What is BS EN ISO 5996:2010?

BS EN ISO 5996:2010, also known as BS EN ISO 5996:2010, is a professional technical standard that provides specifications for steel sheet and strip intended for applications requiring corrosion resistance, formability, and high strength. This standard was published by the British Standards Institution (BSI) and is widely recognized in the industry.

Scope and Application

This standard covers hot-rolled steel sheet and strip of structural quality with improved atmospheric corrosion resistance, commonly referred to as weathering steel. It applies to steel products that are manufactured in thicknesses of up to 12.5mm and widths up to 2,000mm. The standard provides guidelines relating to chemical composition, mechanical properties, and tolerances for dimensions and shape.

Chemical Composition and Mechanical Properties

According to BS EN ISO 5996:2010, the steel must meet specific requirements for chemical composition, including elements such as carbon, manganese, phosphorus, sulfur, silicon, copper, chromium, nickel, and others. These elements contribute to the material's corrosion resistance, formability, and strength properties.

In terms of mechanical properties, the standard outlines requirements for tensile strength, yield strength, elongation after fracture, and impact strength. These properties ensure that the steel sheet and strip can withstand various types of loads and environmental conditions.

Product Marking and Certification

The standard specifies the methods for product marking, including labels or information tags, to indicate compliance with BS EN ISO 5996:2010. Additionally, it provides guidelines for the certification process to ensure that the steel manufacturers adhere to the specified requirements before placing their products on the market.

Compliance with this standard enables customers and end-users to have confidence in the quality and performance of the steel sheet and strip, as it indicates that the material has been tested and approved against recognized industry standards.

In conclusion, BS EN ISO 5996:2010 is an important technical standard for steel sheet and strip, providing specifications for corrosion resistance, formability, and high strength. Its scope covers hot-rolled steel products with improved atmospheric corrosion resistance, while its requirements for chemical composition and mechanical properties ensure reliable performance. Compliance with this standard supports the credibility and reliability of steel manufacturers in meeting customer expectations.
