What is BS EN ISO 9239-2:2014?

Introduction

BS EN ISO 9239-2:2014 is a professional technical standard that specifies a laboratory test method for measuring the flame spread properties of floor coverings exposed to a small igniting flame. This standard was developed by the European Committee for Standardization (CEN) in collaboration with the International Organization for Standardization (ISO). It provides valuable information on the fire performance of different types of flooring materials and helps ensure the safety of buildings and their occupants.

Scope and Objectives

The main purpose of BS EN ISO 9239-2:2014 is to determine the critical radiant flux of a horizontal floor covering system. This value indicates the heat exposure necessary for a fire to spread across the surface of the floor covering. By conducting this laboratory test, manufacturers and regulatory bodies can assess the fire resistance of various flooring materials and make informed decisions regarding their use in different building applications. The standard covers a wide range of flooring products, including carpets, resilient flooring, laminates, and wood flooring.

Testing Procedure

The testing procedure outlined in BS EN ISO 9239-2:2014 involves exposing a horizontally mounted floor covering specimen to a defined radiant heat source. The specimen is subjected to continuous radiation until it either self-extinguishes or reaches a specified burn length. During the test, various data points such as heat release rate, smoke production, and flaming droplets are measured. These measurements provide insights into the fire behavior and performance characteristics of the tested flooring material. The test should be conducted in a controlled laboratory environment following strict safety protocols.

Importance and Benefits

BS EN ISO 9239-2:2014 is an essential standard for manufacturers, architects, regulatory bodies, and other stakeholders involved in the construction industry. It sets clear criteria for evaluating the fire performance of floor coverings, enabling informed decision-making regarding their suitability for different building applications. Compliance with this standard helps ensure the safety of occupants, as it assists in preventing the rapid spread of fires through flooring systems. By testing and classifying flooring materials according to their fire resistance, this standard contributes to creating safer built environments.
