ASTM C587 is commonly used when gypsum veneer plaster is being specified, manufactured, purchased, or inspected for compliance with a project or product requirement. It is relevant in documentation, submittals, and quality review workflows where a defined gypsum plaster specification is needed. In practice, the standard may support material comparison, acceptance decisions, and supplier communication for veneer plaster products intended for interior finishing applications.

Why ASTM C587 matters

ASTM C587 matters because a clear specification helps improve consistency in gypsum veneer plaster products and reduces uncertainty during procurement and acceptance. For technical teams, it provides a reliable reference for product evaluation and quality control. For purchasers and specifiers, it supports more confident comparison of materials and helps align expectations with a recognized ASTM standard. ASTM C587 can also lower risk by giving all parties a common specification language.
