ASTM C Standard Guide for Evaluating Failure of Structural Sealant Glazing This guide covers a screening approach to detect failure adhesive or cohesive of a structural sealant in a structural sealant-glazed window, curtain wall, or other similar system. Presently, only a silicone-sealant that is specifically formulated, tested, and marketed as a structural glazing sealant is allowed for structural sealant glazing. ASTM C — 03 Standard Guide for In-Situ Structural Silicone Glazing Evaluation It is recommended to periodically evaluate the existing condition of structural sealant glazing hereinafter called SSG installations in situ to detect problems before they become severe or pervasive. Evaluation of existing SSG installations are required by certain building codes and local ordinances.

More C 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. 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.

The information and guidelines are also useful for those that supply accessories to the sealant industry and for those that install sealants and accessory materials associated with sealant use. Considering the range of properties of commercially available sealants, the variety of joint designs possible, and the many conditions of use, the information contained herein is general in nature.

However, a sealant and sealant joint will also have a service life. The intent is for service life to meet or exceed design life. 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 thereof , proper maintenance or lack thereof , and environmental exposure, among others.

The designer of a joint seal should take the above into consideration when designing and specifying sealants for certain applications. For example, a building owner may require a new courthouse building to have an expected design life of 50 years.

As a result of the information in 4. Sealant replacement needs to be considered and when needed should be easily accomplished. Scope 1. 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.

Information in this guide is primarily applicable to a single and multi-component, cold liquid-applied joint sealant and secondarily to a precured sealant when used with a properly prepared joint opening and substrate surfaces. Guide C should be consulted for this information. Additionally, it also does not provide information or guidelines for the use of a sealant in an insulating glass unit edge seal used in a structural sealant glazing application.

The values given in parenthesis are provided for information only. 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.

The destructive procedure stresses the sealant in a way as to cause either cohesive or adhesive failure of the sealant or cohesive failure of the substrate where deficient substrate conditions exist. The nondestructive procedure places strain on the sealant and a stress on the adhesive bond. The Flap Procedure is utilized to evaluate the bond at each substrate, particularly if the substrates on each side of the joint vary. Applicable Products: Weatherproofing sealant joints. Technique 1: Using the probing tool, the center of the sealant bead is depressed to create an elongation strain on the sealant joint. The depth of the depression is recorded as a percentage of the width of the bead.
