This abstract is a brief summary of the referenced standard. This standard does c653 purport to address all of the safety concerns, if any, associated with its use. For that reason, a specific review and approval should be solicited from the responsible architect and engineer, or both, astj any exterior application of metal suspension systems in the construction of a new building or building modification.

The structural classification or grade of ceiling suspension systems shall be determined by the capability of main runners or nailing bars to support a uniformly distributed load. It is the c63 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These classifications shall be: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

The test methods included in this specification do not provide the means for making a astj evaluation of continuous beam systems, nor for assessing the continuity contribution to overall system performance.

Active view current version of standard. Ast structural classification of ceiling suspension systems shall be based on the load-carrying capacity of the main runners of the structural network.

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. Link to Active This link will always route to the current Active version of the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its c35.

However, the test methods can be used for evaluating primary structural members in conjunction with secondary members that interlock, as well as with those of noninterlocking type. Combining values from the two systems may result in non-conformance with the standard. Suspension system structural members shall conform to the following tolerance requirements: However, the test methods can be used for evaluating primary structural members in conjunction with secondary members that interlock, as well as with those of noninterlocking type.

Some suspension systems incorporate locking assembly details that enhance performance by providing some continuity or load transfer capability between adjacent sections of the ceiling grid.
