Standard Test Method for Insulating Glass Unit Performance

SIGNIFICANCE AND USE
This test method is intended to provide a means for testing the performance of the sealing system and construction of sealed insulating glass units.
Sealed insulating glass units tested in accordance with this method may be suitable for structurally glazed applications. However, factors such as sealant longevity when exposed to long term ultraviolet light and the structural properties of the sealant must be reviewed for these applications.
Sealed insulating glass units tested in accordance with this method are not intended for continuous exposure to high relative humidity conditions or long-term immersion in water.
SCOPE
1.1 This test method covers procedures for testing the performance of preassembled permanently sealed insulating glass units or insulating glass units with capillary tubes intentionally left open.
1.2 This test method is applicable only to sealed insulating glass units that are constructed with glass.
1.3 This test method is applicable to both double-glazed and triple-glazed insulating glass units. For triple-glazed insulating glass units where both of the outer lites are glass and the inner lite is either glass or a suspended film.
1.4 The unit construction used in this test method contains dimensions that are an essential component of the test. Different types of glass, different glass thicknesses, and different airspace sizes may affect the test results.
1.5 This test method is not applicable to sealed insulating glass units containing a spandrel glass coating due to testing limitations.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Determining Argon Concentration in Sealed Insulating Glass Units using Gas Chromatography

SIGNIFICANCE AND USE
4.1 This test method is intended to provide a means for determining the concentration of fill gases, typically argon, oxygen, and nitrogen gases in individual sealed insulating glass units, which were intended to be filled with a specific concentration of fill gases at the time of manufacture.  
4.2 The fill gases, oxygen and nitrogen, are physically separated by gas chromatography and compared to corresponding components separated under similar conditions from a reference standard mixture or mixtures of known composition. If the carrier gas is the same as the fill gas, then just the oxygen and nitrogen (air contaminate) are separated.  
4.3 The composition of the sample is calculated from the chromatogram by comparing the area under the curve of each component with the area under the curve of the corresponding component on the reference standard chromatogram.  
4.4 It is essential that the person or persons performing this test are very knowledgeable about the principles and techniques of gas chromatography, operation and calibration of gas chromatographs. More information can be found in Practice E355.  
4.5 It takes time for the fill gas to equilibrate in any insulating glass unit. This is particularly important in insulating glass units using a tubular spacer and in units containing interior components such as tubular muntin bars. Performing this test before a unit has equilibrated could result in fill gas concentrations that are measurably different than the actual fill gas concentration.  
4.6 This method may be used to determine the initial fill gas concentration achieved by the filling method, or the fill gas concentration in units that have been in service or that have been subjected to durability tests such as those described in Test Method E2188.  
4.7 This is a destructive test method in that the edge seal of the insulating glass unit is breached in order to obtain a gas sample for analysis by gas chromatography.
SCOPE
1.1 This test method covers procedures for using gas chromatographs to determine the concentration of argon gas in the space between the panes of sealed insulating glass.  
1.2 This test method is not applicable to insulating glass units containing open capillary/breather tubes.  
1.3 The values stated in inch-pound 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, 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.

ASTM C912-17(2022)(Practice)
Standard Practice for Designing a Process for Cleaning Technical Glasses

SIGNIFICANCE AND USE
3.1 Many of the low-silica technical glasses which contain soluble or reactive oxides require processing or involve applications that require cleaning. Very often these cleaning procedures have evolved over several decades and are considered an art. They usually contain numerous steps, some of questionable validity. It is the premise of this practice that cleaning glass can be more scientific. Design of a cleaning procedure should involve (1) a definition of the soil to be removed, (2) an awareness of the constraints imposed by the glass composition, and (3) a rational selection of alternative methods that will remove the soil and leave the glass in a condition suitable for its intended application. This practice provides information to assist in step (3). General references on glass cleaning and on various methods of evaluating cleanliness and associated information has been published.2
SCOPE
1.1 This practice covers information that will permit design of a rational cleaning procedure that can be used with a glass that is somewhat soluble in many aqueous chemical solutions. Typically, this type of glass is used in applications such as optical ware, glass-to-metal seals, low dielectric loss products, glass fibers, infrared transmitting products, and products resistant to metallic vapors.  
1.2 In most cases, this type of glass contains high concentrations of oxides that tend to react with a number of aqueous chemicals. Such oxides include B2O3, Al2O3, R2O, RO, La2O3, ZnO, PbO, P2O5, and Fe2O3. The more conventional high-silica glasses are usually more chemically resistant, but the cleaning principles outlined here also apply to them.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 4 and Table 1.  
1.4 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.

Standard Test Method for Assignment of the Glass Transition Temperature by Thermomechanical Analysis

SIGNIFICANCE AND USE
5.1 The glass transition is dependent on the thermal history of the material to be tested. For amorphous and semicrystalline materials the assignment of the glass transition temperature may lead to important information about thermal history, processing conditions, stability, progress of chemical reactions, and mechanical and electrical behavior.  
5.2 Thermomechanical analysis provides a rapid means of detecting changes in hardness or linear expansion associated with the glass transition.  
5.3 This test method is useful for research and development, quality control, and specification acceptance.
SCOPE
1.1 This test method describes procedures for the assignment of the glass transition temperature of materials on heating using thermomechanical measurements under compression experimental conditions.  
1.2 This test method is applicable to amorphous or to partially crystalline materials that are sufficiently rigid below the glass transition to inhibit indentation by the sensing probe.  
1.3 The normal operating temperature range is from −100 °C to 600 °C. This temperature range may be extended depending upon the instrumentation used.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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. Specific precautionary statements are given in Section 7.  
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.

