Fire-fighting hoses - Non-percolating layflat hoses for fixed systems in marine applications cen:proj:64903

Scope

This European Standard specifies the requirements and test methods for non-percolating layflat hoses for fixed systems in marine applications. 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 75 mm.
This European 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 and a maximum ambient temperature of +60 °C.
NOTE 1 Hoses for use at ambient temperatures below −20 °C can be supplied if they have been tested at the specified lower temperature in accordance with 6.4 and identified by their marking in Clause 8 f).
NOTE 2 All pressures are gauge pressures and are expressed in megapascals
