ASTM C587-04 (R2018) PDF Download

The ASTM C587-04 (R2018) standard covers the requirements for calcined gypsum mixed with other ingredients to control its working quality and setting time. This type of plaster is specifically designed to be used as a veneer plaster, applied over a gypsum base or on masonry or concrete surfaces. The maximum thickness allowed for this veneer plaster is 1/4 inch (6.4 mm), and it is intended to provide a surface that is ready for decoration.

The standard also includes test methods for determining the physical properties of gypsum veneer plasters. These tests assess the joint strength, bond strength, impact strength, and flexure of the plaster. The veneer plasters must meet specified values for these properties in order to conform to the standard.

It is important to note that this specification references notes and footnotes throughout the text, which provide additional explanatory information. However, these notes and footnotes should not be considered as requirements of the standard itself.
