This specification covers the material characteristics, physical requirements, and sampling method appropriate to the selection of roofing slate for use as roof shingles. Slates not included in this specification are those containing soft carbonaceous ribbons. Roofing shall be classified either as Grade S₁, S₂, or S₃, wherein each grade shall meet specified breaking load, absorption, and depth of softening requirements.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers the material characteristics, physical requirements, and sampling appropriate to the selection of slate for use as roof shingles.

1.2 Slates not included in this specification are those containing soft carbonaceous ribbons. The wide variation in physical properties and composition of such ribbon slates render their service life uncertain under some conditions of use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
