This specification covers the standards for the quality and grading of crushed stone, crushed slag, and water-worn gravel intended for use as coarse mineral aggregate on built-up roofs. The crushed stone and gravel shall be hard, durable, opaque, and free of foreign substances. The crushed slag, on the other hand, shall be hard, air-cooled, and free of as well of any foreign particles. The specimens shall comply with the gradation and physical requirements prescribed herein and shall undergo testing which include a gradation test, moisture test, unit mass test, dust, and hardness test.

1.1 This specification covers the quality and grading of crushed stone, crushed slag, and water-worn gravel suitable for use as coarse mineral aggregate on built-up roofs.

1.2 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.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
