What is the difference between bs7176 and bs5852?
BS 7176 and BS 5852 are two British Standards that pertain to different aspects of fire safety in the furniture and textile industries. Here's a breakdown of each standard and the main differences between them:
1. BS 7176:
BS 7176 is a British Standard that specifies the requirements for resistance to ignition of upholstered furniture for non-domestic seating. It is primarily used to assess the fire safety performance of upholstered seating in public spaces, such as offices, hotels, hospitals, and schools.
This standard outlines the test methods and performance criteria for assessing the resistance of upholstered furniture to ignition by smoldering cigarettes and flaming sources. It includes tests for the cover fabric, foam filling, and composite assemblies to evaluate factors such as ignition resistance, heat release rate, and smoke production.
BS 7176 categorizes furniture into different hazard levels based on the environment in which it will be used. There are three hazard levels: low hazard (general use), medium hazard (e.g., hotels and offices), and high hazard (e.g., hospitals and nursing homes). The standard specifies the testing requirements for each level, with higher hazard levels requiring more stringent fire safety performance.
2. BS 5852:
BS 5852 is a British Standard that provides test methods and requirements for the resistance to ignition of materials used in upholstered furniture, such as fabrics, foams, and fillings. This standard applies to both domestic and non-domestic upholstered furniture and evaluates their fire safety performance.
BS 5852 specifies several test methods, including the cigarette resistance test, match flame resistance test, and the composite foam block test. These tests assess the ignition resistance and behavior of upholstered furniture under specific ignition sources and evaluate factors such as ignition time, flame spread, and heat release.
The purpose of BS 5852 is to ensure that the materials used in upholstered furniture meet specific fire safety standards and do not contribute significantly to the spread or intensity of a fire.
Key differences:
The main difference between BS 7176 and BS 5852 lies in their scope and application:
- BS 7176 focuses specifically on upholstered furniture for non-domestic seating in public spaces, addressing fire safety concerns specific to these environments.
- BS 5852, on the other hand, applies to a broader range of materials used in upholstered furniture for both domestic and non-domestic settings. It encompasses materials like fabrics, foams, and fillings and covers a wider range of ignition sources and test methods.
It's important for manufacturers and suppliers in the furniture and textile industries to comply with the relevant fire safety standards applicable to their intended markets to ensure product safety and regulatory compliance. Both standards play a crucial role in assessing the fire performance of upholstered furniture, with BS 7176 focusing on non-domestic seating and BS 5852 covering various materials used in upholstered furniture.
