Standard Test Method for Thermal Shock Resistance of Glass Containers

Standard Test Method for Thermal Shock Resistance of Glass Containers

ABSTRACT
This test method covers the determination of the relative thermal shock resistance of commercial bottles and jars and is intended to apply to all types of glass containers that are required to withstand sudden changes in temperature in service. The test apparatus consists essentially of a basket for holding the glassware upright, a hot water tank, a cold water tank, and a timed means for immersing and transferring the basket from the hot to the cold bath. Indicating controllers or dial thermometers should be used to maintain the temperatures of the baths. Test procedures included in this specification include pass tests, progressive tests to a predetermined percent of breakage, total progressive tests, and high-level tests.
SCOPE
1.1 This test method covers the determination of the relative resistance of commercial glass containers (bottles and jars) to thermal shock and is intended to apply to all types of glass containers that are required to withstand sudden temperature changes (thermal shock) in service such as in washing, pasteurization, or hot pack processes, or in being transferred from a warm to a colder medium or vice versa.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.

Standard Guide for Choosing a Method for Determining the Index of Refraction and Dispersion of Glass

SIGNIFICANCE AND USE
4.1 Measurement—The refractive index at any wavelength of a piece of homogeneous glass is a function, primarily, of its composition, and secondarily, of its state of annealing. The index of a glass can be altered over a range of up to 1×10-4 (that is, 1 in the fourth decimal place) by the changing of an annealing schedule. This is a critical consideration for optical glasses, that is, glasses intended for use in high performance optical instruments where the required value of an index can be as exact as 1×10-6. Compensation for minor variations of composition are made by controlled rates of annealing for such optical glasses; therefore, the ability to measure index to six decimal places can be a necessity; however, for most commercial and experimental glasses, standard annealing schedules appropriate to each are used to limit internal stress and less rigorous methods of test for refractive index are usually adequate. The refractive indices of glass ophthalmic lens pressings are held to 5×10-4 because the tools used for generating the figures of ophthalmic lenses are made to produce curvatures that are related to specific indices of refraction of the lens materials.  
4.2 Dispersion—Dispersion-values aid optical designers in their selection of glasses (Note 1). Each relative partial dispersion-number is calculated for a particular set of three wavelengths, and several such numbers, representing different parts of the spectrum might be used when designing more complex optical systems. For most glasses, dispersion increases with increasing refractive index. For the purposes of this standard, it is sufficient to describe only two reciprocal relative partial dispersions that are commonly used for characterizing glasses. The longest established practice has been to cite the Abbe-number (or Abbe ν-value), calculated by:
where vD is defined in 3.2 and nD, nF, and nC are the indices of refraction at the emission lines defined in 3.2.  
4.2.1 Some modern usage sp...
SCOPE
1.1 This guide identifies and describes seven test methods for measuring the index of refraction of glass, with comments relevant to their uses such that an appropriate choice of method can be made. Four additional methods are mentioned by name, and brief descriptive information is given in Annex A1. The choice of a test method will depend upon the accuracy required, the nature of the test specimen that can be provided, the instrumentation available, and (perhaps) the time required for, or the cost of, the analysis. Refractive index is a function of the wavelength of light; therefore, its measurement is made with narrow-bandwidth light. Dispersion is the physical phenomenon of the variation of refractive index with wavelength. The nature of the test-specimen refers to its size, form, and quality of finish, as described in each of the methods herein. The test methods described are mostly for the visible range of wavelengths (approximately 400 μm to 780 μm); however, some methods can be extended to the ultraviolet and near infrared, using radiation detectors other than the human eye.  
1.1.1 List of test methods included in this guide:
1.1.1.1 Becke line (method of central illumination),
1.1.1.2 Apparent depth of microscope focus (the method of the Duc de Chaulnes),
1.1.1.3 Critical Angle Refractometers (Abbe type and Pulfrich type),

Standard Test Methods for Polariscopic Examination of Glass Containers

SIGNIFICANCE AND USE
4.1 These two test methods are provided for evaluating the quality of annealing. These test methods can be used in the quality control of glass containers or other products made of similar glass compositions, where the degree of annealing must be verified to ensure quality products. These test methods apply to glass containers manufactured from commercial soda-lime-silica glass compositions.
SCOPE
1.1 These test methods describe the determination of relative optical retardation associated with the state of anneal of glass containers. Two alternative test methods are covered as follows:    
Sections  
Test Method A—Comparison with Reference Standards
Using a Polariscope  
6 – 9  
Test Method B—Determination with Polarimeter  
10 – 12  
1.2 Test Method A is useful in determining retardations less than 150 nm, while Test Method B is useful in determining retardations less than 565 nm.  
Note 1: The apparent temper number as determined by these test methods depends primarily on (1) the magnitude and distribution of the residual stress in the glass, (2) the thickness of the glass (optical path length at the point of grading), and (3) the composition of the glass. For all usual soda-lime silica bottle glass compositions, the effect of the composition is negligible. In an examination of the bottom of a container, the thickness of glass may be taken into account by use of the following formula, which defines a real temper number, TR, in terms of the apparent temper number, TA, and the bottom thickness, t:
This thickness should be measured at the location of the maximum apparent retardation. Interpretation of either real or apparent temper number requires practical experience with the particular ware being evaluated.  
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.  
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.

