NOTE 2 Due to pressurization during test and operations the temperature of the fluid could increase. The
indicated temperatures are measured at atmospheric pressure;
a
Class A is for use onshore.
b
Class B is for use offshore.
Upon agreement with the manufacturer, lower min and/or higher max temperature are allowed depending
on the materials used and the compatibility at those temperatures with the fluid conveyed. Other properties
and requirements mentioned in the standard still shall be met.
5 Materials and construction
Hoses shall be constructed as shown in Figure 1 and shall consist of the following:
a) Class A:
1) An internal wire helix of stainless steel conforming to EN 10088-3:2014, numbers 1.4306, 1.4401,
1.4404 or 1.4436;
2) A multi-ply wall of layers of films and fabrics made of thermoplastics that in combination give the
required properties specified in Table 1 and provide a complete seal;
3) An external wire helix of stainless steel conforming to EN 10088-3:2014, numbers 1.4306, 1.4401,
1.4404 or 1.4436.
b) Class B:
1) An internal wire helix of stainless steel conforming to EN 10088-3:2014, numbers 1.4401, 1.4404 or
1.4436;
2) A multi-ply wall of layers of films and fabrics made of thermoplastics that in combination give the
required properties specified in Table 1 and provide a complete seal;
3) An external wire helix of stainless steel conforming to EN 10088-3:2014, numbers 1.4401, 1.4404 or
1.4436.

6 Dimensions
6.1 Internal diameters, with tolerances and minimum bend radii
When measured in accordance with EN ISO 4671, the values of the internal diameter of the hose shall
conform to Table 2. When tested by the method described in EN ISO 10619-1 the value of the minimum bend
radius shall be as given in Table 2. The hose shall show no sign of permanent deformation of the cross
section i.e. kinking.
