1.1 This practice describes the procedures for testing loaded shipping containers that would be sold to the United States government. The following tests are performed to measure the ability of the shipping container to protect the contents from the environment, shock, and vibration during wartime conditions. This practice is not intended to supplant material specifications or existing pre-shipment test procedures. The suitability of this practice for use with hazardous materials has not been determined. 1.2 The procedures covered in this practice are suitable for all types of laboratory apparatus including reusable and disposable macro and micro products. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This specification covers a limit for thermal residual stress in reusable annealed glass laboratory apparatus as determined by prescribed photoelastic measurement procedures. 1.2 In broad classification, the laboratory glassware items covered by this specification, but not limited to, are: beakers Imhoff cones bottles, aspirator impingers bottles, dropping jars, battery bottles, gas washing jars, bell bottles, infusion jars, chromatography bottles, milk test jars, cylindrical bottles, reagent joints, ball and socket or standard taper bottles, weighing manometers bulbs, absorption percolators bulbs, leveling pycnometers bulbs, sampling stopcocks burets tubes, centrifuge condensers tubes, chromatography crystallizing dishes tubes, color comparison (turbidity) culture dishes tubes, combustion (ignition) custom apparatus tubes, connecting and adapter cylinders, graduated tubes, digestion and plain tubes, drying desiccators tubes, fermentation extraction tubes tubes, thistle (spray traps) flasks vapor traps fritted ware viscometers funnels watch glasses generators, Kipp grinder, tissue 1.3 This specification recognizes that photoelastic measurements are proportional to the difference of the principal stresses. The limit imposed represents a safety factor to cover a situation in which one of the principal stresses may be larger than the apparent stress. 1.4 This specification applies only to annealed glassware that is intended for sale as such. It excludes glassware that has been thermally tempered, ion-exchanged, or laminated with glass layers of differing expansion. The intent of this specification is to limit the residual stresses for safe consumer use in annealed glass, as it leaves the manufacturer. 1.5 Stresses introduced by thermal expansion differences within the glassware are covered by this specification. Graded and glass-to-metal seals are excluded.
