GeneralThe standard DIN 11850 has been withdrawn 2013 and replaced by EN 10357.
In the EN 10357:2022 version, the section on ‘Manufacturing processes’ has been updated. For example, the old term ‘BD’ has been replaced by ‘CL1 BD,’ and an additional option ‘CL2 BD’ has been introduced that specify Ra<0.8μm on the inside weld.
This is done on all options, (CC, CD, BC & BD).
