Applies to cold reduced mild unalloyed steel flat products (sheet and strip), without coating in thicknesses up to and including 3 mm as specified in Table 1. These steels have been rendered suitable for vitreous enamelling as a result of special processing. Subject to agreement, this standard may also be applied to cold reduced flat products made of these steels in thicknesses over 3 mm up to approximately 4 mm.
