22、This European Standard is one 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. Ac
23、cording to the CEN-CENELEC Internal 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, Germa

DIN EN 13482:2013-12 EN 13482:2013 (E) 4 1 Scope This European Standard specifies require
25、ments for two types of hose and hose 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 max
26、imum temperature of the product to 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
27、 containing coal tar. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

NOTE These temperatures are the tem
34、perature of the product being conveyed inside the hose assembly. 5 Construction and materials 5.1 Type 1 and Type 2 hoses rubber smooth bore (SB) These hoses shall have the following construction: a synthetic rubber lining of minimum thickness 2,0 mm; reinforcing plies of textile or steel wire; a st
35、eel wire helix reinforcement; and an ozone resistant rubber cover of minimum thickness 2,0 mm. Internally, hoses shall have rubber linings that are smooth and free from delamination and blisters. 5.2 Type 1 and Type 2 hoses rubber rough bore (RB) These hoses shall have the following construction: an
36、 internal steel wire helix of flat or round cross-section; a synthetic rubber and/or textile lining matrix; reinforcing plies of textile or steel wire; additional helix reinforcement, if specified; and an ozone resistant rubber cover of minimum thickness 2,0 mm. Overlapped joins in the lining matrix
37、 above the internal wire helix may be visible between the pitch of the helix. 5.3 End fittings End fittings for all hose assemblies shall be of one of the following types. a) Built-in during manufacture of the hose. b) Swaged-on, either internally or externally according to the manufacturers design,
38、 after manufacture of the hose. c) Clamped-on after manufacture of the hose. Clamped-on fittings are NOT recommended for dockside hoses. For each type of end connection to the hose, an assembly type test shall be carried out, in accordance with 8.2. DIN EN 13482:2013-12 EN 13482:2013 (E) 6 To obtain
39、 an electrical resistance of 102 OHMS/assembly (maximum) the steel helix shall be connected to the end fittings. Materials for end fittings shall be steel or bronze (gunmetal/brass) and should be specified by the purchaser. NOTE Design of nipples and ferrules is the responsibility of the manufacture
