5.1 Post dispensing volumetric expansion factor F indicates the ratio of the fully cured foam sealant volume and the initially dispensed foam sealant volume. For example, if the expansion factor F were 2, the fully cured foam would double its initial volume; therefore, one should fill 50 % of the cavity uniformly to anticipate the full coverage upon curing.5.2 Post dispensing volumetric expansion factor F does not predict the performance capability of the foam sealants of the suitability for the intended applications.5.3 This test method is intended to lend guidance in product selection as related to the post dispensing expansion characteristics of the aerosol foam sealants.5.4 This test method recognizes that the results are reflective of controlled laboratory conditions. Post dispensing expansion in field applications may vary according to temperature, humidity, and surfaces that the aerosol foam sealants are in contact with.1.1 This test method measures the volumetric expansion of aerosol foam sealants after dispensing.1.2 This test method provides a means for estimating the quantity of initial material required to dispense in order to fill a cavity.1.3 Aerosol foam sealants are used for a variety of applications intended to reduce airflow through the building envelope.1.4 This test method applies to two types of single component aerosol foam sealants: polyurethane and latex.1.5 There are no other known standard test methods to measure aerosol foam sealants post dispensing expansion.1.6 Values are reported in SI units only. Certain apparatus and supply items are referenced in inch-pound units for purchasing purposes.1.7 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.1.8 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.

7.1 Not all sealants meeting this specification should be presumed to be suitable for all applications and all substrates. This specification assists in selecting sealants that meet certain minimum standards of performance.7.2 This specification does not evaluate the adhesion of the secondary sealant to the IG unit spacer. Adhesion of the secondary sealant to the spacer is generally considered necessary for the successful performance of the IG unit edge seal.7.3 When specifying a sealant using this specification, it is essential that the applicable type and use also be included in the requirements. This will ensure that the proper sealant is provided for the intended use.7.4 IG units qualified by this specification shall have a low moisture vapor transmission sealant for a primary seal and a structural silicone sealant for a secondary seal.7.5 This specification does not address appropriate sealant stiffness since the appropriate stiffness is a function of the particular insulating glass system in which the sealant is used (that is, varies with spacer, shape and set back, and sealant configuration). Test Method C1265 can assist in evaluating these aspects of the sealant in a particular IG system.AbstractThis specification covers cold, liquid-applied, single or multi-component, chemically curing, elastomeric secondary edge sealants for sealed structurally glazed insulating glass units. Only the minimum acceptable test requirements for and the durability of these materials are described by this specification. A sealant that qualifies under this specification is classified into two types according to the number of components and into two uses according to application. Sealants should conform to the required values of extrudability, rheology, hardness, heat aging, weight loss, cracking, chalking, durability, tensile strength, and minimum shelf life.1.1 This specification describes the properties of cold, liquid-applied, single or multi-component, chemically curing, elastomeric sealants used as the secondary seal of sealed insulating glass units, hereinafter referred to as the “sealant” (see Fig. 1). 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). Typical designs and considerations can be found in Guide C1249. Presently only certain silicone sealants are recognized as having the necessary durability for use as secondary sealant in IG units in SSG applications.FIG. 1 Cutaway Section of IG Unit Edge Seal1.2 This specification does not describe all of the necessary properties of the sealant. Only those properties for which there are ASTM test methods and industry-agreed-upon minimum acceptable test requirements are described by this specification. Additional properties will be added as ASTM test methods for these properties become available.1.3 This specification only addresses the durability of the secondary edge sealants for structurally glazed insulating glass units. Durability of sealed insulating glass units can be found in specifications and guides that reside within ASTM Committee E06.1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information purposes only.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.

5.1 Preformed tape sealants are tacky, deformable solids that are used under compression between two substrates in various sealing applications. These tapes are usually supplied in roll form with a release paper interlayer. When the roll is unwound and the release paper is removed from the preformed tape sealant, there should be no transfer of the preformed tape sealant to the release paper, nor any residue left on the paper. These methods will give a qualitative indication of whether or not the release paper can be removed cleanly from a preformed tape sealant after a controlled exposure period.5.2 Alternative procedures are listed because some preformed tape sealants are normally used under field conditions where elevated temperatures can be encountered, while other preformed tape sealants are normally used under more controlled environments in “assembly line” operations.1.1 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.1.2 The values stated in metric (SI) units are to be regarded as the standard.

5.1 The failure of a building sealant in an active joint is usually manifested by cohesive failure in the sealant or adhesive failure between the sealant and the substrate, or both. The method described in this test method relates only to the performance of the sealant when properly installed with recommended primers, and does not evaluate sealant failures caused by improper joint design, excessive joint movement, improper application practices, and other factors known to cause sealant failure in buildings and building areas.1.1 This test method is an accelerated laboratory procedure for evaluating the performance of a building sealant in a test configuration that is subjected to water immersion, cyclic movement, and temperature change.31.2 The values stated in inch-pound units are to be regarded as standard.

5.1 Shrinkage of a sealant, after application in a building joint, is caused by loss of volatile components from the sealant. This loss results in a decrease in volume and, hence, a change in the sealant's shape. This change in shape, in some applications, should be taken into consideration for acceptable joint appearance and geometry.5.2 The shrinkage value obtained by this test method helps predict the appearance and geometry of the cured sealant in a building joint and is helpful in determining the amount and type of tooling to be done during installation of the sealant.5.3 Latex sealants cure primarily through water evaporation. They may also contain small amounts of other volatile components. However, in this test method all volatiles are treated as water. This assumption still provides a meaningful shrinkage value since the small quantities of other volatiles and their differences in density from that of water do not significantly affect the usefulness of the result obtained.1.1 This test method covers a laboratory procedure for determining volume shrinkage, which occurs during cure, of a latex sealant.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

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 and cohesive properties, are important parameters in evaluating their fitness for use. In addition, the mechanical properties of a given sealant 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 sealant, even within a single indicated use (surgical procedure), is such that the results of a burst test are not suitable for determining allowable design stresses without thorough analysis and understanding of the application and sealant behaviors.4.3 This test method may be used for comparing sealants for susceptibility to environmental changes, but such comparisons must be made with great caution since different sealants may respond differently to varying conditions.4.4 As the true sealant strength is strongly dependent on the strength of the sealant/substrate interface, the selection of a proper test substrate is critical. Care must be taken when extrapolating in vitro test results to in vivo expectations. In vitro sealant optimization may not translate to expected in vivo performance due to differences in substrate surface, strength, and elasticity.1.1 This test method provides a means for comparison of the burst or rupture strength of sealants on soft tissue. This test method can be used as a clinically relevant model for quality assurance, development, and comparative testing of different adhesives or adherends.1.2 This test method measures only burst strength or “cohesive strength” of an adhesive/adherend system, and not the adhesive strength.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

5.1 It is difficult to establish a precise correlation between laboratory accelerated and natural weathering because of (1) geographical climatic variations, local weather variation from normal, and local pollutants and (2) the fact that the acceleration factor is material dependent, varying with the type of material as well as its formulation. This test method is used to determine the resistance of a sealant to laboratory accelerated weathering and, if a control material with known outdoor weathering performance is used, the relative weathering performance of the sealant against that of the control material.5.2 This test method is conducted using aluminum channels. Other substrate materials may show different results.1.1 This test method includes two laboratory accelerated exposure procedures for predicting the effects of ultraviolet or ultraviolet/visible radiation, heat, and moisture on color, chalking, cracking, and adhesion of solvent-release sealants.1.2 The values stated in SI units are to be regarded as the standard.
