What is BS EN 1794-3 - Burning behaviour of noise reducing devices and classification about?
BS EN 1794-3 is a European Standard that discusses road equipment.
BS EN 1794-3 is to give authorities, designers, and specifiers information with respect to reaction to fire, smoke density, and toxic fumes of materials used in noise-reducing devices.
The combination of brushwood fire test, smoke density test and test for toxic fumes give in general enough safety information. BS EN 1794-3 also gives information if more stringent requirements are requested for situations with a higher level of safety.
For noise reducing devices, this European Standard gives a method how to handle substantial components of non-homogeneous products (as defined in EN 13501-1 and ISO/DIS 5659-2:2016) and how to handle non-homogeneous products and in which cases the influence of non-substantial components on the total result of the classification may be neglected.
Who is BS EN 1794-3 - Burning behaviour of noise reducing devices and classification for?
- BS EN 1794-3 on burning behaviour of noise-reducing devices and classification is useful for:
- Road management authorities
- Manufacturers of noise-reduction devices
- Acoustic engineers and
- Product designers
Why should you use BS EN 1794-3 - Burning behaviour of noise reducing devices and classification?
While performing their primary function, road traffic noise reducing devices should not pose hazards to road users or other people in the vicinity or to the environment at large. Noise-reducing devices should not reflect light in such a way as to prejudice road safety.
BS EN 1794-3 contains indications for smoke hazard; density and toxic fumes, because this could create dangerous situations for the traffic and nearby living people. Test for smoke density and toxic fumes are necessary in all cases.
In this regard, BS EN 1794-3 defines the burning behaviour of noise reducing devices and classification to assess the performance of road traffic noise reducing devices under typical roadside conditions.
Noise-reducing devices that comply with BS EN 1794-3 give information if more stringent requirements are requested for situations with a higher level of safety as well as access for employees in the event of an emergency or for maintenance. BS EN 1794-3 also ensures product failure from collapse/detachment is prevented with fastening requirements, thus minimizing the risk of injury for road-users.
