3.5
visual faults
faults, that alter the visual quality of the glass. These are spot faults and linear/extend faults with patterned faults
and/or wire faults depending on type of product

3.7
concentration, c
sum of the lengths of gaseous inclusions > 1,0 mm in any circle of 400 mm diameter
[Drawn sheet glass EN 572-4]
3.8
linear / extended faults
faults, which can be on or in the glass, in the form of deposits, marks or scratches that occupy an extended length
or area
3.9
pattern faults
deviations of the pattern relative to a reference, e.g. line or straight edge
[Patterned and patterned wired glass EN 572-5, EN 572-6]
3.10
deviation of the pattern
deviation, x, of the pattern.
3.11
wire faults
deviations of the wire, penetration of the glass surface by the wire or break in the wire in the body of the glass
[Polished wired and patterned wired glass EN 572-3, EN 572-6]
3.12
deviation of the wire
deviation, y, of the wire relative to a reference, e.g. line or straight edge
3.13
edge defects
defects, which can occur on the edge of a cut size piece in the form of entrant and emergent faults and / or bevels