Standard Test Methods for Resistance of Glass Containers to Chemical Attack

SIGNIFICANCE AND USE
3.1 The solubility of glass in contact with food, beverages, or pharmaceutical products is an important consideration for the safe packaging and storage of such materials. Autoclave conditions are specified since sterilization is often employed for the packaging of the product. It also represents one of the most extreme conditions, particularly of temperature, that containers will ordinarily experience. Any of the three test methods described may be used to establish specifications for conformity to standard values, either as specified by a customer, an agency, or “The United States Pharmacopeia:”  
3.1.1 Test Method B-A  is intended particularly for testing glass containers primarily destined for containment of products with a pH under 5.  
3.1.2 Test Method B-W  is intended particularly for testing glass containers to be used for products with a pH of 5.0 or over.  
3.1.3 Test Method P-W  is a hydrolytic autoclave test primarily intended for evaluating samples from untreated glass containers. It is often useful for testing the resistance of containers of too small capacity to permit measurements of solubility on the unbroken article by the B-W test method. Yielding the water resistance of the bulk glass, it can also be used in conjunction with the B-W test method to distinguish whether the internal surface of a container has been treated to improve its durability.  
3.2 All three test methods are suitable for specification acceptance.
SCOPE
1.1 These test methods cover the evaluation of the resistance of glass containers to chemical attack. Three test methods are presented, as follows:  
1.1.1 Test Method B-A  covers autoclave tests at 121 °C on bottles partially filled with dilute acid as the attacking medium.  
1.1.2 Test Method B-W  covers autoclave tests at 121 °C on bottles partially filled with distilled water as the attacking medium.  
1.1.3 Test Method P-W  covers autoclave tests at 121 °C on powdered samples with pure water as the attacking medium.  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
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.

Standard Practice for Instrumental Transmittance Measurement of Color for Flat Glass, Coated and Uncoated

SIGNIFICANCE AND USE
4.1 Color measurement quantifies the transmitted color for glass. The user defines an acceptable range of color appropriate for the end use. A typical quality concern for transmittance color measurement of glass products is verification of lot-to-lot color consistency for end-user acceptance.  
4.2 If the transmitted color of a glass product is consistent from lot-to-lot and within agreed supplier-buyer acceptance criteria, the product’s color is expected to be consistent and acceptable for end-use.
SCOPE
1.1 This practice provides guidelines for the instrumental transmittance measurement of the color of coated and uncoated transparent glass. (See Terminology E284.)  
1.2 The practice specifically excludes fluorescent and iridescent samples.  
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.

Standard Test Method for Bake and Boil Testing of Laminated Glass

SIGNIFICANCE AND USE
5.1 It is generally recognized that excess moisture and air within an interlayer will cause bubble formation in a laminate when exposed to heat or UV radiation, or both. These may be caused by initial moisture and air in the interlayer and be generated by thermal exposure. The purpose of this test method is to measure quantitatively the laminate stability under controlled conditions, specifically in relation to the formation of bubbles in the body of the laminate.  
5.2 Subjecting the laminated glazing to extended heat at a controlled temperature and time provides the excess moisture and air which are forced into the interlayer during processing to surface as bubbles. This occurs only if there are excess moisture and air trapped in between the glass. Therefore, making these thermal tests efficient to determine proper de-airing of laminated glass products.  
5.3 This test method provides a means to visually determine if discoloration has or is occurring and serves as a pass/fail test for some aspects of lamination quality.  
5.4 This test method can be performed after natural or accelerated exposure to determine if there are changes to the polymer such as the stability with high temperature which is useful for understanding the visual stability of installed glazing.  
5.5 This test method does not provide an indication of laminated glass capability for impact resistance, glass shard retention on breakage or edge stability of laminated glass.
SCOPE
1.1 The purpose of this test method is to measure quantitatively the laminate stability under controlled conditions, specifically in relation to the formation of bubbles in a laminate with heat exposure.  
1.2 This test method can be performed on laminates which have been exposed to weathering or as manufactured samples to determine the amount of excess air dissolved in the interlayer.  
1.3 This test method determines the stability of laminated glass when subjected to high heat environments.  
1.4 This test method outlines a procedure to be used on laminated glass with two or more layers of glass bonded by an interlayer.  
1.5 This test method covers visual rating of tested specimens.  
1.6 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.  
1.7 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.

