4.1 Guidelines are provided for the use of silicone sealants in protective glazing. Protective glazing incorporates various forms of glazing that are not covered in Guides C1401 and C1193. The requirements for a sealant in protective glazing are similar to the requirements for structural sealant glazing. However, for certain applications, such as missile impact and blast resistant glazing, sealant requirements may be greater. Modes of failure for blast resistant glazing can be different than the modes of failure for missile impact glazing. Of particular concern is the outbound glazing support loading from blast wave negative phase pressure or the dynamic rebound of the glazing, or both.4.2 Many types of protective glazing systems are relatively new and the test methods and standards for protective glazing are continually evolving. Because the demands on a sealant in protective glazing systems are changing, guidelines are necessarily general in many instances.4.3 As a component of a glazing system, the sealant can be a factor in whether a glazing system meets the requirements of a specific test method but other factors such as the frame and glazing type, may be of greater influence.4.4 The designer of a protective glazing system should consult with the various manufacturers of the component materials. The experience and judgment of the glazing system designer working with the sealant manufacturer and other component manufacturers, can ultimately determine whether a specific glazing system will successfully meet a specific test requirement.1.1 This guide covers the use of silicone sealants in protective glazing systems for building construction. Protective glazing includes systems designed for use in applications subject to natural hazards, such as hurricanes, earthquakes, windstorms, impacts from wind-borne debris; and assaults such as burglary, air blasts, forced-entry attacks and ballistic attacks.1.2 While other glazing accessories and components are used in protective glazing, this document specifically describes the use of silicone sealants for protective glazing systems.1.3 This guide provides information useful to design professionals, architects, manufacturers, installers, and others for the design and use of silicone sealants for protective glazing systems.1.4 A silicone sealant is only one component of a glazing system. A glazing system that meets the testing and code requirement for protective glazing must successfully integrate the frame and its anchorage, glass, or other glazing materials, protective film or interlayer and silicone sealant into a high performance system. Compliance with code or other requirements can be determined through physical testing of the glazing system or through computer simulation.1.5 Glazing systems using silicone sealants that have successfully met the test requirements for missile impact and airblast test requirements incorporate the use of silicone sealants specifically formulated, tested, and marketed for this application. Sealants that are commonly used today comply with Specifications C920 and C1184.1.6 This guide does not discuss sealants intended to protect against radioactivity or provide biological containment.1.7 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.1.8 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.1.9 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.

4.1 Materials and devices that function at least in part by adhering to living tissues are finding increasing use in surgical procedures either as adjuncts to sutures and staples, or as frank replacements for those devices in a wide variety of medical procedures. While the nature and magnitude of the forces involved varies greatly with indication and with patient specific circumstances, all uses involve to some extent the ability of the material to resist imposed mechanical forces. Therefore, the mechanical properties of the materials, and in particular the adhesive properties, are important parameters in evaluating their fitness for use. In addition, the mechanical properties of a given adhesive composition can provide a useful means of determining product consistency for quality control or as a means for determining the effects of various surface treatments on the substrate prior to use of the device.4.2 The complexity and variety of individual applications for tissue adhesive devices, even within a single indicated use (surgical procedure, which itself may vary depending on physical site and clinical intention) is such that the results of a single tensile strength test is not suitable for determining allowable design stresses without thorough analysis and understanding of the application, adhesive behaviors, and clinical indications.4.3 This test method may be used for comparing adhesives or bonding processes for susceptibility to fatigue, mode of failure, and environmental changes, but such comparisons must be made with great caution since different adhesives may respond differently to varying conditions.4.4 A correlation of the test method results with actual adhesive performance in live human tissue has not been established.1.1 This test method covers a means for comparison of wound closure strength of tissue adhesives used to help secure the apposition of soft tissue. With the appropriate choice of substrate, it may also be used for purposes of quality control in the manufacture of medical devices used as tissue adhesives.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 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.

4.1 The purpose of this classification system is to provide a method of adequately identifying silicone adhesives and sealants through the use of a line call-out designation.4.2 This classification system was designed to permit the addition of property values for future silicone adhesives and sealants.1.1 This classification covers silicone adhesives and sealants intended for but not limited to sealing and retaining metallic and nonmetallic component assemblies in transportation applications. The materials cure to an elastomeric state by their specified cure system and mechanism.NOTE 1: The classification system may serve many of the needs of industries using silicone materials. This classification is subject to revision, as the need requires; therefore, the latest revision should always be used.1.2 This classification is intended to be a means of classifying silicone materials. It is not intended for engineering design purposes.1.3 It is not the intent of this classification to include pressure-sensitive or hot-melt adhesives.1.4 In all cases in which the provisions of this classification system would conflict with the referenced ASTM standard for a particular method, the latter shall take precedence.1.5 The values stated in SI units are to be regarded as standard.

