 Subclauses 5.7 and 6.2.6: Requirements to stress corrosion cracking resistance are included (from
former Annex A in Part 2)
 Subclause 6.1.1: For samples for chemical analysis reference is made to EN 14361
 Subclause 6.1.3.3: For shapes and dimensions of test pieces reference is made to EN 10002-1 (and
former Annex A is deleted)
 Clause 7: For inspection documents, reference is made to EN 10204
 Annex B: Annex B Resistance to stress corrosion cracking – Electrical conductivity is added (taken from
former Part 2)
