5.1 In structural sealant glazing systems, the sealant functions as the structural adhesive and may also function as the primary weather seal. As the structural adhesive, the integrity of the adhesive bond is critical.5.2 Changes in color and adhesion after exposure are two of the criteria that can be used to determine the compatibility of the system. Experience has shown that accessories that cause loss of adhesion or discoloration in this test method may also cause these occurrences in actual use.1.1 This test method covers a laboratory screening procedure for determining the compatibility of liquid-applied structural sealant glazing sealants when in contact with accessories such as dry glazing gaskets, spacers, shims, and setting blocks after exposure to heat and ultraviolet light.1.2 This test method includes the observation of three parameters as follows:1.2.1 Changes in the color of the sealant,1.2.2 Changes in the adhesion of the sealant to glass, and1.2.3 Changes in the adhesion of the sealant to the accessory being tested.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 1: At this time, no comparable ISO standard exists.1.5 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.

5.1 The guide is to be used by anyone developing bonding or sealing requirements for specifications for manufacturing, maintenance or overhaul. This guide has been designed to be application specific for each bonding or sealing application, and allows the design engineer to rest assured that the product(s) or process(es) selected by the industrial or manufacturing engineer will be compatible with both the part material and the subsequent processes, such as adherend/substrate cleaning and preparation. It allows the industrial or manufacturing engineer to customize the selection of the adhesive or sealant product based on the materials of the parts being bonded or sealed, the conditions required for the subsequent process(es), environmental, cost, and health and safety concerns.1.1 This guide is intended to assist design engineers, manufacturing/industrial engineers, and production managers in selecting the best-fit adhesive/sealant or bonding/sealing process. The guide takes into account environmental pollution prevention and occupational health and safety factors in a selection process.1.2 This guide is not to be considered as a database of acceptable materials. It will guide the engineers and managers through the adhesive/sealant material selection process, calling for engineers to customize their selection based on the bonding or sealing performance requirements for the specified application. A comprehensive selection process will allow for the establishment of a more efficient production process, and may eliminate unnecessary process steps. A total life cycle cost analysis or performance/cost of implementation study is recommended to compare the available alternatives.1.3 This guide is for aerospace and general purpose operations. It is not intended to be used for automotive, carpet, construction, electronics, medical/dental, optical, or structural and nonstructural wood applications. Note that this guide is not specifically for these applications, but the general methodology may be used in the selection process for these applications.1.4 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.

1.1 This specification covers the types, grades, and physical properties of aerosol polyurethane and aerosol latex foams extruded from pressurized containers and intended for building envelope air barrier sealant applications in building construction.1.2 For specific aerosol foam sealant applications, operational temperature limit criteria shall be as agreed upon between the aerosol sealant manufacturer and the purchaser.1.3 The values in SI units are to be regarded as standard. The values shown in parentheses are for information and approximation only.1.4 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 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.