Standard Test Method for Young's Modulus, Shear Modulus, and Poisson's Ratio for Glass and Glass-Ceramics by Resonance

SIGNIFICANCE AND USE
4.1 This test system has advantages in certain respects over the use of static loading systems in the measurement of glass and glass-ceramics:  
4.1.1 Only minute stresses are applied to the specimen, thus minimizing the possibility of fracture.  
4.1.2 The period of time during which stress is applied and removed is of the order of hundreds of microseconds, making it feasible to perform measurements at temperatures where delayed elastic and creep effects proceed on a much-shortened time scale, as in the transformation range of glass, for instance.  
4.2 The test is suitable for detecting whether a material meets specifications, if cognizance is given to one important fact: glass and glass-ceramic materials are sensitive to thermal history. Therefore the thermal history of a test specimen must be known before the moduli can be considered in terms of specified values. Material specifications should include a specific thermal treatment for all test specimens.
SCOPE
1.1 This test method covers the determination of the elastic properties of glass and glass-ceramic materials. Specimens of these materials possess specific mechanical resonance frequencies which are defined by the elastic moduli, density, and geometry of the test specimen. Therefore the elastic properties of a material can be computed if the geometry, density, and mechanical resonance frequencies of a suitable test specimen of that material can be measured. Young's modulus is determined using the resonance frequency in the flexural mode of vibration. The shear modulus, or modulus of rigidity, is found using torsional resonance vibrations. Young's modulus and shear modulus are used to compute Poisson's ratio, the factor of lateral contraction.  
1.2 All glass and glass-ceramic materials that are elastic, homogeneous, and isotropic may be tested by this test method.2 The test method is not satisfactory for specimens that have cracks or voids that represent inhomogeneities in the material; neither is it satisfactory when these materials cannot be prepared in a suitable geometry. Non-glass and glass-ceramic materials should reference Test Method E1875 for non-material specific methodology to determine resonance frequencies and elastic properties by sonic resonance.
Note 1: Elastic here means that an application of stress within the elastic limit of that material making up the body being stressed will cause an instantaneous and uniform deformation, which will cease upon removal of the stress, with the body returning instantly to its original size and shape without an energy loss. Glass and glass-ceramic materials conform to this definition well enough that this test is meaningful.
Note 2: Isotropic means that the elastic properties are the same in all directions in the material. Glass is isotropic and glass-ceramics are usually so on a macroscopic scale, because of random distribution and orientation of crystallites.  
1.3 A cryogenic cabinet and high-temperature furnace are described for measuring the elastic moduli as a function of temperature from –195 to 1200 °C.  
1.4 Modification of the test for use in quality control is possible. A range of acceptable resonance frequencies is determined for a piece with a particular geometry and density. Any specimen with a frequency response falling outside this frequency range is rejected. The actual modulus of each piece need not be determined as long as the limits of the selected frequency range are known to include the resonance frequency that the piece must possess if its geometry and density are within specified tolerances.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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...

Standard Test Method for Thermal Shock Resistance of Glass Containers

ABSTRACT
This test method covers the determination of the relative thermal shock resistance of commercial bottles and jars and is intended to apply to all types of glass containers that are required to withstand sudden changes in temperature in service. The test apparatus consists essentially of a basket for holding the glassware upright, a hot water tank, a cold water tank, and a timed means for immersing and transferring the basket from the hot to the cold bath. Indicating controllers or dial thermometers should be used to maintain the temperatures of the baths. Test procedures included in this specification include pass tests, progressive tests to a predetermined percent of breakage, total progressive tests, and high-level tests.
SCOPE
1.1 This test method covers the determination of the relative resistance of commercial glass containers (bottles and jars) to thermal shock and is intended to apply to all types of glass containers that are required to withstand sudden temperature changes (thermal shock) in service such as in washing, pasteurization, or hot pack processes, or in being transferred from a warm to a colder medium or vice versa.

Standard Specification for Heat-Strengthened and Fully Tempered Flat Glass

ABSTRACT
This specification covers heat-treated flat glass - kind HS, kind FT coated and uncoated glass used in general building construction. Glass furnished under this specification shall be of the following conditions: condition A - uncoated surfaces, condition B - spandrel glass, one surface ceramic coated, and condition C - other coated glass. Flat glass furnished under this specification shall be of the following kinds: kind HS - heat-strengthened glass shall be flat glass, either transparent or patterned, in accordance with the applicable requirements, and kind FT - fully tempered glass shall be flat glass, either transparent or patterned in accordance with the applicable requirements. All fabrication, such as cutting to overall dimensions, edgework, drilled holes, notching, grinding, sandblasting, and etching, shall be performed before strengthening or tempering and shall be as specified. Requirements for fittings and hardware shall be as specified. In heat-strengthened and fully tempered glass, a strain pattern, which is not normally visible, may become visible under certain light conditions. The support system and the amount of glass deflection for a given set of wind-load conditions must be considered for design purposes. Heat-treated flat glass cannot be cut after tempering. Heat-treated glass can be furnished with holes, notches, cutouts, and bevels. The expansion fit and porosity of the ceramic coating shall be tested to meet the requirements prescribed. Specimens for evaluation of resistance to alkali and acid shall be prepared and tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers the requirements for monolithic flat heat-strengthened and fully tempered coated and uncoated glass produced on a horizontal tempering system used in general building construction and other applications.  
1.2 This specification does not address bent glass, or heat-strengthened or fully tempered glass manufactured on a vertical tempering system.  
1.3 The dimensional values stated in SI units are to be regarded as the standard. The units given in parentheses are for information only.
