    Abstract

    This specification covers a limit for thermal residual stress in reusable annealed glass laboratory apparatus as determined by prescribed photoelastic measurement procedures. This specification recognizes that photoelastic measurements are proportional to the difference of the principal stresses. The stress limit shall be measured and calculated to meet the specified requirements.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    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.
