ASTM C Standard Guide for Use in Selection of Liquid-Applied Sealants This guide covers general background information of the comparative evaluation and selection of liquid-applied sealants for use in building construction. Sealant replacement needs to be considered and when needed should be easily accomplished. The results of this method can be used in conjunction with other information to determine the overall performance of the sealant joint.
There are many factors that can affect service life including type of sealant polymer, sealant formulation, compatibility with adjacent materials, installation techniques or deficiencies, sealant joint design or lack thereofproper maintenance or lack thereofand environmental exposure, among others. These sealants are intended to be a structural component of sealed insulating glass IG units used in structural sealant glazing hereinafter referred to as SSG.
Sealant Standard Test Methods ASTM C a Standard Test Method for Staining and Color Change of Single- or Multicomponent Joint Sealants This test method covers an accelerated laboratory procedure to determine if a sample of a joint sealant will stain the substrate when in contract with masonry, concrete, or stone such as marble, limestone, sandstone, and granite.
This test method provides a means for estimating the quantity of initial material required to dispense in order to fill a cavity.
ASTM C1193 – 16
As a result of the information in 4. Protective glazing includes systems designed for use in applications subject to natural disasters such as hurricanes, earthquakes, windstorms and forms of forced entry such as blasts, burglary, and ballistic attack. You can submit an innovation for consideration here: Guide C should be consulted for information on generally accepted comparative values for the characteristics and properties of the more common generic types of liquid-applied sealant.
It presents guidelines for the use and application of the various materials, design of a sealant joint for a specific application, and environmental conditions and effects that are known to detrimentally affect a sealant joint. Including joints on buildings and related adjacent areas, such as plazas, decks, and pavements for vehicular or pedestrian use, and types of construction other than highways and airfield pavements and bridges.
It is the ashm of the user of this standard to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
It is possible that the strain applied to the sealant bead may result in the failure of a deficient substrate before effecting a failure in the sealant.
Hereinafter insulating glass is referred to as IG. It explains the properties and functions of various materials, such as sealant, sealant backing, and primer, among others; and, procedures such as, substrate cleaning and priming, and installation of the components of a sealed joint.
ASTM C Standard Test Methods for Release Papers Used With Preformed Tape Sealants These test methods cover laboratory procedures for evaluating the release characteristics of a release paper intended to be supplied in direct contact with a preformed tape sealant.
Guide C should be consulted for this information. These materials are generally used to serve as components of glazing systems. It is the responsibility of the user of this standard to astmm appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

It also provides information on the adhesive bond of the sealants to the tested substrates. ASTM C Standard Test Method for Effects of Laboratory Accelerated Weathering on Elastomeric Joint Sealants This test method covers a laboratory procedure for determining the effects of accelerated weathering on cured-in-place elastomeric joint sealants single- and multicomponent for use in building construction.
Link to Active This link will always route to the current Active version of the standard. ASTM C e1 Standard Test Method for Determining the Tensile Properties of an Insulating Glass Edge Seal for Structural Glazing Applications This test method covers a laboratory procedure for quantitatively measuring the tensile strength, stiffness, and adhesion properties of insulating glass edge seals that are used in structural sealant glazing applications.
Presently only certain silicone sealants are recognized as having the necessary durability for use as secondary sealant in IG units in SSG applications ASTM C Standard Specification for Precured Elastomeric Silicone Joint Sealants Precured elastomeric silicone joint sealants, hereinafter referred to as seal, are manufactured in flat, cured, extruded shapes and are primarily used to span joint openings in construction.
Only a silicone chemically curing sealant specifically formulated, tested, and marketed for structural sealant glazing is acceptable for a SSG system application. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Refer to for joint seal geometries. This guide focuses on large-scale remedies. The destructive procedure stresses the sealant in such a way as to cause either cohesive or adhesive failure of the sealant or cohesive failure of the substrate where deficient substrate conditions exist. Sealant Standard Guides and Practices ASTM C Standard Practice for Use of Sealants in Acoustical Applications This practice is a guide for the use of sealants to reduce the sound transmission characteristics of interior walls, ceilings, and floors by proper application of sealants to joints, voids, and penetrations normally found in building construction.
Cylindrical sealant backing serves one or more of the following functions: The values given in parenthesis are provided for information only.

ASTM C Standard Test Method for Indentation Hardness of Elastomeric-Type Sealants by Means of a Durometer This test method describes a laboratory procedure for determining indentation hardness of joint sealing compounds, single- and multicomponentintended for use in building construction.
These sealants ast generally formulated to withstand a maximum joint movement of 7. They are intended to serve as a water and air barrier. The method is intended to estimate the contents of the aerosol container 1 for purposes of label statements, and 2 to provide the user information needed to estimate job requirements.
This test method was previously written to include only hot applied sealants. The IG units described are used in structural silicone sealant glazing systems, herein referred to as SSG systems. This test method does not address the issue of the integrity of the hermetic seal or changes to the vision area in an IG unit.
