What is BS EN 2825 - Smoke density from burning of non metals in aerospace about?
Product and component quality is paramount for aerospace vessels. The delivery of high-quality components contributes to the safety of those on board.
BS EN 2825 defines a test method for the determination of the smoke density due to pyrolytic decomposition of solid materials and composite materials of up to 25 mm in thickness under the influence of radiant heat only or with the simultaneous flame application.
The test results enable a comparison of the smoke production of different materials or material configurations under the conditions specified in BS EN 2825.
Note 1: The smoke gas density is determined according to the specific environmental and test conditions defined in EN 2824 and BS EN 2825. No studies have been made up to now to determine whether the results can be transferred to differing conditions, particularly to actual fire conditions.
Note 2: The burning behaviour - and consequently the smoke density - of aerospace materials is not only influenced by the type of material but also to a large extent by the configuration, the specific surface, and mass, the combination with other materials, the means of joining as well as the processing technique.
Who is BS EN 2825 - Smoke density from burning of non metals in aerospace for?
BS EN 2825 on smoke density from burning of nonmetals in aerospace is useful for:
- The aerospace and defence industry
- Manufacturers of aerospace equipment and components
- Vendors / Manufacturers and suppliers of non-metallic materials for aerospace
- Purchase divisions/component sourcing personnel
- Product design engineers
- Aeronautical engineers
Why should you use BS EN 2825 - Smoke density from burning of non metals in aerospace?
Smoke density test measures the amount of smoke given off by a material that is burning or smoldering. The material is tested when it begins to smolder and again when a flame source is added. The smoke density is between 0 (no smoke generated) and 800. Most finishes and materials require a rating of 450 or less.
BS EN 2825 provides you with the requirements for the determination of the smoke density due to pyrolytic decomposition of solid materials and composite materials of up to 25 mm in thickness under the influence of radiant heat only or with a simultaneous flame application for aerospace so that the products are suitable for the required purpose.
The guidelines in BS EN 2825 contribute towards including high-quality components for aerospace that are responsible for the smooth and safe functioning of vessels.
