scope:

This International Standard specifies the requirements for four types of textile-reinforced thermoplastics collapsible water hoses for general applications for use in the temperature range of -10ºC to 55ºC. Such hoses are classified into four types, as follows: . low pressure, designed for a maximum working pressure of up to 0,4 MPa (4,0 bar) at 23ºC and up to 0,2 MPa (2,0 bar) at 55ºC; . medium pressure, for a maximum working pressure of up to 0,7 MPa (7,0 bar) at 23ºC and up to 0,36 MPa (3,6 bar) at 55ºC; . high pressure, for a maximum working pressure of up to 1,0 MPa (10,0 bar) at 23ºC and up to 0,51 MPa (5,1 bar) at 55ºC; . extra-high pressure, for a maximum working pressure of up to 1,55 MPa (15,5 bar) at 23ºC and up to 0,79 MPa (7,9 bar) at 55ºC. This standard does not apply to products used for fire-fighting or the conveyance of drinking water.
