What is BS EN 16497-1 - Non-balanced flue applications of concrete system chimneys about?
BS EN 16497-1 is the first part of the multiple series that specifies the materials and the dimensional and performance requirements for straight concrete system chimneys for non-balanced flue applications comprising a concrete flue liner and a combination of compatible chimney components, which may be concrete flue blocks (see Clause 4), obtained or specified from one manufacturing source with product responsibility for the whole chimney.
BS EN 16497-1 also applies to concrete system chimneys constructed from storey-height elements and flue blocks reinforced for handling.
Note 1: BS EN 16497-1 does not apply to concrete system chimneys with back ventilation.
Note 2: BS EN 16497-1 does not cover products designated wet (W) in conjunction with corrosion class 3.
Who is BS EN 16497-1 - Non-balanced flue applications of concrete system chimneys for?
BS EN 16497-1 on concrete system chimneys is useful for:
- Contractors and architects
- Environmental auditors
- Chimney manufacturers and suppliers
- Regulatory authorities
- Testers of chimney
- Installers of chimney
Why should you use BS EN 16497-1 - Non-balanced flue applications of concrete system chimneys?
Concrete material is formed by mixing cement, coarse and fine aggregate and water with or without the incorporation of admixtures or additions, which develops its properties by hydration of the cement.
BS EN 16497-1 covers concrete system chimney to comprise of flue blocks, which is of a single wall or multi-wall construction. It specifies materials for insulation forms part of a system chimney.BS EN 16497-1 also includes a factory production control system to ensure that the products placed on the market comply with the declared performance of the essential characteristics.
Overall, BS EN 16497-1 specifies non-balanced flue applications, which help you for testing flow resistance and wind velocity pressure at least.
