    1. Scope

    1.1 This practice is intended to provide accepted procedures to designers and installers of adhered manufactured stone masonry veneer in residential and commercial construction. This information is meant to complement the specific installation instructions provided by manufacturers of adhered manufactured stone masonry veneers and recognized building codes, but is not meant to replace them. This practice does not address installation methods or techniques for all materials in the building envelope. This practice covers the installation of adhered manufactured stone masonry veneer units for application as adhered veneer to exterior and interior walls, columns, landscape structures and other structures suitable to receive adhered veneer. The units included in this practice are manufactured to meet the requirements of Specification C1670/C1670M. This practice is limited to the installation of units. This practice does not cover all flashing or moisture management requirements. Refer to the applicable building code and project documents for additional flashing and moisture management requirements.

    Note 1: The Masonry Veneer Manufacturers Association (MVMA) publication Installation Guide for Adhered Concrete Masonry Veneer provides generally accepted methods and details for installation and flashing.

    1.2 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.

    1.3 All workmanship and materials related to the installation of adhered manufactured stone masonry veneer units shall meet the requirements of the contract documents and building code having jurisdiction over the project.

    1.4 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.

    1.5 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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)

    1.6 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.
