TS CR 10260

TS CR 10260 addresses the additional symbols used in the short designation system for steels, as a complementary document to EN 10027-1 and EN 10027-2. Taken with the title and scope together, it is clear that this standard focuses on the extra marks that support steel designation, rather than on the basic classification framework itself.

The role of additional symbols in steel designation

In general technical terms, a short designation system for steels is meant to express key information about a steel grade in a compact and structured code. Additional symbols are the elements that refine that code and help distinguish one grade or product condition from another within the same basic family. In common industry use, such symbols may help indicate matters such as processing condition, special treatment, or other distinguishing features. This standard is concerned with how those additional symbols are appended within the EN 10027-1 and EN 10027-2 framework; it does not re-establish the primary designation rules themselves.

Position of the document and its practical context

This is a supplementary document, not the main standard that independently defines the steel designation system. In practice, it helps keep designation practice consistent and supports harmonised interpretation of symbols across related standards. Read together with the referenced EN 10020, EN 10027-1, EN 10027-2 and EN 10079 documents, it contributes to a shared technical language for steel classification, designation and terminology. The document was later withdrawn, but it remains relevant as a historical complement within the development of the steel designation system.
