c) Type 3: fine wire reinforced. Hoses for this application shall be divided into two categories: d) Category M: electrically bonded e) Category Ω: electrically conductive Hoses for this application shall be divided into two temperature classes: Normal temperature class with an ambient working temperature of −30 °C to +55 °C Low temperature class (LT) with an ambient working temperature of −40 °C to +55 °C 5 Materials and construction The hose shall consist of the following: - a smooth, fuel resistant lining of rubber or thermoplastic elastomer (TPE); - a suitable reinforcement; related to type; - a non-corrugated, fuel and weather-resistant rubber or TPE cover. Hose assemblies shall be capable of conducting an electrical charge from coupling to coupling. When this capability is provided by means of metallic bonding wires, not less than two (metallic) bonding wires shall be embedded in the hose and the metal used shall have a high resistance to fatigue and corrosion. Hoses with metallic wires for electrical conductivity shall be designated 'M' and those using conductive compounds shall be designated 'Ω', the relevant mark being branded on the hose (see clause 12). 6 Pressure requirements For all types of hoses the following shall apply: a) - maximum working pressure: 16 bar b) - proof pressure: 24 bar c) - minimum bursting pressure: 48 bar SIST EN 1360:2005

The thickness of the cover shall not be less than 1,0 mm. 7.3 Concentricity When determined in accordance with EN ISO 4671, the concentricity, based on a total indicator reading between the internal diameter and the outside surface of the cover, shall not exceed 1,0 mm.
7.4 Tolerance on cut lengths For cut lengths, the tolerances on length shall be according to EN ISO 1307. The length of a hose assembly shall be measured from sealing face to sealing face of the end fittings with a tolerance from the nominal length of ± 1%. 8 Physical properties 8.1 Compounds When tested in accordance with the methods in Table 2, the physical properties of the compounds used for the lining and cover shall comply with the values given in Table 2. Tests shall be carried out either on samples taken from the hose or from moulded vulcanised sheets at a thickness of 2 mm or moulded test pieces, vulcanised to the same cured state as the production hoses.
