Standard Guide for Lock-Strip Gasket Glazing

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.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

DESIGN CONSIDERATIONS
5. General
5.1 Structural integrity and watertightness of a gasket glazing system is dependent on interaction of the several components
involved. These systems should be carefully designed and built.
6. Components
6.1 The major components of lock-strip gasket glazing and paneling systems are:
6.1.1 The supporting frame of metal, concrete, or other structural building materials,
6.1.2 Lock-strip gasket, serving as an elastomeric mechanical seal and as a retainer for panel or glass, and
6.1.3 Glass or panel infill.
6.1.4 The design of these components and their accessories are interrelated and the total system must be compatible.
7. Supporting Frames
7.1 Supporting frames are made of many materials, of which the more common are aluminum, steel, and concrete.
