ASTM WK65789

    New Test Method for Strength Properties of Direct Hung, Suspended T-Bar-Type Ceiling System Components Intended to Receive Gypsum Panel Products

    (What is a Work Item?)

    Developed by Subcommittee: C11.02 | Committee C11 | Contact Staff Manager


    1. Scope

    1.1 This test method covers metal ceiling suspension systems used primarily to support screw-attached gypsum panel products. 1.2 The method of determining strength properties of suspended ceiling grid system components is: Tests--Uniform Load Carrying Capacity,Section 6; Connection Strength in Tension and Compression,Section 7; and Wire Pullout Resistance, Section 8. 1.3 Units--The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the 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 and health practices and determine the applicability of regulatory limitations prior to use.


    DGS; drywall grid


    No standard for testing drywall grid components exists. This standard will be used by manufacturers, third-party testing laboratories, and code-compliant evaluation services.

    The title and scope are in draft form and are under development within this ASTM Committee.
