Should there be a distraction from the view beyond by something like a scratch in the surface or a bubble in the body of the glass this can be inspected to determine whether it can be classified as a defect under the referenced standards and specification. The glass material will either be crystal or standard glass. Deformation associated with listric (downward flattening) normal faults produces very interesting patterns. For glass containers the critical faults are broken, cracked, or chipped glass, strands of glass stretched across the inside of new packs, or bubbles in the glass that make it very thin in places. The specifier should not specify viewing criteria or distances more stringent than those in the BS EN Standards for the glass in question as the glass supplier will be unable to impose tighter standards except possibly with regard to overall bow, local bow and rollerwave in heat strengthened or toughened glass.
