ASTM C629/C629M-15

Standard Specification for Slate Dimension Stone

ABSTRACT
This specification covers the material characteristics, physical requirements, and sampling method appropriate to the selection of slate dimension stone for general building and structural purposes. Dimension slate shall include stone that is sawed, cut, split, or otherwise finished or shaped, and shall specifically exclude molded, cast, or otherwise artificially aggregated units composed of fragments, and also crushed and broken stone. It specifically excludes roofing slate and slate for industrial uses. Slates shall be selected for either exterior or interior use. The physical property requirements to which slate stones shall adhere to are absorption, abrasion resistance, acid resistance, and modulus of rupture (across grain and along grain).
SCOPE
1.1 This specification covers the material characteristics, physical requirements, and sampling appropriate to the selection of slate for general building and structural purposes. Refer to Guides C1242 and C1528 for the appropriate selection and use of slate dimension stone.  
1.2 Dimension slate shall include stone that is sawed, cut, split, or otherwise finished or shaped, and shall specifically exclude molded, cast, or otherwise artificially aggregated units composed of fragments, and also crushed and broken stone.  
1.3 It specifically excludes roofing slate (see Specification C406/C406M) and slate for industrial uses.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
