Angular displacement shall be measured in degrees with a tolerance of 3 for lengths up to 2 feet (61 cm) and 5 for all lengths over 2 feet (61 cm). 4. The angular displacement shall be expressed in two digits
11、 number of degrees divided. 5. Making the angular determination in the wrong direction will result in an unacceptable part. FIGURE 3. Elbow fitting drop height and angular alignment.
