QC4: Check for damaged fibers
Inspect the WLS fibers from the point where they exit
the profile to the point where they enter the aspirin tube. Look for any
of the following problems:
Broken fibers.
Stress crazing of the cladding.
Knick or scratches in the cladding.
Fibers with sharp bends (radii less than 50 mm).
Fibers in direct contact with the weld bars or corners
of the girder.
Repair or replace fibers with any of these problems.
Sign and date the check
sheet.
Report any serious or recurrent problems.