Standard Test Method for Measurement of Viscosity of Glass Between 104 Pa·s and 108 Pa·s by Viscous Compression of a Solid Right Cylinder [Metric]

SIGNIFICANCE AND USE
4.1 This test method is well suited for measuring the viscosity of glasses between the range within which rotational viscometry (see Practice C965) is useful and the range within which beam bending viscometry is useful (see Test Method C1350M). It can be used to determine the viscosity/temperature curve in the region near the softening point (see Test Method C338). This test method is useful for providing information related to the behavior of glass as it is formed into an object of commerce, and in research and development.
SCOPE
1.1 This test method covers the determination of the viscosity of glass from 104 Pa·s to 108 Pa·s by measuring the rate of viscous compression of a small, solid cylinder.2  
1.2 The values stated in SI units are to be regarded as the standard.

Standard Practice for Weathering and Evaluation of Laminated Glass

SIGNIFICANCE AND USE
4.1 Tests conducted in accordance with this practice are used to evaluate the stability of laminated glazing materials when they are exposed outdoors or used indoors. The relative durability of glazing in outdoor use can be very different depending on the location of the exposure because of differences in ultraviolet (UV) radiation, time of wetness, temperature, pollutants, and other factors. It cannot be assumed, therefore, that results from one exposure in a single location will be useful for determining relative durability in a different location. When comparing exposure results, at a minimum, the locations of exposure are to be as similar as possible with regard to critical factors such as the amount and rate of solar radiation deposited on the specimens, temperature and humidity levels during exposure. Exposures in several locations with different climates that represent a broad range of anticipated service conditions may be necessary.  
4.2 Because of year-to-year climatological variations, results from a single exposure test cannot be used to predict the absolute rate at which a material degrades. Several years of repeat exposures are needed to get an average test result for a given location.  
4.3 The results of short-term natural and accelerated exposure tests can provide an indication of relative outdoor performance, but they should not be used to predict the absolute long-term performance of a material. The results of tests conducted under natural exposure for less than twelve months will depend on the particular season of the year in which they begin.
SCOPE
1.1 This practice is intended to cover procedures for the exposure of laminated glass materials to natural and accelerated weather.  
1.2 This practice is limited to the method by which the material is to be exposed and the general procedure to be followed. It is intended for use with finished articles of commerce as well as with all sizes and shapes of test specimens.  
1.3 Means of evaluation of the effects of weathering will depend on the intended use for the test material.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
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.

Standard Test Method for Measuring Optical Retardation and Analyzing Stress in Glass

SIGNIFICANCE AND USE
4.1 The performance of glass products may be affected by presence of residual stresses due to process, differential thermal expansion between fused components, and by inclusions. This test method provides means of quantitative evaluation of stresses.
SCOPE
1.1 This test method covers the analysis of stress in glass by means of a polarimeter based on the principles developed by Jessop and Friedel (1, 2).2 Stress is evaluated as a function of optical retardation, that is expressed as the angle of rotation of an analyzing polarizer that causes extinction in the glass.  
1.2 There is no known ISO equivalent to this standard.

4.2 It should be recognized that measurement of surface fragments, especially from float glass samples, can result in refractive index values which are different than the refractive index values of fragments from the interior of (for example, bulk) the same broken glass source (5).  
4.3 The precision of this test method shall be established in each laboratory that employs it as part of the validation protocol (see Section 9).  
4.4 It should be recognized that this technique measures the refractive index of the glass at the match point temperature, which will be higher than ambient temperature, and thus, may give different  values from those obtained by other methods, which measure the refractive index at room temperature.
SCOPE
1.1 This test method covers a procedure for measuring and comparing the refractive index (η) at a fixed wavelength (λ) and temperature (T) ( ) of glass from known sources to recovered fragments from a questioned source.  
1.2 This test method does not include the measurement of optical dispersion or the measurement of refractive index ( ) at any other wavelength other than the Sodium D line ( ). This method employs a narrow band pass filter at 589 nm, but other filters could be employed using the described method, allowing the  to be determined at other wavelengths, and therefore, also allowing for the dispersion value to be calculated.  
1.3 Alternative methods for the determination of  are listed in Refs (1-5).2  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard cannot replace knowledge, skills, or abilities acquired through education, training, and experience and is to be used in conjunction with professional judgment by individuals with such discipline-specific knowledge, skills, and abilities.  
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.

ASTM
ASTM C1350M-96(2019)(Test Method)
Standard Test Method for Measurement of Viscosity of Glass Between Softening Point and Annealing Range (Approximately 108 Pa·s to Approximately 1013 Pa·s) by Beam Bending (Metric)

SIGNIFICANCE AND USE
4.1 This test method is well suited for measuring the viscosity of glasses in ranges higher than those covered by parallel plate (see Test Method C1351M) and rotational viscometry (see Practice C965) methods. This test method is useful for providing information related to the behavior of glass after it has been formed into an object of commerce and in research and development.
SCOPE
1.1 This test method covers the determination of glass viscosity from approximately 108 Pa·s to approximately 1013 Pa·s by measuring the rate of viscous bending of a simply loaded glass beam.2 Due to the thermal history of the glass, the viscosity may not represent conditions of thermal equilibrium at the high end of the measured viscosity range. Measurements carried out over extended periods of time at any temperature or thermal preconditioning will minimize these effects by allowing the glass to approach equilibrium structural conditions. Conversely, the method also may be used in experimental programs that focus on nonequilibrium conditions.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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.
