C14.07 - 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.

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.

ABSTRACT
This practice covers the standard for sampling of glass bottles, jars, and other containers intended for use in testing mechanical strength, dimensions, and other measurable characteristics. Sampling from a continuous manufacturing process shall be in accordance with a time schedule. When testing for annealing affected characteristics, samples shall be taken from the exit of the lehr (or from packed cases whose continuity in point of time is known). For characteristics not affected by the degree of annealing, quickly cooled samples may be taken ahead of the lehr. Sample may come from the lot as a whole or it may be necessary to sort the lot before sampling. Sorting may be based on style, color, size, manufacturer, or mold designation. Containers packed in cases shall be removed from the lot at random. The minimum number of cases to be selected shall be in accordance with the military standard prescribed herein.
SCOPE
1.1 This practice covers the sampling of glass containers (for example, bottles, jars, and so forth) for performing such tests as mechanical strength, dimensions, and other measurable characteristics, and for visual examination.
