ASTM C1472-16e1 PDF Download

ASTM C1472-16e1 provides information and procedures for properly determining the width of a sealant joint in order to account for factors such as movement, construction tolerances, and other effects. The guide primarily applies to single- and multi-component, cold-applied joint sealants, as well as precured sealant extrusions when used with properly prepared joint openings and substrate surfaces.

The guide highlights the importance of understanding performance factors and tolerances in sealant joint design to ensure durability and effectiveness in maintaining a seal against air and water passage. Failure in sealant joint performance can lead to increased building energy usage, water infiltration, deterioration of building systems and materials, personal injury, and compromised indoor air quality. The guide emphasizes the significance of proper workmanship in the installation of sealant and sealant joint components to achieve adequate performance.

It is applicable to sealants with an established movement capacity, particularly elastomeric sealants meeting Specification C920 with a minimum movement capacity rating of ±12.5 percent. While sealants with lower movement capacity can be used with the joint width sizing calculations, the resulting joint width may become impractically large for installation. The guide can be used for designing joints in new construction, routine maintenance, and remedial work for failed joints. Additionally, it references other ASTM publications for further information and examples of sealant joint width calculations.

The guide does not cover the selection, properties, use, and installation of joint sealants, which are described by Guide C1193. It is also not applicable to joints sealed with aerosol foam sealants. For specific applications such as protective glazing systems or structural sealant glazing systems, the guide recommends referring to other relevant ASTM guides in combination with ASTM C1472-16e1. The values and calculations provided in the guide are stated in SI units, with inch-pound units given for information only. The standard is unique to ASTM and does not have comparable standards published by other organizations.
