— introduction of normative references EN 515 (as mentioned in Clause 4) and NF A 50-800-2 and NF A 50-
800-3 (as mentioned in Subclause 10.4) as applying to ballistic testing and requirements, in Clause 2;
— introduction of Clause 3 as required by the latest edition of CEN template;
— simplification of Table 1 in Clause 4;
— merging former Subclauses 4.1 and 4.2 in single Clause 5;
— additional information included in Subclause 6.1;
— rewording of Subclause 6.2;
— change in stress corrosion testing conditions and acceptance criteria for ARAL1 material (Subclause 6.3
and Annex A);
— rewording of title and text of Subclause 6.4;
— rewording in Subclause 6.6;
— simplification of Subclauses sequence in Clause 7;
— rewording of Subclauses 8.2 to 8.8;
