Title: What is BS EN 45505-3: 2017 and BS EN 4555-12: 2017?

Civil engineering structures are built to withstand various external factors such as fire, explosions, and projectiles. The safety and integrity of these structures are crucial, and the materials used in their construction must meet certain performance requirements. Two such technical standards are BS EN 45505-3: 2017 and BS EN 4555-12: 201In this article, we will discuss the purpose and key components of these standards.

BS EN 45505-3: 2017: The Purpose of BS EN 45505-3: 2017

BS EN 45505-3: 2017 is a technical standard developed by the European Committee for Standardization (CEN) and applies to the selection and use of materials in the construction industry. It focuses specifically on the performance requirements for protective systems for civil engineering structures.

The primary objective of BS EN 45505-3: 2017 is to ensure the safety and integrity of civil engineering structures by specifying the minimum requirements for protective systems. These protective systems are designed to mitigate the impact of external factors such as fire, explosions, and projectiles.

BS EN 4555-12: 2017: The Purpose of BS EN 4555-12: 2017

BS EN 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.

The purpose of BS EN 4555-12: 2017 is to provide manufacturers, regulators, and users with a tool to assess the overall effectiveness of protective clothing. It sets minimum requirements for various attributes such as mechanical properties, flame resistance, and chemical protection.
