What is BS EN 45551-3:2017 ?

Title: What is BS EN 45551-3:2017 and BSEN 4555-12:2017?

Civil engineering structures are built to withstand various external factors such as fire, explosions, and projectiles. To ensure the safety and integrity of these structures, protective systems are installed in the construction industry. Two such standards are BS EN 45551-3:2017 and BSEN 4555-12:201In this article, we will discuss the purpose and key components of these standards.

BSEN 45551-3:2017: The Purpose of BSEN 45551-3:2017

BSEN 45551-3:2017 is a technical standard developed by the European Committee for Standardization (CEN) and applies to the selection and use of materials for protective systems in civil engineering structures. This standard focuses on the performance requirements for protective systems for civil engineering structures, ensuring the safety and integrity of the structures.

BSEN 45551-3:2017 sets minimum requirements for various attributes such as mechanical properties, flame resistance, and chemical protection. Compliance with this standard indicates that the material has undergone rigorous testing and meets recognized safety standards.

BSEN 4555-12:2017: The Purpose of BSEN 4555-12:2017

BSEN 4555-12:2017 is a technical standard developed by the International Organization for Standardization (ISO) that provides guidance on the evaluation of the performance of protective clothing. This standard is applicable to clothing designed to be worn in high-risk environments or for protection against specific hazards.

BSEN 4555-12:2017 sets minimum requirements for various attributes such as mechanical properties, flame resistance, and chemical protection. Compliance with this standard indicates that the clothing has undergone rigorous testing and meets recognized safety standards.

Key Elements of BSEN 45551-3:2017 and BSEN 4555-12:2017

2.1 What is mechanical properties?

Mechanical properties are the properties of materials that describe their ability to resist external forces, such as stress, strain, and deformation. Mechanical properties are essential for the selection of materials for protective systems, as they determine their resistance to various hazards.

2.2 What is flame resistance?

Flame resistance is a material's ability to withstand the heat and light of a fire without igniting or catching fire. In high-risk environments, such as construction sites, protective clothing is crucial to prevent fire or ignition of flammable materials.

2.3 What is chemical protection?

Chemical protection refers to the ability of materials to resist chemical hazards, such as acid, alkali, or chemical agents. In certain applications, such as chemical plants or industrial facilities, chemical protection is essential to prevent damage or injury to the structure.

Conclusion:

BSEN 45551-3:2017 and BSEN 4555-12:2017 are essential technical standards for the selection and use of materials in the construction industry. They provide guidelines for protective systems, focusing on the performance requirements for civil engineering structures. By adhering to these standards, professionals can make informed decisions regarding material selection, installation methods, and performance criteria, enhancing the overall durability and resilience of civil engineering structures.
