(Specification)Standard Specification for Adhered Manufactured Stone Masonry Veneer Units
Standard Specification for Adhered Manufactured Stone Masonry Veneer Units
ABSTRACT
This specification establishes the minimum product requirements for adhered manufactured stone masonry veneer (AMSMV) units which are manufactured from cementitious materials, aggregates, air-entraining admixtures, concrete admixtures, coloring pigments, reinforcement fibers, and other components which are wet-cast into shapes simulating the appearance of stone, rocks found in nature, and other textures. It also addresses sampling, physical properties and testing, finish and appearance, product identification and packaging, and reporting.
SCOPE
1.1 This specification covers the minimum product requirements for adhered manufactured stone masonry veneer units applied as an adhered veneer to exterior and interior walls and structures suitable to receive units.
1.2 The property requirements of this specification apply at the time of delivery. This standard does not address the physical evaluation of installed units removed from service.
1.3 The units described by this specification are manufactured from a mixture of cement, normal or lightweight aggregates (or a combination of both), water, admixtures, other cementitious materials and other components which are wet-cast into shapes simulating the appearance of natural stone and other textures.
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.5 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes shall not be considered as requirements of the standard.
1.6 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.
Note 1: When particular features are desired such as surface textures or color these features should be specified separately. Suppliers should be consulted as to the availability of units having the desired features.
1.7 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.
