(Guide)Standard Guide for Calculating Movement and Other Effects When Establishing Sealant Joint Width
Standard Guide for Calculating Movement and Other Effects When Establishing Sealant Joint Width
SCOPE
1.1 This guide provides information on performance factors such as movement, construction tolerances, and other effects that should be accounted for to properly establish sealant joint size. It also provides procedures to assist in calculating and determining the required width of a sealant joint enabling it to respond properly to those movements and effects. Information in this guide is primarily applicable to single- and multi-component, cold-applied joint sealants and secondarily to precured sealant extrusions when used with properly prepared joint openings and substrate surfaces.
1.2 Although primarily directed towards the understanding and design of sealant joints for walls for buildings and other areas, the information contained herein is also applicable to sealant joints that occur in horizontal slabs and paving systems as well as various sloped building surfaces.
1.3 This guide does not describe the selection and properties of joint sealants (), which are described by Guide C 1299, nor their use and installation, which is described by Guide C 1193.
1.4 For protective glazing systems that are designed to resist blast and other effects refer to Guide 1564 in combination with this guide.
1.5 This guide is not applicable to the design of joints sealed with aerosol foam sealants.
1.6 For structural sealant glazing systems refer to Guide C 1401 in combination with this guide.
1.7 The values and calculations stated in SI units are to be regarded as the standard. The values given in parentheses and inch-pound units are provided for information only. SI units in this guide are in conformance with IEEE/ASTM SI 10-1997.
1.8 The Committee having jurisdiction for this guide is not aware of any comparable standards published by other organizations.
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.