4.1 Tests conducted in accordance with this practice are used to evaluate the weatherability of construction seals and sealant materials when they are exposed to outdoor weather conditions. The weatherability of seals and sealants in actual outdoor use can be very different depending on the location because of differences in solar radiation, moisture, temperature, pollutants, and other factors. Sealant color may also affect weatherability.4.2 This practice allows for three options: Option 1 – Procedure A in which the effect of movement during weathering is not considered; Option 2 – Procedure B in which specimens are weathered in conjunction with movement based on thermal changes. The applied strain is proportional to a combination of the temperature at the time the equipment is set up and subsequent thermal changes. This option closely mimics the actual movements that occur in many sealant installations, but is less repeatable than the movement in Procedure C; Option 3 – Procedure C in which the strain during weathering is manually applied. This procedure allows for excellent control and repeatability, but is less representative of movement in actual use conditions than the movement in Procedure B. Options 2 and 3 have been added to this practice based on peer reviewed scientific literature demonstrating that applied strain separately and in combination with other weathering stresses causes changes in the weatherability of sealants.4.3 The type, frequency and amount of movement of sealants varies with location and may affect weatherability. It cannot be assumed, therefore, that results from one exposure in a single location will be useful for determining weatherability in a different location. Exposures in several locations with different climates (for example, solar radiation, moisture, temperature, pollutants, biological and other factors) that represent a broad range of anticipated service conditions are recommended.4.4 It is strongly recommended that control materials of similar composition and construction to the test specimens and with known weatherability be exposed along with the test specimens for the purpose of comparing the performance of test materials to the controls. (See 6.2).4.5 The results of short-term exposure tests can provide an indication of relative outdoor performance, but they shall not be used to predict the absolute long-term performance of a seal or sealant material. The results of tests conducted for less than 12 months will depend on the particular season of the year in which they begin.4.6 Because of year-to-year climatatological variations, results from a single exposure test cannot be used to predict the absolute rate at which a seal or sealant degrades. Several years of repeat exposures are needed to determine an average test result for a given location.4.7 Climatic and construction factors can impose cyclic movement upon sealed joints in use. This movement can impact the effects of outdoor weathering and often causes types of failure that are not produced by weathering without movement. Thus, the ability of building joint sealants to withstand temperature-induced movements of compression and expansion is an important property.4.8 Outdoor weathering of specimens in combination with natural or forced cyclic movement during exposure can provide a more realistic assessment of the ability of a seal or sealant to withstand the combined effects of climate and movement encountered by seals and sealants in building construction applications.1.1 This practice describes outdoor exposure procedures to be used as part of a test designed to determine the weatherability of building construction, seals and sealants.NOTE 1: See Practice G24 for Exposures to Daylight Filtered Through Glass.1.2 This practice includes three procedures for outdoor weathering. Procedure A exposes specimens to outdoor weathering without movement. Procedure B and Procedure C are, respectively, continuous natural and periodic manual techniques for subjecting specimens to the combination of cyclic movement and exposure to outdoor weathering.1.3 This practice is limited to the method by which the construction seals or sealants are exposed to outdoor weathering as part of a test program. It refers to the types of evaluations to be performed following the outdoor exposure but does not describe the test methods.1.4 Means of evaluation of the effects of weathering will depend on the intended use of the test material.1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.6 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.1.7 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 This specification is designed to give some indication as to the differences in performance for various cylindrical sealant backings.5.2 Although this specification qualifies a cylindrical sealant backing for use, it does not address the compatibility of the backing with the sealants with which it will make contact. Sealant compatibility should be confirmed by the sealant manufacturer. Compatibility characteristics of sealants in contact with cylindrical sealant backings can be determined by Test Method C1087.AbstractThis standard specification covers the basic requirements for cylindrical sealant backing for use with cold liquid-applied sealants. Cylindrical sealant backings are classified into three types: type C, type O, and type B, composed predominantly of closed cell material, open cell material, and bi-cellular material, respectively. Test methods for cylindrical sealant backing include water absorption, density, outgassing, compression deflection and recovery, and tensile strength. The sealant shall be clean, free of scale, foreign matter, oil, or water.1.1 This specification covers the basic requirements for cylindrical sealant backing to be used with cold liquid applied sealants for use in building seals.1.2 Cylindrical sealant backing serves one or more of the following functions:1.2.1 Limits the amount and depth of sealant applied into a joint,1.2.2 Acts as a bond breaker to allow joint movement without undue stress to the sealant,1.2.3 Provides a form to assist the sealant in developing the proper shape factor, and1.2.4 Acts as a barrier to the flow of sealant through the joint.1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other ASTM committees or other organizations.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.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.

4.1 Staining of a building is an aesthetically undesirable occurrence. This test method evaluates the likelihood of a sealant causing early stain on a porous substrate due to certain chemical exudations from the sealant.4.1.1 This test method may not predict staining caused by such factors as residue run-down or dirt pick-up by a sealant exudate.4.2 This test method is useful to predict potential color changes in the sealant itself after weathering.4.3 This test method measures color change in a sealant and staining of substrate by the sealant under conditions of artificial weathering. See also Test Method D2203, which measures staining by a sealant due to gross exudations from the sealant; it does not subject the sealant to artificial weathering.1.1 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 also is intended to determine whether the sealant itself will change in color when exposed to the weather.1.2 The values stated in SI units are to be regarded as the standard.

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.
