4.1 This non-destructive test method contains procedures and equipment requirements to quantitatively determine the surface penetration of water at a single location on a masonry wall. It is not designed to determine the overall water penetration and leakage of a masonry system. 4.2 Excessive water penetration of masonry may degrade masonry wall performance with respect to thermal conductivity, durability, efflorescence, staining, corrosion of embedded metal items, and water leakage. 4.3 This test may be used to evaluate masonry walls in-situ or for field mock-up testing. Common applications of this method have been comparison of water penetration rates of walls before and after repairs, and testing the efficacy of coatings. Alternative procedures are also provided to simulate the effect of local climatology on water penetration of masonry wall surfaces. 4.4 The outer surface of all masonry walls will experience water penetration when subjected to wind-driven rain. The resistance to water penetration is dependent on materials, workmanship, design, and maintenance. Some wall types accommodate large volumes of water penetration, without deleterious effects, through the presence of properly designed and installed drainage systems including flashing and weep holes. Use of this standard without consideration of the overall wall system may lead to incorrect conclusions regarding performance. 4.5 It is the intent of this standard that a sheet of water be developed and maintained on the wall surface during testing. In some cases, due to the surface texture of the masonry, the application of a coating, or other factors, a sheet of water will not consistently form. In those cases, results of this test method will likely be inaccurate. 4.6 This test method is similar to but distinct from the laboratory Test Method E514/E514M. This field test method is designed to test in-situ walls. E514/E514M laboratory test method is designed to test laboratory wall specimens. This test method determines water penetration of the masonry at its surface. Test Method E514/E514M measures the water that has penetrated into and through the masonry specimen and is collected. Results from Test Method C1601 and Test Method E514/E514M are not the same. 1.1 This test method covers the field determination of water penetration of a masonry wall surface under specific water flow rate and air pressure conditions. This test is intended for use on any masonry wall surface that can be properly instrumented and tested within the requirements of this standard. This test method is not identical to and the results are not the same as laboratory standard Test Method E514/E514M. Test Method E514/E514M measures through-wall water penetration, whereas this test method only measures surface water penetration. 1.2 The values stated in inch-pound units are to be regarded as standard.

5.1 The old saying “A chain is only as strong as its weakest link” is very applicable to a SSG system. In reality, a SSG system, to be successful, must establish and maintain a chain of adhesion. For example, a factory applied finish must adhere adequately to a metal framing member, a structural glazing sealant to that metal finish, that structural glazing sealant to a reflective coating on a glass lite, and lastly, that reflective coating to a glass surface. This guide will assist in the identification and development of, among others, performance criteria, test methods, and industry practices that should be implemented to obtain the required structural glazing sealant adhesion and compatibility with other system components. 5.2 Although this guide has been arranged to permit easy access to specific areas of interest, it is highly recommended that the entire guide is read and understood before establishing the requirements for a particular SSG system. 5.3 This guide should not be the only criteria upon which the design and installation of a SSG system is based. The information herein is provided to assist in the development of a specific program with a goal of achieving a successful SSG system installation. Information and guidelines are provided for the evaluation, design, installation, and maintenance of a SSG system and many of its various components. Considering the range of properties of structural glazing silicone sealants, as well as the many types of framing system designs, material combinations that can be used, various material finishes, and the many types and varieties of accessories, the information contained herein is general in nature. 5.4 Generally, the design, fabrication, and installation of a SSG system requires more technical knowledge and experience then is required for a conventionally glazed window or curtain wall system. To ensure the success of a SSG system, it is important that suppliers, fabricators, and installers of materials and components have a sound knowledge of SSG system requirements and become involved in the design and planning for each application. Suppliers of, among others, sealants, framing finishes, glazing materials and components, and various accessories should review and agree with the developed SSG system plans, requirements, and quality control program. 5.5 The results of not planning for and implementing quality control programs during at least the design, testing, fabrication, and installation phases of a SSG system's development can result in less than desirable results, which can include nuisance air or water leakage or catastrophic failure where life safety of the public can be at risk (1, 2).8 1.1 Structural sealant glazing, hereinafter referred to as SSG, is an application where a sealant not only can function as a barrier against the passage of air and water through a building envelope, but also primarily provides structural support and attachment of glazing or other components to a window, curtain wall, or other framing system. 1.2 This guide prov......

4.1 This test method provides information that aids in evaluating the effect of four principal variables: materials, coatings, wall design, and workmanship. 4.2 Water penetration and leakage through masonry is significantly affected by air pressure in the test chamber. Data from tests made at different pressures are not comparable. 4.3 The performance of a masonry wall is a function of materials, construction, wall design, and maintenance. In service the performance will also depend on the rigidity of supporting structure and on the resistance of components to deterioration by various causes, such as corrosion, vibration, thermal expansion and contraction, curing, and others. It is impossible to simulate the complex conditions encountered in service, such as variations in wind velocity, negative pressure, and lateral or upward moving air and water. Factors such as location, exposure, and wall openings should be considered. 4.4 Given the complexity of variables noted above, this test method establishes comparative behavior between various masonry wall constructions in a given laboratory. 4.5 Even when a single laboratory tests the same wall design utilizing the same wall materials and the same construction practices, variables such as the level of skill of the mason building the specimen, the temperature and humidity in the laboratory at the time of construction, curing of the specimen, the moisture contents of the materials used to build the specimen, and even the use or lack of use of a lime and water wash on the back of the specimen can affect the results of the test making reliable comparisons dubious. For these reasons and the multi-variables listed in 4.1, 4.2, and 4.3, a meaningful, useful, absolute wall leakage rating standard is impractical and discouraged. 4.6 This test method is similar to but distinct from field Test Method C1601. This laboratory test method is designed to test laboratory fabricated wall specimens. Field Test Method C1601 is designed to test in-situ walls. This test method measures the water that has penetrated into and through the masonry specimen and is collected. Test Method C1601 determines water penetration of the masonry at its surface. Results from Test Method C1601 and Test Method E514/E514M are not the same. 1.1 This laboratory test method2 provides a procedure for determining the resistance to water penetration and leakage through unit masonry subjected to wind-driven rain. This test method is not identical to and the results are not the same as field standard Test Method C1601. This test method measures through-wall water penetration, whereas Test Method C1601 only measures surface water penetration. 1.2 The values stated in either SI units or......

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 eff......

This European Standard specifies a method for determining the resistance to peeling of joints between two adjacent sheets of the same plastic or rubber sheets for waterproofing. This test method will be used mainly for testing the joints in mechanically fastened plastic or rubber sheets for waterproofing. The peel strength characterises the optimum joint strength which can be reached for a membrane and a joint technique under laboratory conditions. On roofs the joint strength could be clearly reduced due to the non-optimal conditions (e. g. pressure, temperature, humidity, pollution, workmanship). The requirement for the joint technique at the site is to ensure a permanently tight joint.
