This European Standard specifies the requirements and test methods for non-percolating layflat hoses for fixed systems. The hoses are intended for use at a maximum working pressure of 1,5 MPa over a range of inside diameters from 25 mm to 52 mm. The standard applies exclusively to hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 °C in normal conditions, and a minimum temperature of -30 °C in colder climatic conditions.
