Delivery requirements for surface condition of hot rolled steel plates, wide flats and sections; part 1: general requirements

This document establishes the fundamental delivery requirements concerning the surface condition of hot-rolled steel products. It serves as a primary reference for ensuring that the visual and physical characteristics of the steel surface meet agreed-upon standards between manufacturers and suppliers. The text outlines general principles applicable to the assessment of surface quality, covering aspects such as imperfections, finishes, and cleaning procedures. It provides a framework for defining what constitutes acceptable surface conditions for various types of hot-rolled steel, facilitating uniformity in trade and technical specifications across different regions. The content details the classification of surface defects and the methods for their identification and acceptance criteria. By setting these baseline rules, it helps in maintaining consistency in the quality of materials supplied for industrial applications. The guidelines address the necessary checks and balances required during the delivery process to ensure that the steel meets the specified condition standards without requiring excessive rework or rejection due to minor surface variations. This specification is widely referenced in the procurement of steel for manufacturing sectors.
