【国外标准】 Standard Specification for Installing Lock-Strip Gaskets and Infill Glazing Materials

3.1 This specification can be referred to in contract documents as a method and workmanship standard for the installation of lock-strip gasket glazing systems. See also related standards (Specifications C542 and C963, Guide C964, and Terminology C717).AbstractThis specification covers installation procedures for lock-strip gaskets and for infill glazing materials in lock-strip gasket glazing applications used in building walls. The prime performance considerations are weathertightness against air and water infiltration, and structural integrity under wind loads. H-type gasket and reglet-type gasket are types of single-opening gasket systems which should be installed according to the specified requirements. Installation of multiple-opening gasket systems shall be classified as: unsupported vertical ladder assembly; unsupported horizontal ladder assembly; supported vertical ladder assembly; supported horizontal ladder assembly; and grid assembly. Installation of stick system, glass or panel into gasket, and lock-strip shall be in accordance with the requirements specified.1.1 This specification covers installation procedures for lock-strip gaskets that comply with Specification C542 and for infill glazing materials in lockstrip gasket glazing applications used in building walls which are not more than 15° from a vertical plane. The prime performance considerations are weathertightness against air and water infiltration, and structural integrity under wind loads.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only.1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.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.
