BS 5041-1 discusses components for fire hydrant systems. The aim of the BS 5041 series is to provide best industry requirements for the safe and reliable use of fire hydrant systems, such that they play a positive role during a fire emergency.
BS 5041-1 is the first part of the BS 5041 series that specifies requirements for copper alloy globe valves generally complying with BS 5154 and diaphragm valves generally complying with BS 5156, both suitable for installation as landing valves on wet risers. The valves have screwed or flanged inlets and also delivery hose connections complying with BS 336.
This standard covers valves of nominal pressure (PN) designations 15 bar and 20 bar and nominal inlet sizes DN 40 to DN 65 for flanged ends and 1½ and 2½ for screwed ends.
BS 5041-1 on landing valves for wet risers is useful for:
Fire hydrants are the most commonly used water-based suppression systems for general fire fighting requirements. A fire hydrant, also called a fireplug, fire pump, johnny pump, or simply pump, is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. To prevent hazardous situations, it is necessary that fire hydrant systems and their accessories are designed and built as per best industry performance requirements.
BS 5041-1 provides you with requirements and test methods that can be followed while manufacturing landing valves for wet risers. This can ensure that landing valves for wet risers supply the necessary water pressure that are necessary for buildings (and structures) that are too high for brigade pumps.
BS 5041-1 helps in the evaluation of conformity of product that verifies if the performance declarations represent the true behavior of the product.
If you are a manufacturer, BS 5041-1 can ensure that your landing valves for wet risers contribute to the operational efficiency of the gas extinguishing system and contribute to a successful fire response.
