Deflection Testing

Deflection testing is performed using an odd-legged mandrel pulled through the pipe without mechanical assistance. The mandrel size shall be the actual inside diameter of the subject minus 5% of that diameter. The mandrel shall have no less than nine legs. Any pipe failing any deflection test shall be removed and replaced.
