What is BS EN 1279 2 ?

Title: What is BS EN 1279 2? A Technical Article by British Standards Institution (BSI)

The construction industry places a great emphasis on safety and quality. As new materials and technologies are introduced, it is essential to have standardized testing methods to evaluate their fire performance. This is where BS EN 1279 2 comes in. BS EN 1279 2 is a technical standard that defines the test method for asphalt mixtures, providing guidelines and procedures for determining various properties and performance characteristics of asphalt mixes. In this article, we will explore the significance of BS EN 1279 2 and how it plays a vital role in ensuring the safety of buildings.

Purpose of BS EN 1279 2:

BS EN 1279 2 is a technical standard that provides a framework for assessing the fire performance of construction products and elements used in building envelopes. It classifies materials based on their reaction to fire and establishes criteria for measuring their ability to resist flames, heat, and smoke development during a fire. By providing a standardized system for evaluating the fire performance of materials, BS EN 1279 2 aims to provide builders, regulators, and consumers with a reliable system for understanding the fire hazards associated with specific materials and making informed decisions about their use.

Key Components of BS EN 1279 2:

BS EN 1279 2 has several key components that are essential for evaluating the fire performance of materials. These include:

Fire Tests: BS EN 1279 2 outlines the fire tests that materials must undergo to ensure they are suitable for use in building envelopes. These tests include slow-burning tests, thermal decomposition tests, and fire-extinguishing tests.

Fire-Resistance Groups (FRGs): BS EN 1279 2 defines FRGs, which are groups of materials that are expected to resist fire for a specific period of time. These groups are based on the fire-resistance time (FRT) class, which is the amount of time a fire can be sustained.

Surface Burning Characteristics: BS EN 1279 2 specifies the surface burning characteristics of materials, which are critical in determining how hot a fire will develop and how long it will be able to persist. These characteristics include the flaming distance, which is the distance from the surface of the material to the point of ignition, and the self-extinguishing time, which is the time it takes for a fire to be fully extinguished when it is not treated.

Significance of BS EN 1279 2:

BS EN 1279 2 plays a vital role in ensuring the safety of buildings by providing a standardized system for evaluating the fire performance of materials. By establishing criteria for measuring the fire performance of materials, BS EN 1279 2 provides builders, regulators, and consumers with a reliable system for understanding the fire hazards associated with specific materials and making informed decisions about their use.

Conclusion:

BS EN 1279 2 is a technical standard that defines the test method for asphalt mixtures, providing guidelines and procedures for determining various properties and performance characteristics of asphalt mixes. It is essential for evaluating the fire performance of construction products and elements used in building envelopes. By providing a standardized system for evaluating the fire performance of materials, BS EN 1279 2 plays a vital role in ensuring the safety of buildings and contributes to the development of durable and sustainable roads.
