What is BS EN 1947 - Firefighting hoses about?
A firefighting hose is a high-pressure firefighting hose attached to a fire engine or fire hydrant and used by firefighters to carry water or firefighting foam to extinguish a fire. BS EN 1947 discusses standards for semirigid delivery hoses and hose assemblies for pumps and vehicles.
BS EN 1947 specifies the requirements and test methods for semi-rigid hoses for use on firefighting vehicles and trailer pumps. The hoses are intended for use at a maximum working pressure of 1,5 MPa for normal pressure hoses (category I) and 4,0 MPa for high-pressure hoses (category II). The hoses are further subdivided into types and classes.
BS EN 1947 applies to hoses for fire-fighting purposes intended for use at ambient conditions within the temperature range −20 °C to +60 °C. Hoses conforming to BS EN 1947 are intended for use with fire hose couplings conforming to the relevant national standards for couplings. BS EN 1947 also provides requirements for hose assemblies where these are fitted by the hose manufacturer.
Who is BS EN 1947 - Firefighting hoses for?
BS EN 1947 on fire-fighting hoses is useful for:
- Manufacturers and suppliers of fire-fighting hoses
- Firefighting team
- Fire protection service providers
- Entities involved in fire safety engineering
- Design engineers
- Regulatory authorities
- Quality control personnel
- Inspection bodies
Why should you use BS EN 1947 - Firefighting hoses?
Semi-rigid delivery hoses are used by the fire service and incorporates those hoses used manually to control and extinguish fires. The hose requires to be fitted with couplings to form a hose assembly which is fitted onto reels on fire fighting vehicles.
BS EN 1947 describes the classification of hoses including classification by types, classification by class, and classification by category which ensure that all types and classes of the hoses are so flexible. BS EN 1947 provides you with dimensions, tolerances and maximum mass for the semi-rigid hoses used for fire-fighting purposes. Following specifications in BS EN 1947, help you to assess the performance of finished hoses.
BS EN 1947 also provides you with a test method for testing the security of the hose assembly. EN 1947 guidelines help you to ensure the quality and functionality of fire-fighting hoses. These hoses will be able to respond safely at short notice to hazardous situations when firefighting.
