Standard Practice for Installation of Metal Ceiling Suspension Systems for Acoustical Tile and Lay-In Panels

Abstract

This practice covers the standard procedures for the installation of metal ceiling suspension systems for acoustical tile and lay-in panels. Here, specifications are provided for the installation of individual components such as hangers, carrying channels, main runners, cross runners, splines, assembly devices, and ceiling fixtures. Specifications are also given for possible interference of ceiling related components, and the lighting and appearance.

Scope

1.1 This practice covers the installation of suspension systems for acoustical tile and lay-in panels. It is applicable to contractors whose services are utilized for installing acoustical ceilings and to other trades if their activities are responsible for interference with ceiling components or performance as defined in this recommended practice.

1.2 While the practices described in this document have equal application to fire-resistive suspension systems, many systems impose additional requirements to obtain the fire endurance classification of particular floor-ceiling or roof-ceiling assemblies. These details are available from the listing agency and from the manufacturers.

1.3 Similarly, additional detailing is often necessary to meet sound attenuation requirements when ceiling plenums extend over contiguous rooms. Obtain these from the manufacturer of the acoustical material employed.

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 exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems result in non-conformance with the standard.

1.5 While many of the practices described in this practice have application to the installation of metal suspension systems in exterior environments, the specific design of exterior ceiling installations requires the review and approval of the architect or engineer, or both, who are responsible for the construction of the building or modifications to an existing building. While recommendations from the manufacturer are solicited, it remains the final responsibility of the architect/engineer to ensure proper application of the materials in question.

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.

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.
