23、ot exceed the maximum given in Table 1. 4.6 web off centre (e) The mid-thickness of the web shall not deviate from the mid-width position on the flange by more than the distance (e) given in Table 1. 4.7 straightness (qxx or qyy) The straightness shall comply with the requirements given in Table 1.

24、5 tolerance on mass The mass of a batch or piece shall be within 4.0% of the calculated mass (seeTable 1). The mass deviation is the difference between the actual mass of the batch or piece and the calculated (theoretical) mass. The calculated mass shall be determined using a density of7.85kg/dm 3 .
