    Significance and Use

    3.1 This guide provides information and guidelines for the design of lock-strip gasket glazing systems. For related standards, see Specifications C542, C716, and C963.

    1. Scope

    1.1 This guide covers the use of lock-strip gaskets in compliance with Specification C542 in walls of buildings not over 15° from a vertical plane. The prime performance considerations are weathertightness against air and water infiltration, and structural integrity under wind loads. Included are terminology, design considerations, and fabrication tolerances when using lock-strip gaskets in glazing applications.

    1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information only.

    1.3 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.
