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.
1.2 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.
1.3 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.
