The Thai Industrial Standards Institute (TISI) has proposed to revise the draft Thai Industrial Standard for Hot-Rolled Flat Steel of Commercial and Drawing Qualities (TIS 528-25XX(20XX)). This revision replaces the draft standard previously notified to WTO/TBT under G/TBT/N/THA/149/Rev.1.
The major revisions include amending the definition and adding more grade for hot-rolled flat steel: HR5.
