A list of modifications with the explanations is given in annex 1 informative. The most recent editions of the standards including the amendments shall be applied. The process DA means a process wherein wire rods having been cold worked are annealed and further finished by cold working or a process wherein wire rods are finished by cold working after annealing.

However, manufacturing processes other than given above may be selected by agreement between the purchaser and the supplier. However, in the case by processes other than process D and process DA, they shall be subjected to the agreement between the purchaser and the supplier. Over 3 to and incl. Over 4 to and incl.
