Bright Bar Dimensional Tolerances B.S.970 Part 3 1991

Notes:
1. Thickness shall be measured within 12mm of the edge for flats.

2. The diameter of round bars in the as drawn length shall be measured at a distance of at least 150mm from the end of the bar. Where round bars have been re-cut to a exact length the diameter shall be measured at least 10mm from the end of the bar.

3. The cross-sectional measurement of hexagons, squares and flat bars shall be measured at least 25mm from the end of the bar.

Note: The very ends of such bars might not necessarily meet the requirements of table 1 but these should not be regarded as defective if the remainder is in accordance with the above table.

EN10278 - 1999

Out of section          
 Maximum deviation from "out of round" or "difference between opposing faces" for squares or hexagons shall neither be greater than half the specified tolerance nor above the upper limit of the tolerance.          
           
Edges of non-round bars (flats, squares, hexagons)          
           
Dimension ≤ 150mm - bars may have an undefined profile within 0.2mm of the hypothetical corner.          
           
Dimension > 150mm - bars may have an undefined profile within 0.5mm of the hypothetical corner unless sharp corners specifically agreed.          
           
In the case of flat products the width is the controlling dimension.          
         

Dimensional Inspection              
Round bars  - not less than 150mm from end of bar.        
Round bars - cut to length - not less than 10mm from end of bar.        
Non-round bars  - not less than 25mm from end of bar.        

These tables have been prepared for guidance purposes only and reference should be made.
