What is BS EN ISO 31820:2012


BS EN ISO 31820:2012 is a professional technical standard that relates to the application of structural fire protection to steel structures. This standard provides guidelines and requirements for designing, installing, and maintaining fire protection systems in order to protect steel structures from the damaging effects of fire. It sets out the criteria for selecting suitable materials and the methods for applying them to the surfaces of structures. In this article, we will explore the key aspects of BS EN ISO 31820:2012 and its significance in ensuring the safety of steel structures in fire incidents.

Key Requirements

One of the primary objectives of BS EN ISO 31820:2012 is to ensure that the fire protection measures applied to steel structures are effective and can withstand the effects of fire for a specified period of time. The standard encompasses a range of criteria and guidelines for assessing the performance of these protective systems. This includes the determination of fire resistance ratings based on factors such as the duration of fire exposure, the load-bearing capacity of the structure, and the type of fire scenario being considered. Additionally, the standard provides guidance on the inspection, testing, and maintenance of fire protection systems to ensure their ongoing effectiveness.

Material Selection and Application

BS EN ISO 31820:2012 outlines the requirements for selecting and using appropriate materials for the fire protection of steel structures. This includes evaluating the thermal properties, durability, and compatibility of the materials with the underlying steel substrate. Different types of fire protection materials, such as intumescent coatings, cementitious sprays, and board systems, are discussed in the standard, along with their specific application methods and limitations. Ensuring proper surface preparation and application techniques are followed is crucial to achieving the desired fire resistance performance.

Importance of BS EN ISO 31820:2012

The implementation of BS EN ISO 31820:2012 is of paramount importance in safeguarding steel structures against fire hazards. By adhering to the guidelines set out in this standard, designers, engineers, and construction professionals can ensure that appropriate fire protection measures are incorporated into their projects. This helps to minimize the risk of structural failure during a fire event and provides valuable time for safe evacuation and firefighting operations. Furthermore, compliance with BS EN ISO 31820:2012 demonstrates a commitment to safety and regulatory compliance, enhancing confidence among stakeholders and regulators.
