ASTM C1884-23a
(Specification)Standard Specification for Manufactured Concrete Ballast Units
Standard Specification for Manufactured Concrete Ballast Units
SCOPE
1.1 This specification covers dry-cast, manufactured concrete units that are primarily used for ballast applications. These units are machine-made from hydraulic cement, water, and suitable mineral aggregates with or without the inclusion of other materials.
Note 1: The design of concrete ballast units systems for resisting wind uplift is beyond the scope of this specification. Building codes and other standards should be consulted in designing for wind uplift resistance.
Note 2: Previously, there were two standards that covered units used for ballast. Specification C1491 was for concrete roof pavers, primarily used for roof ballast and protection of roof membrane. Specification C1884 was for units for ballast for rooftop equipment. Due to the similarity in these units and application, this standard now serves as the single standard for manufactured concrete units used in all ballast applications.
1.2 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
