The inherent out-of-round condition of the pipe willcause the thread dimensions to conform to the irregularities ofthe pipe. Measurements must be taken at many points andaveraged. Alternatively gages of metal or other rigid materialmay be used when gage dimensions or methods are available.6.7.3 Thread Out-of-Ro
