Mechanical Requirements of EN10255

For welded tubes the tolerance on wall thickness is: ± 10 % .
for M and H series and Type L: – 8 % with the plus tolerance limited by the mass tolerance, for Types L1 and L2.
The mass tolerance on welded tubes is:
 ± 7,5 % on bundles of 10 tons or more, for M and H series and Type L ;
 +10% -8% on individual tubes for Types L1 and L2.
For seamless tubes the tolerance on wall thickness is ± 12,5 %.
The maximum tolerance does not apply if the actual weight of a bundle does not exceed the theoretical weight, calculated from the nominal mass per unit length (see Tables 2, B1, B2, or B3, as appropriate), by more than + 7,5 %.
