This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 135.

This draft amendment A1, if approved, will modify the European Standard EN 1090-2:2018. If this draft becomes an amendment,
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of
this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

8 Modification to 6.4.4
Add at the end of 6.4.4:
For all steel categories listed in 3.16 Table HSS, it will be checked with the steel manufacturer whether
preheating of the material is necessary for thermal cutting. As an alternative, the cut edges may be
machined to remove the hardened layer and thus ensure the parent metal properties.

1 paragraph, replace:
"Steel may be bent, pressed or forged to the required shape by either a hot or cold forming process,
provided the properties are not reduced below those specified."
