Quality:
Lengths of finished tubing is reasonably straight and have smooth ends free from burrs.
Tubing is free from scale and injurious defects and have a workmanlike finish.
Surface imperfections such as handling marks, die marks, or shallow pits shall not be considered injurious
defects provided the imperfections are within the tolerance specified for diameter and wall thickness.
The removal of such surface imperfections is not required.
PERFORMANCE REQUIREMENTS:
The finished tubing satisfactorily meet the following performance tests in SAE J1677
