This document supersedes EN 1360:1996. WARNING Persons using this European Standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety problems, if any associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. ? EN 1360:2005 (E) 5 1 Scope This European Standard specifies minimum requirements for three types of hoses in two categories and two classes of hose assemblies used for measured fuel dispensing, including oxygenated fuels (up to a maximum of 15 % oxygenated compounds). The assemblies are intended for use at ambient temperatures between 30 °C and +55 °C for normal temperature class and 40 °C and +55 °C for low temperature class at a working pressure 16 bar1). 2 Normative references The following referenced documents are indispensable for the application of this document.

Hoses for this application shall be divided into two categories: d) Category M: electrically bonded e) Category : 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 '', 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 ? EN 1360:2005 (E) 7 7 Dimensions and tolerances 7.1 Internal diameters and bend radii When measured in accordance with EN ISO 4671 the internal diameter of the hose shall comply with the values given in Table 1.
