The primary goal of ASME B106.1M is to prevent failure in rotating shafts. In any mechanical system, shafts are the "backbone" that transmits torque and power. Because they are often subjected to a combination of bending moments, torsional loads, and axial forces, a simple calculation is rarely sufficient.
ASME B106.1M is a standard published by the American Society of Mechanical Engineers (ASME) that provides guidelines for the design, materials, fabrication, testing, and inspection of pipeline transportation systems. Asme B106.1m Pdf
