3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 8330:2000 apply.
4 General requirements
Quick-release couplings shall not be used under any circumstances.
The end fittings used with the hose shall be of a type that provides for tightening-up during service, for example a
clamp type to compensate for creep of the rubber compounds in the hose.

NOTE 1 Where superheated steam conditions occur, the service life of the product may be reduced.
NOTE 2 Vacuum caused by shutting off the hose assembly at both ends may precipitate "pop-corning" or separation of the
lining.
5 Classification
This document specifies two types of hoses/hose assemblies to convey saturated steam and hot water
condensate.
1)
Type 1: low-pressure steam hose, maximum working pressure 6 bar , corresponding to a temperature of 164 °C.
Type 2: high pressure steam hose, maximum working pressure 18 bar, corresponding to a temperature of 210 °C.
Each type of hose is divided into:
- Class A: a non oil-resistant cover; or
- Class B: an oil-resistant cover.
Both types and classes can be either:
a) electrically bonded, marked “M” (see Clause 11); or
b) electrically conductive, marked “Ω” (see Clause 11).
6 Materials and construction
Hoses shall consist of a lining which is resistant to steam and hot water condensate and shall be uniform in quality,
free of porosity, air holes, foreign inclusions and other defects.
The reinforcement shall be textile for Type 1 and steel wire for Type 2, either braided, spiral or cord ply
construction.
The cover shall give protection against mechanical damage and be resistant to heat, wear and environmental
effects due to weather and short-term chemical exposure. It shall be pricked equally around the periphery and
along the whole length of the hose in order to relieve any pressure built-up between the plies and the cover.
7 Dimensions and tolerances
7.1 Diameters, thickness of lining and cover, and bend radii
When determined in accordance with EN ISO 4671, the diameters, thickness of lining and cover, and the bend radii
of the hoses shall conform to the values given in Table 1.

1)
1 bar = 0,1 MPa.

102 ± 0,8 122 ± 1,6 2,5 1,5 1 000
7.2 Length of hoses and hose assemblies and tolerances
The length of the hose assembly is the overall measured distance from the sealing surfaces of the couplings from
end to end.
The deviation limits of the hoses and hose assemblies shall be as follows:
l ≤ 1 000 mm: ± 10 mm;
l > 1 000 mm: ± 1 %.
7.3 Concentricity
When determined in accordance with EN ISO 4671, the concentricity of the hose wall shall not exceed
1,0 mm for internal diameter hoses up to and including 51 mm and 1,5 mm for sizes above.
8 Physical properties of compounds
Tests shall be carried out on test sheets of 2,0 mm minimum thickness of equivalent cure to that of the hoses.
The physical properties of compounds shall conform to the values given in Table 2.
The recommended frequency of testing is illustrated in Table D.1.
