15、 conflicting national standards shall be withdrawn at the latest by April 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This d

16、ocument supersedes EN 13482:2001. In comparison with EN 13482:2001 the following fundamental changes have been made: a) Bitumen type PmB bitumen 25 (55-55A) added in Table 2; b) Normative references updated; c) Informative Annex E concerning environmental aspects added. This European Standard is one

17、 in a series of specifications for hose and hose assemblies for conveying petroleum based and associated products. It covers types of hose and hose assemblies for conveying asphalt and bitumen, which are hazardous materials at temperatures where they can flow readily. According to the CEN-CENELEC In

18、ternal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland,

19、 Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 13482:2013EN 13482:2013 (E) 4 1 Scope This European Standard specifies requirements for two types of hose and ho

20、se assembly (Type 1 and Type 2) identified by their maximum working pressures (Type 1 7 bar and Type 2 15 bar) and main use, i.e. Type 1 is for road and rail tanker use and Type 2 is for dockside use. The types are further divided into two classes related to the maximum temperature of the product to

21、 be conveyed (Class A up to 175 C and Class B up to 200 C). The hose constructions may be smooth bore (SB) or rough bore (RB). NOTE These types of hose or hose assemblies are not necessarily suitable for all types of petroleum based products or coal tar, or products containing coal tar. 2 Normative
